Version 1.3.0 (2011 August 4) * Add ogg_stream_flush_fill() call This produces longer packets on flush, similar to what ogg_stream_pageout_fill() does for single pages. * Windows build fixes Version 1.2.2 (2010 December 07) * Build fix (types correction) for Mac OS X * Update win32 project files to Visual Studio 2008 * ogg_stream_pageout_fill documentation fix Version 1.2.1 (2010 November 01) * Various build updates (see SVN) * Add ogg_stream_pageout_fill() to API to allow applications greater explicit flexibility in page sizing. * Documentation updates including multiplexing description, terminology and API (incl. ogg_packet_clear(), ogg_stream_pageout_fill()) * Correct possible buffer overwrite in stream encoding on 32 bit when a single packet exceed 250MB. * Correct read-buffer overrun [without side effects] under similar circumstances. * Update unit testing to work properly with new page spill heuristic. Version 1.2.0 (2010 March 25) * Alter default flushing behavior to span less often and use larger page sizes when packet sizes are large. * Build fixes for additional compilers * Documentation updates Version 1.1.4 (2009 June 24) * New async error reporting mechanism. Calls made after a fatal error are now safely handled in the event an error code is ignored * Added allocation checks useful to some embedded applications * fix possible read past end of buffer when reading 0 bits * Updates to API documentation * Build fixes Version 1.1.3 (2005 November 27) * Correct a bug in the granulepos field of pages where no packet ends * New VS2003 and XCode builds, minor fixes to other builds * documentation fixes and cleanup Version 1.1.2 (2004 September 23) * fix a bug with multipage packet assembly after seek Version 1.1.1 (2004 September 12) * various bugfixes * important bugfix for 64-bit platforms * various portability fixes * autotools cleanup from Thomas Vander Stichele * Symbian OS build support from Colin Ward at CSIRO * new multiplexed Ogg stream documentation Version 1.1 (2003 November 17) * big-endian bitpacker routines for Theora * various portability fixes * improved API documenation * RFC 3533 documentation of the format by Silvia Pfeiffer at CSIRO * RFC 3534 documentation of the application/ogg mime-type by Linus Walleij Version 1.0 (2002 July 19) * First stable release * little-endian bitpacker routines for Vorbis * basic Ogg bitstream sync and coding support libogg-1.3.1/COPYING000066400000000000000000000026721214352225400140210ustar00rootroot00000000000000Copyright (c) 2002, Xiph.org Foundation Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: - Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer. - Redistributions in binary form must reproduce the above copyright notice, this list of conditions and the following disclaimer in the documentation and/or other materials provided with the distribution. - Neither the name of the Xiph.org Foundation nor the names of its contributors may be used to endorse or promote products derived from this software without specific prior written permission.

Other modules (eg, the modules libvorbis, vorbis-tools for the Vorbis music codec, libtheora for the Theora video codec) contain the codec libraries for use with Ogg bitstreams. Directory: ./src The source for libogg, a BSD-license inplementation of the public domain Ogg bitstream format ./include Library API headers ./doc Ogg specification and libogg API documents ./win32 Win32 projects and build automation ./macosx Mac OS X project and build files = WHAT IS OGG? = Ogg project codecs use the Ogg bitstream format to arrange the raw, compressed bitstream into a more robust, useful form. For example, the Ogg bitstream makes seeking, time stamping and error recovery possible, as well as mixing several sepearate, concurrent media streams into a single physical bitstream. = CONTACT = The Ogg homepage is located at 'https://www.xiph.org/ogg/'. Up to date technical documents, contact information, source code and pre-built utilities may be found there. BUILDING FROM TARBALL DISTRIBUTIONS: ./configure make and optionally (as root): make install This will install the Ogg libraries (static and shared) into /usr/local/lib, includes into /usr/local/include and API documentation into /usr/local/share/doc. BUILDING FROM REPOSITORY SOURCE: A standard svn build should consist of nothing more than: ./autogen.sh make and as root if desired : make install BUILDING ON WIN32: Use the project file in the win32 directory. It should compile out of the box. CROSS COMPILING FROM LINUX TO WIN32: It is also possible to cross compile from Linux to windows using the MinGW cross tools and even to run the test suite under Wine, the Linux/*nix windows emulator. On Debian and Ubuntu systems, these cross compiler tools can be installed by doing: sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine Once these tools are installed its possible to compile and test by executing the following commands, or something similar depending on your system: ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc \ --build=i586-linux make make check (Build instructions for Ogg codecs such as vorbis are similar and may be found in those source modules' README files) $Id$ libogg-1.3.1/aclocal.m4000066400000000000000000012455421214352225400146340ustar00rootroot00000000000000# generated automatically by aclocal 1.11.6 -*- Autoconf -*- # Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004, # 2005, 2006, 2007, 2008, 2009, 2010, 2011 Free Software Foundation, # Inc. # This file is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. m4_ifndef([AC_AUTOCONF_VERSION], [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, [m4_warning([this file was generated for autoconf 2.69.

Ogg logical bitstream framing

Ogg bitstreams

The Ogg transport bitstream is designed to provide framing, error protection and seeking structure for higher-level codec streams that consist of raw, unencapsulated data packets, such as the Vorbis audio codec or Theora video codec.

Application example: Vorbis

Vorbis encodes short-time blocks of PCM data into raw packets of bit-packed data. These raw packets may be used directly by transport mechanisms that provide their own framing and packet-separation mechanisms (such as UDP datagrams). For stream based storage (such as files) and transport (such as TCP streams or pipes), Vorbis uses the Ogg bitstream format to provide framing/sync, sync recapture after error, landmarks during seeking, and enough information to properly separate data back into packets at the original packet boundaries without relying on decoding to find packet boundaries.

Design constraints for Ogg bitstreams

  1. True streaming; we must not need to seek to build a 100% complete bitstream.
  2. Use no more than approximately 1-2% of bitstream bandwidth for packet boundary marking, high-level framing, sync and seeking.
  3. Specification of absolute position within the original sample stream.
  4. Simple mechanism to ease limited editing, such as a simplified concatenation mechanism.
  5. Detection of corruption, recapture after error and direct, random access to data at arbitrary positions in the bitstream.

Logical and Physical Bitstreams

A logical Ogg bitstream is a contiguous stream of sequential pages belonging only to the logical bitstream. A physical Ogg bitstream is constructed from one or more than one logical Ogg bitstream (the simplest physical bitstream is simply a single logical bitstream). We describe below the exact formatting of an Ogg logical bitstream. Combining logical bitstreams into more complex physical bitstreams is described in the Ogg bitstream overview. The exact mapping of raw Vorbis packets into a valid Ogg Vorbis physical bitstream is described in the Vorbis I Specification.

Bitstream structure

An Ogg stream is structured by dividing incoming packets into segments of up to 255 bytes and then wrapping a group of contiguous packet segments into a variable length page preceded by a page header. Both the header size and page size are variable; the page header contains sizing information and checksum data to determine header/page size and data integrity.

The bitstream is captured (or recaptured) by looking for the beginning of a page, specifically the capture pattern. Once the capture pattern is found, the decoder verifies page sync and integrity by computing and comparing the checksum. At that point, the decoder can extract the packets themselves.

Packet segmentation

Packets are logically divided into multiple segments before encoding into a page. Note that the segmentation and fragmentation process is a logical one; it's used to compute page header values and the original page data need not be disturbed, even when a packet spans page boundaries.

The raw packet is logically divided into [n] 255 byte segments and a last fractional segment of < 255 bytes. A packet size may well consist only of the trailing fractional segment, and a fractional segment may be zero length. These values, called "lacing values" are then saved and placed into the header segment table.

An example should make the basic concept clear:


raw packet:
  ___________________________________________
 |______________packet data__________________| 753 bytes

lacing values for page header segment table: 255,255,243

We simply add the lacing values for the total size; the last lacing value for a packet is always the value that is less than 255. Note that this encoding both avoids imposing a maximum packet size as well as imposing minimum overhead on small packets (as opposed to, eg, simply using two bytes at the head of every packet and having a max packet size of 32k. Small packets (<255, the typical case) are penalized with twice the segmentation overhead). Using the lacing values as suggested, small packets see the minimum possible byte-aligned overhead (1 byte) and large packets, over 512 bytes or so, see a fairly constant ~.5% overhead on encoding space.

Note that a lacing value of 255 implies that a second lacing value follows in the packet, and a value of < 255 marks the end of the packet after that many additional bytes. A packet of 255 bytes (or a multiple of 255 bytes) is terminated by a lacing value of 0:


raw packet:
  _______________________________
 |________packet data____________|          255 bytes

lacing values: 255, 0

Note also that a 'nil' (zero length) packet is not an error; it consists of nothing more than a lacing value of zero in the header.

Packets spanning pages

Packets are not restricted to beginning and ending within a page, although individual segments are, by definition, required to do so. Packets are not restricted to a maximum size, although excessively large packets in the data stream are discouraged.

After segmenting a packet, the encoder may decide not to place all the resulting segments into the current page; to do so, the encoder places the lacing values of the segments it wishes to belong to the current page into the current segment table, then finishes the page. The next page is begun with the first value in the segment table belonging to the next packet segment, thus continuing the packet (data in the packet body must also correspond properly to the lacing values in the spanned pages. The segment data in the first packet corresponding to the lacing values of the first page belong in that page; packet segments listed in the segment table of the following page must begin the page body of the subsequent page).

The last mechanic to spanning a page boundary is to set the header flag in the new page to indicate that the first lacing value in the segment table continues rather than begins a packet; a header flag of 0x01 is set to indicate a continued packet. Although mandatory, it is not actually algorithmically necessary; one could inspect the preceding segment table to determine if the packet is new or continued. Adding the information to the packet_header flag allows a simpler design (with no overhead) that needs only inspect the current page header after frame capture. This also allows faster error recovery in the event that the packet originates in a corrupt preceding page, implying that the previous page's segment table cannot be trusted.

Note that a packet can span an arbitrary number of pages; the above spanning process is repeated for each spanned page boundary. Also a 'zero termination' on a packet size that is an even multiple of 255 must appear even if the lacing value appears in the next page as a zero-length continuation of the current packet. The header flag should be set to 0x01 to indicate that the packet spanned, even though the span is a nil case as far as data is concerned.

The encoding looks odd, but is properly optimized for speed and the expected case of the majority of packets being between 50 and 200 bytes (note that it is designed such that packets of wildly different sizes can be handled within the model; placing packet size restrictions on the encoder would have only slightly simplified design in page generation and increased overall encoder complexity).

The main point behind tracking individual packets (and packet segments) is to allow more flexible encoding tricks that requiring explicit knowledge of packet size. An example is simple bandwidth limiting, implemented by simply truncating packets in the nominal case if the packet is arranged so that the least sensitive portion of the data comes last.

Page header

The headering mechanism is designed to avoid copying and re-assembly of the packet data (ie, making the packet segmentation process a logical one); the header can be generated directly from incoming packet data. The encoder buffers packet data until it finishes a complete page at which point it writes the header followed by the buffered packet segments.

capture_pattern

A header begins with a capture pattern that simplifies identifying pages; once the decoder has found the capture pattern it can do a more intensive job of verifying that it has in fact found a page boundary (as opposed to an inadvertent coincidence in the byte stream).

stream_structure_version

The capture pattern is followed by the stream structure revision:


 byte value

  4  0x00

header_type_flag

The header type flag identifies this page's context in the bitstream:


 byte value

  5  bitflags: 0x01: unset = fresh packet
	               set = continued packet
	       0x02: unset = not first page of logical bitstream
                       set = first page of logical bitstream (bos)
	       0x04: unset = not last page of logical bitstream
                       set = last page of logical bitstream (eos)

absolute granule position

(This is packed in the same way the rest of Ogg data is packed; LSb of LSB first. Note that the 'position' data specifies a 'sample' number (eg, in a CD quality sample is four octets, 16 bits for left and 16 bits for right; in video it would likely be the frame number. It is up to the specific codec in use to define the semantic meaning of the granule position value). The position specified is the total samples encoded after including all packets finished on this page (packets begun on this page but continuing on to the next page do not count). The rationale here is that the position specified in the frame header of the last page tells how long the data coded by the bitstream is. A truncated stream will still return the proper number of samples that can be decoded fully.

A special value of '-1' (in two's complement) indicates that no packets finish on this page.

stream serial number

Ogg allows for separate logical bitstreams to be mixed at page granularity in a physical bitstream. The most common case would be sequential arrangement, but it is possible to interleave pages for two separate bitstreams to be decoded concurrently. The serial number is the means by which pages physical pages are associated with a particular logical stream. Each logical stream must have a unique serial number within a physical stream:


 byte value

 14  0xXX LSB
 15  0xXX
 16  0xXX
 17  0xXX MSB

page sequence no

Page counter; lets us know if a page is lost (useful where packets span page boundaries).


 byte value

 18  0xXX LSB
 19  0xXX
 20  0xXX
 21  0xXX MSB

page checksum

32 bit CRC value (direct algorithm, initial val and final XOR = 0, generator polynomial=0x04c11db7). The value is computed over the entire header (with the CRC field in the header set to zero) and then continued over the page. The CRC field is then filled with the computed value.

(A thorough discussion of CRC algorithms can be found in "A Painless Guide to CRC Error Detection Algorithms" by Ross Williams ross@ross.net.)


 byte value

 22  0xXX LSB
 23  0xXX
 24  0xXX
 25  0xXX MSB

page_segments

The number of segment entries to appear in the segment table. The maximum number of 255 segments (255 bytes each) sets the maximum possible physical page size at 65307 bytes or just under 64kB (thus we know that a header corrupted so as destroy sizing/alignment information will not cause a runaway bitstream. We'll read in the page according to the corrupted size information that's guaranteed to be a reasonable size regardless, notice the checksum mismatch, drop sync and then look for recapture).


 byte value

 26 0x00-0xff (0-255)

segment_table (containing packet lacing values)

The lacing values for each packet segment physically appearing in this page are listed in contiguous order.


 byte value

 27 0x00-0xff (0-255)
 [...]
 n  0x00-0xff (0-255, n=page_segments+26)

Total page size is calculated directly from the known header size and lacing values in the segment table. Packet data segments follow immediately after the header.

Page headers typically impose a flat .25-.5% space overhead assuming nominal ~8k page sizes. The segmentation table needed for exact packet recovery in the streaming layer adds approximately .5-1% nominal assuming expected encoder behavior in the 44.1kHz, 128kbps stereo encodings.

Bitpacking Functions

Libogg contains a basic bitpacking library that is useful for manipulating data within a buffer.

All the libogg specific functions are declared in "ogg/ogg.h".

function purpose
oggpack_writeinit Initializes a buffer for writing using this bitpacking library.
oggpack_writecheck Asynchronously checks error status of bitpacker write buffer.
oggpack_reset Clears and resets the buffer to the initial position.
oggpack_writeclear Frees the memory used by the buffer.
oggpack_readinit Initializes a buffer for reading using this bitpacking library.
oggpack_write Writes bytes to the specified location within the buffer.
oggpack_look Look at a specified number of bits, <=32, without advancing the location pointer.
oggpack_look1 Looks at one bit without advancing the location pointer.
oggpack_adv Advances the location pointer by a specified number of bits.
oggpack_adv1 Advances the location pointer by one bit.
oggpack_read Reads a specified number of bits from the buffer.
oggpack_read1 Reads one bit from the buffer.
oggpack_bytes Returns the total number of bytes contained within the buffer.
oggpack_bits Returns the total number of bits contained within the buffer.
oggpack_get_buffer Returns a pointer to the buffer encapsulated within the oggpack_buffer struct.

Base Data Structures

Libogg uses several data structures to hold data and state information.

All the libogg specific data structures are declared in "ogg/ogg.h".

datatype purpose
ogg_page This structure encapsulates data into one ogg bitstream page.
ogg_stream_state This structure contains current encode/decode data for a logical bitstream.
ogg_packet This structure encapsulates the data and metadata for a single Ogg packet.
ogg_sync_state Contains bitstream synchronization information.

libogg documentation

libogg release 1.3.1 - 20130512

Decoding

Libogg contains a set of functions used in the decoding process.

All the libogg specific functions are declared in "ogg/ogg.h".

Decoding is based around the ogg synchronization layer. The ogg_sync_state struct coordinates between incoming data and the decoder. We read data into the synchronization layer, submit the data to the stream, and output raw packets to the decoder.

Decoding through the Ogg layer follows a specific logical sequence. A read loop follows these logical steps:

In practice, streams are more complex, and Ogg also must handle headers, incomplete or dropped pages, and other errors in input.

function purpose
ogg_sync_init Initializes an Ogg bitstream.
ogg_sync_clear Clears the status information from the synchronization struct.
ogg_sync_reset Resets the synchronization status to initial values.
ogg_sync_destroy Frees the synchronization struct.
ogg_sync_check Check for asynchronous errors.
ogg_sync_buffer Exposes a buffer from the synchronization layer in order to read data.
ogg_sync_wrote Tells the synchronization layer how many bytes were written into the buffer.
ogg_sync_pageseek Finds the borders of pages and resynchronizes the stream.
ogg_sync_pageout Outputs a page from the synchronization layer.
ogg_stream_pagein Submits a complete page to the stream layer.
ogg_stream_packetout Outputs a packet to the codec-specific decoding engine.
ogg_stream_packetpeek Provides access to the next packet in the bitstream without advancing decoding.

libogg documentation

libogg release 1.3.1 - 20130512

Encoding

Libogg contains a set of functions used in the encoding process.

All the libogg specific functions are declared in "ogg/ogg.h".

When encoding, the encoding engine will output raw packets which must be placed into an Ogg bitstream.

Raw packets are inserted into the stream, and an ogg_page is output when enough packets have been written to create a full page. The pages output are pointers to buffered packet segments, and can then be written out and saved as an ogg stream.

There are a couple of basic steps:

  • Use the encoding engine to produce a raw packet of data.
  • Call ogg_stream_packetin to submit a raw packet to the stream.
  • Use ogg_stream_pageout to output a page, if enough data has been submitted. Otherwise, continue submitting data.


function purpose
ogg_stream_packetin Submits a raw packet to the streaming layer, so that it can be formed into a page.
ogg_stream_iovecin iovec version of ogg_stream_packetin() above.
ogg_stream_pageout Outputs a completed page if the stream contains enough packets to form a full page.
ogg_stream_pageout_fill Similar to ogg_stream_pageout(), but specifies a page spill threshold in bytes.
ogg_stream_flush Forces any remaining packets in the stream to be returned as a page of any size.
ogg_stream_flush_fill Similar to ogg_stream_flush(), but specifies a page spill threshold in bytes.

libogg release 1.3.1 - 20130512

General Functions

Libogg contains several functions which are generally useful when using Ogg streaming, whether encoding or decoding.

All the libogg specific functions are declared in "ogg/ogg.h".

These functions can be used to manipulate some of the basic elements of Ogg - streams and pages. Streams and pages are important during both the encode and decode process.
function purpose
ogg_stream_init Initializes an Ogg bitstream.
ogg_stream_clear Clears the storage within the Ogg stream, but does not free the stream itself.
ogg_stream_reset Resets the stream status to its initial position.
ogg_stream_destroy Frees the entire Ogg stream.
ogg_stream_check Check for asyncronous errors.
ogg_stream_eos Indicates whether we are at the end of the stream.
ogg_page_version Returns the version of ogg_page that this stream/page uses
ogg_page_continued Indicates if the current page contains a continued packet from the last page.
ogg_page_packets Indicates the number of packets contained in a page.
ogg_page_bos Indicates if the current page is the beginning of the stream.
ogg_page_eos Indicates if the current page is the end of the stream.
ogg_page_granulepos Returns the precise playback location of this page.
ogg_page_serialno Returns the unique serial number of the logical bitstream associated with this page.
ogg_page_pageno Returns the sequential page number for this page.
ogg_packet_clear Clears the ogg_packet structure.
ogg_page_checksum_set Checksums an ogg_page.

ogg_packet

declared in "ogg/ogg.h"

The ogg_packet struct encapsulates the data for a single raw packet of data and is used to transfer data between the ogg framing layer and the handling codec. 


typedef struct {
  unsigned char *packet;
  long  bytes;
  long  b_o_s;
  long  e_o_s;

  ogg_int64_t  granulepos;
  ogg_int64_t  packetno; 

} ogg_packet;

Relevant Struct Members

packet
Pointer to the packet's data. This is treated as an opaque type by the ogg layer.
bytes
Indicates the size of the packet data in bytes. Packets can be of arbitrary size.
b_o_s
Flag indicating whether this packet begins a logical bitstream. 1 indicates this is the first packet, 0 indicates any other position in the stream.
e_o_s
Flag indicating whether this packet ends a bitstream. 1 indicates the last packet, 0 indicates any other position in the stream.
granulepos
A number indicating the position of this packet in the decoded data. This is the last sample, frame or other unit of information ('granule') that can be completely decoded from this packet.
packetno
Sequential number of this packet in the ogg bitstream.

    ogg_page

    declared in "ogg/ogg.h"

    The ogg_page struct encapsulates the data for an Ogg page.

    Ogg pages are the fundamental unit of framing and interleave in an ogg bitstream. They are made up of packet segments of 255 bytes each. There can be as many as 255 packet segments per page, for a maximum page size of a little under 64 kB. This is not a practical limitation as the segments can be joined across page boundaries allowing packets of arbitrary size. In practice many applications will not completely fill all pages because they flush the accumulated packets periodically order to bound latency more tightly.

    For a complete description of ogg pages and headers, please refer to the framing document. 
    
typedef struct {
  unsigned char *header;
  long           header_len;
  unsigned char *body;
  long           body_len;
} ogg_page;

    Relevant Struct Members

    header
    Pointer to the page header for this page. The exact contents of this header are defined in the framing spec document.
    header_len
    Length of the page header in bytes.
    body
    Pointer to the data for this page.
    body_len
    Length of the body data in bytes.

    libogg documentation

    libogg release 1.3.1 - 20130512

    ogg_stream_check

    declared in "ogg/ogg.h";

    This function is used to check the error or readiness condition of an ogg_stream_state structure.

    It is safe practice to ignore unrecoverable errors (such as an internal error caused by a malloc() failure) returned by ogg stream synchronization calls. Should an internal error occur, the ogg_stream_state structure will be cleared (equivalent to a call to ogg_stream_clear) and subsequent calls using this ogg_stream_state will be noops. Error detection is then handled via a single call to ogg_stream_check at the end of the operational block. 



    
int ogg_stream_check(ogg_stream_state *os);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct.

    Return Values

  • 0 is returned if the ogg_stream_state structure is initialized and ready.
  • nonzero is returned if the structure was never initialized, or if an unrecoverable internal error occurred in a previous call using the passed in ogg_stream_state struct.

    declared in "ogg/ogg.h";

    This function frees the internal memory used by the ogg_stream_state struct as well as the structure itself.

    This should be called when you are done working with an ogg stream. It can also be called to make sure that the struct does not exist.

    It calls free() on its argument, so if the ogg_stream_state is not malloc()'d or will otherwise be freed by your own code, use ogg_stream_clear instead.

    libogg documentation

    libogg release 1.3.1 - 20130512

    ogg_stream_flush

    declared in "ogg/ogg.h";

    This function checks for remaining packets inside the stream and forces remaining packets into a page, regardless of the size of the page.

    This should only be used when you want to flush an undersized page from the middle of the stream. Otherwise, ogg_stream_pageout or ogg_stream_pageout_fill should always be used.

    This function can also be used to verify that all packets have been flushed. If the return value is 0, all packets have been placed into a page. Like ogg_stream_pageout, it should generally be called in a loop until available packet data has been flushes, since even a single packet may span multiple pages. 

    
int ogg_stream_flush(ogg_stream_state *os, ogg_page *og);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct, which represents the current logical bitstream.
    og
    Pointer to a page of data. The remaining packets in the stream will be placed into this page, if any remain.

    Return Values

  • 0 means that all packet data has already been flushed into pages, and there are no packets to put into the page. 0 is also returned in the case of an ogg_stream_state that has been cleared explicitly or implicitly due to an internal error.
  • Nonzero means that remaining packets have successfully been flushed into the page.

    ogg_stream_flush_fill

    declared in "ogg/ogg.h";

    This function flushes available packets into pages, similar to ogg_stream_flush(), but allows applications to explicitly request a specific page spill size.

    This function checks for remaining packets inside the stream and forces remaining packets into pages of approximately the requested size. This should be used when you want to flush all remaining data from a stream. ogg_stream_flush may be used instead if a particular page size isn't important.

    This function can be used to verify that all packets have been flushed. If the return value is 0, all packets have been placed into a page. Generally speaking, it should be called in a loop until all packets are flushed, since even a single packet may span multiple pages. 

    
int ogg_stream_flush_fill(ogg_stream_state *os, ogg_page *og, int fillbytes);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct, which represents the current logical bitstream.
    og
    Pointer to a page of data. The remaining packets in the stream will be placed into this page, if any remain.
    fillbytes
    Packet data watermark in bytes.

    Return Values

  • 0 means that all packet data has already been flushed into pages, and there are no packets to put into the page. 0 is also returned in the case of an ogg_stream_state that has been cleared explicitly or implicitly due to an internal error.
  • Nonzero means that remaining packets have successfully been flushed into the page.

    ogg_stream_iovecin

    declared in "ogg/ogg.h";

    This function submits packet data (in the form of an array of ogg_iovec_t, rather than using an ogg_packet structure) to the bitstream for page encapsulation. After this is called, more packets can be submitted, or pages can be written out.

    In a typical encoding situation, this should be used after filling a packet with data. The data in the packet is copied into the internal storage managed by the ogg_stream_state, so the caller is free to alter the contents of os after this call has returned. 

    
int ogg_stream_iovecin(ogg_stream_state *os, ogg_iovec_t *iov, int count, long e_o_s, ogg_int64_t granulepos);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct.
    iov
    Length-encoded buffers held in an array of ogg_iovec_t.
    count
    Length of the iov array.
    e_o_s
    End of stream flag, analagous to the e_o_s field in an ogg_packet.
    granulepos
    Granule position value, analagous to the granpos field in an ogg_packet.

    Return Values

  • 0 returned on success. -1 returned in the event of internal error.

    libogg documentation

    libogg release 1.3.1 - 20130512

    ogg_stream_packetout

    declared in "ogg/ogg.h";

    This function assembles a data packet for output to the codec decoding engine. The data has already been submitted to the ogg_stream_state and broken into segments. Each successive call returns the next complete packet built from those segments.

    In a typical decoding situation, this should be used after calling ogg_stream_pagein() to submit a page of data to the bitstream. If the function returns 0, more data is needed and another page should be submitted. A non-zero return value indicates successful return of a packet.

    The op is filled in with pointers to memory managed by the stream state and is only valid until the next call. The client must copy the packet data if a longer lifetime is required.



    
int ogg_stream_packetout(ogg_stream_state *os,ogg_packet *op);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct. Before this function is called, an ogg_page should be submitted to the stream using ogg_stream_pagein().
    op
    Pointer to the packet to be filled in with pointers to the new data. This will typically be submitted to a codec for decode after this function is called. The pointers are only valid until the next call on this stream state.

    Return Values

    • -1 if we are out of sync and there is a gap in the data. This is usually a recoverable error and subsequent calls to ogg_stream_packetout are likely to succeed. op has not been updated.
    • 0 if there is insufficient data available to complete a packet, or on unrecoverable internal error occurred. op has not been updated.
    • 1 if a packet was assembled normally. op contains the next packet from the stream.

    ogg_stream_packetpeek

    declared in "ogg/ogg.h";

    This function attempts to assemble a raw data packet and returns it without advancing decoding.

    In a typical situation, this would be called speculatively after ogg_stream_pagein() to check the packet contents before handing it off to a codec for decompression. To advance page decoding and remove the packet from the sync structure, call ogg_stream_packetout().



    
int ogg_stream_packetpeek(ogg_stream_state *os,ogg_packet *op);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct. Before this function is called, an ogg_page should be submitted to the stream using ogg_stream_pagein().
    op
    Pointer to the next packet available in the bitstream, if any. A NULL value may be passed in the case of a simple "is there a packet?" check.

    Return Values

    • -1 if there's no packet available due to lost sync or a hole in the data.
    • 0 if there is insufficient data available to complete a packet, or on unrecoverable internal error occurred.
    • 1 if a packet is available.

    declared in "ogg/ogg.h";

    This function adds a complete page to the bitstream.

    In a typical decoding situation, this function would be called after using ogg_sync_pageout to create a valid ogg_page struct.

    Internally, this function breaks the page into packet segments in preparation for outputting a valid packet to the codec decoding layer. 

    
int ogg_stream_pagein(ogg_stream_state *os, ogg_page *og);

    Parameters

    os
    Pointer to a previously declared ogg_stream_state struct, which represents the current logical bitstream.
    og
    Pointer to a page of data. The data inside this page is being submitted to the streaming layer in order to be allocated into packets.

    Return Values

  • -1 indicates failure. This means that the serial number of the page did not match the serial number of the bitstream, the page version was incorrect, or an internal error accurred.
  • 0 means that the page was successfully submitted to the bitstream.

    libogg release 1.3.1 - 20130512

    ogg_stream_pageout

    declared in "ogg/ogg.h";

    This function forms packets into pages.

    In a typical encoding situation, this would be called after using ogg_stream_packetin() to submit data packets to the bitstream. Internally, this function assembles the accumulated packet bodies into an Ogg page suitable for writing to a stream. The function is typically called in a loop until there are no more pages ready for output.

    This function will only return a page when a "reasonable" amount of packet data is available. Normally this is appropriate since it limits the overhead of the Ogg page headers in the bitstream, and so calling ogg_stream_pageout() after ogg_stream_packetin() should be the common case. Call ogg_stream_flush() if immediate page generation is desired. This may be occasionally necessary, for example, to limit the temporal latency of a variable bitrate stream.



    
int ogg_stream_pageout(ogg_stream_state *os, ogg_page *og);

    Parameters

    os
    Pointer to a previously declared ogg_stream struct, which represents the current logical bitstream.
    og
    Pointer to an ogg_page structure to fill in. Data pointed to is owned by libogg. The structure is valid until the next call to ogg_stream_pageout(), ogg_stream_packetin(), or ogg_stream_flush().

    Return Values

  • Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In this case og is not modified.
  • Non-zero means that a page has been completed and returned.

    libogg release 1.3.1 - 20130512

    ogg_sync_buffer

    declared in "ogg/ogg.h";

    This function is used to provide a properly-sized buffer for writing.

    Buffer space which has already been returned is cleared, and the buffer is extended as necessary by the size plus some additional bytes. Within the current implementation, an extra 4096 bytes are allocated, but applications should not rely on this additional buffer space.

    The buffer exposed by this function is empty internal storage from the ogg_sync_state struct, beginning at the fill mark within the struct.

    A pointer to this buffer is returned to be used by the calling application. 

    
char *ogg_sync_buffer(ogg_sync_state *oy, long size);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct.
    size
    Size of the desired buffer. The actual size of the buffer returned will be this size plus some extra bytes (currently 4096).

    Return Values

  • Returns a pointer to the newly allocated buffer or NULL on error

    ogg_sync_check

    declared in "ogg/ogg.h";

    This function is used to check the error or readiness condition of an ogg_sync_state structure.

    It is safe practice to ignore unrecoverable errors (such as an internal error caused by a malloc() failure) returned by ogg stream synchronization calls. Should an internal error occur, the ogg_sync_state structure will be cleared (equivalent to a call to ogg_sync_clear) and subsequent calls using this ogg_sync_state will be noops. Error detection is then handled via a single call to ogg_sync_check at the end of the operational block. 



    
int ogg_sync_check(ogg_sync_state *oy);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct.

    Return Values

  • 0 is returned if the ogg_sync_state structure is initialized and ready.
  • nonzero is returned if the structure was never initialized, or if an unrecoverable internal error occurred in a previous call using the passed in ogg_sync_state struct.

    ogg_sync_destroy

    declared in "ogg/ogg.h";

    This function is used to destroy an ogg_sync_state struct and free all memory used.

    Note this calls free() on its argument so you should only use this function if you've allocated the ogg_sync_state on the heap. If it is allocated on the stack, or it will otherwise be freed by your own code, use ogg_sync_clear instead to release just the internal memory.



    
int ogg_sync_destroy(ogg_sync_state *oy);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct.

    Return Values

  • 0 is always returned.

    declared in "ogg/ogg.h";

    This function is used to initialize an ogg_sync_state struct to a known initial value in preparation for manipulation of an Ogg bitstream.

    The ogg_sync struct is important when decoding, as it synchronizes retrieval and return of data. 

    
int ogg_sync_init(ogg_sync_state *oy);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct. After this function call, this struct has been initialized.

    Return Values

  • 0 is always returned.

    libogg documentation

    libogg release 1.3.1 - 20130512

    ogg_sync_pageout

    declared in "ogg/ogg.h";

    This function takes the data stored in the buffer of the ogg_sync_state struct and inserts them into an ogg_page.

    In an actual decoding loop, this function should be called first to ensure that the buffer is cleared. The example code below illustrates a clean reading loop which will fill and output pages.

    Caution:This function should be called before reading into the buffer to ensure that data does not remain in the ogg_sync_state struct. Failing to do so may result in a memory leak. See the example code below for details. 

    
int ogg_sync_pageout(ogg_sync_state *oy, ogg_page *og);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct. Normally, the internal storage of this struct should be filled with newly read data and verified using ogg_sync_wrote.
    og
    Pointer to page struct filled by this function.

    Return Values

  • -1 returned if stream has not yet captured sync (bytes were skipped).
  • 0 returned if more data needed or an internal error occurred.
  • 1 indicated a page was synced and returned.

    • Example Usage

    if (ogg_sync_pageout(&oy, &og) != 1) {
	buffer = ogg_sync_buffer(&oy, 8192);
	bytes = fread(buffer, 1, 8192, stdin);
	ogg_sync_wrote(&oy, bytes);
}

    ogg_sync_pageseek

    declared in "ogg/ogg.h";

    This function synchronizes the ogg_sync_state struct to the next ogg_page.

    This is useful when seeking within a bitstream. ogg_sync_pageseek will synchronize to the next page in the bitstream and return information about how many bytes we advanced or skipped in order to do so. 

    
int ogg_sync_pageseek(ogg_sync_state *oy, ogg_page *og);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct.
    og
    Pointer to a page (or an incomplete page) of data. This is the page we are attempting to sync.

    Return Values

  • -n means that we skipped n bytes within the bitstream.
  • 0 means that the page isn't ready and we need more data, or than an internal error occurred. No bytes have been skipped.
  • n means that the page was synced at the current location, with a page length of n bytes.

    libogg release 1.3.1 - 20130512

    ogg_sync_wrote

    declared in "ogg/ogg.h";

    This function is used to tell the ogg_sync_state struct how many bytes we wrote into the buffer.

    The general proceedure is to request a pointer into an internal ogg_sync_state buffer by calling ogg_sync_buffer(). The buffer is then filled up to the requested size with new input, and ogg_sync_wrote() is called to advance the fill pointer by however much data was actually available.


    
int ogg_sync_wrote(ogg_sync_state *oy, long bytes);

    Parameters

    oy
    Pointer to a previously declared ogg_sync_state struct.
    bytes
    Number of bytes of new data written.

    Return Values

  • -1 if the number of bytes written overflows the internal storage of the ogg_sync_state struct or an internal error occurred.
  • 0 in all other cases.

    libogg documentation

    libogg release 1.3.1 - 20130512

    oggpack_writecheck

    declared in "ogg/ogg.h";

    This function checks the readiness status of an oggpack_buffer previously initialized for writing using the Ogg bitpacking functions. A write buffer that encounters an error (such as a failed malloc) will clear its internal state and release any in-use memory, flagging itself as 'not ready'. Subsequent attempts to write using the buffer will silently fail. This error state may be detected at any later time by using oggpack_writecheck(). It is safe but not necessary to call oggpack_writeclear() on a buffer that has flagged an error and released its resources.

    Important note to developers: Although libogg checks the results of memory allocations, these checks are only useful on a narrow range of embedded platforms. Allocation checks perform no useful service on a general purpose desktop OS where pages are routinely overallocated and all allocations succeed whether memory is available or not. The only way to detect an out of memory condition on the vast majority of OSes is to watch for and capture segmentation faults. This function is useful only to embedded developers. 

    
int  oggpack_writecheck(oggpack_buffer *b);

    Parameters

    b
    An oggpack_buffer previously initialized for writing.

    Return Values

  • zero: buffer is ready for writing
  • nonzero: buffer is not ready or encountered an error

    oggpack_writecopy

    declared in "ogg/ogg.h";

    This function copies a sequence of bits from a source buffer into an oggpack_buffer.

    The oggpack_buffer must already be initialized for writing using oggpack_writeinit.

    Only 32 bits can be written at a time.



    
void  oggpack_writecopy(oggpack_buffer *b, void *source, long bits);

    Parameters

    b
    Buffer to be used for writing.
    source
    A pointer to the data to be written into the buffer.
    bits
    The number of bits to be copied into the buffer.

    Return Values

  • No values are returned.

    Page Multiplexing and Ordering in a Physical Ogg Stream

    The low-level mechanisms of an Ogg stream (as described in the Ogg Bitstream Overview) provide means for mixing multiple logical streams and media types into a single linear-chronological stream. This document specifies the high-level arrangement and use of page structure to multiplex multiple streams of mixed media type within a physical Ogg stream.

    Design Elements

    The design and arrangement of the Ogg container format is governed by several high-level design decisions that form the reasoning behind specific low-level design decisions.

    Linear media

    The Ogg bitstream is intended to encapsulate chronological, time-linear mixed media into a single delivery stream or file. The design is such that an application can always encode and/or decode a full-featured bitstream in one pass with no seeking and minimal buffering. Seeking to provide optimized encoding (such as two-pass encoding) or interactive decoding (such as scrubbing or instant replay) is not disallowed or discouraged, however no bitstream feature must require nonlinear operation on the bitstream.

    Multiplexing

    Ogg bitstreams multiplex multiple logical streams into a single physical stream at the page level. Each page contains an abstract time stamp (the Granule Position) that represents an absolute time landmark within the stream. After the pages representing stream headers (all logical stream headers occur at the beginning of a physical bitstream section before any logical stream data), logical stream data pages are arranged in a physical bitstream in strict non-decreasing order by chronological absolute time as specified by the granule position.

    The only exception to arranging pages in strictly ascending time order by granule position is those pages that do not set the granule position value. This is a special case when exceptionally large packets span multiple pages; the specifics of handling this special case are described later under 'Continuous and Discontinuous Streams'.

    Seeking

    Ogg is designed to use an interpolated bisection search to implement exact positional seeking. Interpolated bisection search is a spec-mandated mechanism.

    An index may improve objective performance, but it seldom improves subjective performance outside of a few high-latency use cases and adds no additional functionality as bisection search delivers the same functionality for both one- and two-pass stream types. For these reasons, use of indexes is discouraged, except in cases where an index provides demonstrable and noticable performance improvement.

    Seek operations are by absolute time; a direct bisection search must find the exact time position requested. Information in the Ogg bitstream is arranged such that all information to be presented for playback from the desired seek point will occur at or after the desired seek point. Seek operations are neither 'fuzzy' nor heuristic.

    Although key frame handling in video appears to be an exception to "all needed playback information lies ahead of a given seek", key frames can still be handled directly within this indexless framework. Seeking to a key frame in video (as well as seeking in other media types with analogous restraints) is handled as two seeks; first a seek to the desired time which extracts state information that decodes to the time of the last key frame, followed by a second seek directly to the key frame. The location of the previous key frame is embedded as state information in the granulepos; this mechanism is described in more detail later.

    Continuous and Discontinuous Streams

    Logical streams within a physical Ogg stream belong to one of two categories, "Continuous" streams and "Discontinuous" streams. Although these are discussed in more detail later, the distinction is important to a high-level understanding of how to buffer an Ogg stream.

    A stream that provides a gapless, time-continuous media type with a fine-grained timebase is considered to be 'Continuous'. A continuous stream should never be starved of data. Clear examples of continuous data types include broadcast audio and video.

    A stream that delivers data in a potentially irregular pattern or with widely spaced timing gaps is considered to be 'Discontinuous'. A discontinuous stream may be best thought of as data representing scattered events; although they happen in order, they are typically unconnected data often located far apart. One possible example of a discontinuous stream types would be captioning. Although it's possible to design captions as a continuous stream type, it's most natural to think of captions as widely spaced pieces of text with little happening between.

    The fundamental design distinction between continuous and discontinuous streams concerns buffering.

    Buffering

    Because a continuous stream is, by definition, gapless, Ogg buffering is based on the simple premise of never allowing any active continuous stream to starve for data during decode; buffering proceeds ahead until all continuous streams in a physical stream have data ready to decode on demand.

    Discontinuous stream data may occur on a fairly regular basis, but the timing of, for example, a specific caption is impossible to predict with certainty in most captioning systems. Thus the buffering system should take discontinuous data 'as it comes' rather than working ahead (for a potentially unbounded period) to look for future discontinuous data. As such, discontinuous streams are ignored when managing buffering; their pages simply 'fall out' of the stream when continuous streams are handled properly.

    Buffering requirements need not be explicitly declared or managed for the encoded stream; the decoder simply reads as much data as is necessary to keep all continuous stream types gapless (also ensuring discontinuous data arrives in time) and no more, resulting in optimum implicit buffer usage for a given stream. Because all pages of all data types are stamped with absolute timing information within the stream, inter-stream synchronization timing is always explicitly maintained without the need for explicitly declared buffer-ahead hinting.

    Further details, mechanisms and reasons for the differing arrangement and behavior of continuous and discontinuous streams is discussed later.

    Whole-stream navigation

    Ogg is designed so that the simplest navigation operations treat the physical Ogg stream as a whole summary of its streams, rather than navigating each interleaved stream as a separate entity.

    First Example: seeking to a desired time position in a multiplexed (or unmultiplexed) Ogg stream can be accomplished through a bisection search on time position of all pages in the stream (as encoded in the granule position). More powerful searches (such as a key frame-aware seek within video) are also possible with additional search complexity, but similar computational complexity.

    Second Example: A bitstream section may consist of three multiplexed streams of differing lengths. The result of multiplexing these streams should be thought of as a single mixed stream with a length equal to the longest of the three component streams. Although it is also possible to think of the multiplexed results as three concurrent streams of different lengths and it is possible to recover the three original streams, it will also become obvious that once multiplexed, it isn't possible to find the internal lengths of the component streams without a linear search of the whole bitstream section. However, it is possible to find the length of the whole bitstream section easily (in near-constant time per section) just as it is for a single-media unmultiplexed stream.

    Granule Position

    Description

    The Granule Position is a signed 64 bit field appearing in the header of every Ogg page. Although the granule position represents absolute time within a logical stream, its value does not necessarily directly encode a simple timestamp. It may represent frames elapsed (as in Vorbis), a simple timestamp, or a more complex bit-division encoding (such as in Theora). The exact encoding of the granule position is up to a specific codec.

    The granule position is governed by the following rules:

    • Granule Position must always increase forward or remain equal from page to page, be unset, or be zero for a header page. The absolute time to which any correct sequence of granule position maps must similarly always increase forward or remain equal. (A codec may make use of data, such as a control sequence, that only affects codec working state without producing data and thus advancing granule position and time. Although the packet sequence number increases in this case, the granule position, and thus the time position, do not.)
    • Granule position may only be unset if there no packet defining a time boundary on the page (that is, if no packet in a continuous stream ends on the page, or no packet in a discontinuous stream begins on the page. This will be discussed in more detail under Continuous and Discontinuous streams).
    • A codec must be able to translate a given granule position value to a unique, deterministic absolute time value through direct calculation. A codec is not required to be able to translate an absolute time value into a unique granule position value.
    • Codecs shall choose a granule position definition that allows that codec means to seek as directly as possible to an immediately decodable point, such as the bit-divided granule position encoding of Theora allows the codec to seek efficiently to key frame without using an index. That is, additional information other than absolute time may be encoded into a granule position value so long as the granule position obeys the above points.

    Example: timestamp

    In general, a codec/stream type should choose the simplest granule position encoding that addresses its requirements. The examples here are by no means exhaustive of the possibilities within Ogg.

    A simple granule position could encode a timestamp directly. For example, a granule position that encoded milliseconds from beginning of stream would allow a logical stream length of over 100,000,000,000 days before beginning a new logical stream (to avoid the granule position wrapping).

    Example: framestamp

    A simple millisecond timestamp granule encoding might suit many stream types, but a millisecond resolution is inappropriate to, eg, most audio encodings where exact single-sample resolution is generally a requirement. A millisecond is both too large a granule and often does not represent an integer number of samples.

    In the event that audio frames are always encoded as the same number of samples, the granule position could simply be a linear count of frames since beginning of stream. This has the advantages of being exact and efficient. Position in time would simply be [granule_position] * [samples_per_frame] / [samples_per_second].

    Example: samplestamp (Vorbis)

    Frame counting is insufficient in codecs such as Vorbis where an audio frame [packet] encodes a variable number of samples. In Vorbis's case, the granule position is a count of the number of raw samples from the beginning of stream; the absolute time of a granule position is [granule_position] / [samples_per_second].

    Example: bit-divided framestamp (Theora)

    Some video codecs may be able to use the simple framestamp scheme for granule position. However, most modern video codecs introduce at least the following complications:

    • video frames are relatively far apart compared to audio samples; for this reason, the point at which a video frame changes to the next frame is usually a strictly defined offset within the frame 'period'. That is, video at 50fps could just as easily define frame transitions <.015, .035, .055...> as at <.00, .02, .04...>.
    • frame rates often include drop-frames, leap-frames or other rational-but-non-integer timings.
    • Decode must begin at a 'key frame' or 'I frame'. Keyframes usually occur relatively seldom.

    The first two points can be handled straightforwardly via the fact that the codec has complete control mapping granule position to absolute time; non-integer frame rates and offsets can be set in the codec's initial header, and the rest is just arithmetic.

    The third point appears trickier at first glance, but it too can be handled through the granule position mapping mechanism. Here we arrange the granule position in such a way that granule positions of key frames are easy to find. Divide the granule position into two fields; the most-significant bits are an absolute frame counter, but it's only updated at each key frame. The least significant bits encode the number of frames since the last key frame. In this way, each granule position both encodes the absolute time of the current frame as well as the absolute time of the last key frame.

    Seeking to a most recent preceding key frame is then accomplished by first seeking to the original desired point, inspecting the granulepos of the resulting video page, extracting from that granulepos the absolute time of the desired key frame, and then seeking directly to that key frame's page. Of course, it's still possible for an application to ignore key frames and use a simpler seeking algorithm (decode would be unable to present decoded video until the next key frame). Surprisingly many player applications do choose the simpler approach.

    granule position, packets and pages

    Although each packet of data in a logical stream theoretically has a specific granule position, only one granule position is encoded per page. It is possible to encode a logical stream such that each page contains only a single packet (so that granule positions are preserved for each packet), however a one-to-one packet/page mapping is not intended to be the general case.

    Because Ogg functions at the page, not packet, level, this once-per-page time information provides Ogg with the finest-grained time information is can use. Ogg passes this granule positioning data to the codec (along with the packets extracted from a page); it is the responsibility of codecs to track timing information at granularities finer than a single page.

    start-time and end-time positioning

    A granule position represents the instantaneous time location between two pages. However, continuous streams and discontinuous streams differ on whether the granulepos represents the end-time of the data on a page or the start-time. Continuous streams are 'end-time' encoded; the granulepos represents the point in time immediately after the last data decoded from a page. Discontinuous streams are 'start-time' encoded; the granulepos represents the point in time of the first data decoded from the page.

    An Ogg stream type is declared continuous or discontinuous by its codec. A given codec may support both continuous and discontinuous operation so long as any given logical stream is continuous or discontinuous for its entirety and the codec is able to ascertain (and inform the Ogg layer) as to which after decoding the initial stream header. The majority of codecs will always be continuous (such as Vorbis) or discontinuous (such as Writ).

    Start- and end-time encoding do not affect multiplexing sort-order; pages are still sorted by the absolute time a given granulepos maps to regardless of whether that granulepos represents start- or end-time.

    Multiplex/Demultiplex Division of Labor

    The Ogg multiplex/demultiplex layer provides mechanisms for encoding raw packets into Ogg pages, decoding Ogg pages back into the original codec packets, determining the logical structure of an Ogg stream, and navigating through and synchronizing with an Ogg stream at a desired stream location. Strict multiplex/demultiplex operations are entirely in the Ogg domain and require no intervention from codecs.

    Implementation of more complex operations does require codec knowledge, however. Unlike other framing systems, Ogg maintains strict separation between framing and the framed bitstream data; Ogg does not replicate codec-specific information in the page/framing data, nor does Ogg blur the line between framing and stream data/metadata. Because Ogg is fully data-agnostic toward the data it frames, operations which require specifics of bitstream data (such as 'seek to key frame') also require interaction with the codec layer (because, in this example, the Ogg layer is not aware of the concept of key frames). This is different from systems that blur the separation between framing and stream data in order to simplify the separation of code. The Ogg system purposely keeps the distinction in data simple so that later codec innovations are not constrained by framing design.

    For this reason, however, complex seeking operations require interaction with the codecs in order to decode the granule position of a given stream type back to absolute time or in order to find 'decodable points' such as key frames in video.

    Ogg bitstream overview

    This document serves as starting point for understanding the design and implementation of the Ogg container format. If you're new to Ogg or merely want a high-level technical overview, start reading here. Other documents linked from the index page give distilled technical descriptions and references of the container mechanisms. This document is intended to aid understanding.

    Container format design points

    Ogg is intended to be a simplest-possible container, concerned only with framing, ordering, and interleave. It can be used as a stream delivery mechanism, for media file storage, or as a building block toward implementing a more complex, non-linear container (for example, see the Skeleton or Annodex/CMML).

    The Ogg container is not intended to be a monolithic 'kitchen-sink'. It exists only to frame and deliver in-order stream data and as such is vastly simpler than most other containers. Elementary and multiplexed streams are both constructed entirely from a single building block (an Ogg page) comprised of eight fields totalling twenty-eight bytes (the page header) a list of packet lengths (up to 255 bytes) and payload data (up to 65025 bytes). The structure of every page is the same. There are no optional fields or alternate encodings.

    Stream and media metadata is contained in Ogg and not built into the Ogg container itself. Metadata is thus compartmentalized and layered rather than part of a monolithic design, an especially good idea as no two groups seem able to agree on what a complete or complete-enough metadata set should be. In this way, the container and container implementation are isolated from unnecessary metadata design flux.

    Streaming

    The Ogg container is primarily a streaming format, encapsulating chronological, time-linear mixed media into a single delivery stream or file. The design is such that an application can always encode and/or decode all features of a bitstream in one pass with no seeking and minimal buffering. Seeking to provide optimized encoding (such as two-pass encoding) or interactive decoding (such as scrubbing or instant replay) is not disallowed or discouraged, however no container feature requires nonlinear access of the bitstream.

    Variable Bit Rate, Variable Payload Size

    Ogg is designed to contain any size data payload with bounded, predictable efficiency. Ogg packets have no maximum size and a zero-byte minimum size. There is no restriction on size changes from packet to packet. Variable size packets do not require the use of any optional or additional container features. There is no optimal suggested packet size, though special consideration was paid to make sure 50-200 byte packets were no less efficient than larger packet sizes. The original design criteria was a 2% overhead at 50 byte packets, dropping to a maximum working overhead of 1% with larger packets, and a typical working overhead of .5-.7% for most practical uses.

    Simple pagination

    Ogg is a byte-aligned container with no context-dependent, optional or variable-length fields. Ogg requires no repacking of codec data. The page structure is written out in-line as packet data is submitted to the streaming abstraction. In addition, it is possible to implement both Ogg mux and demux as MT-hot zero-copy abstractions (as is done in the Tremor sourcebase).

    Capture

    Ogg is designed for efficient and immediate stream capture with high confidence. Although packets have no size limit in Ogg, pages are a maximum of just under 64kB meaning that any Ogg stream can be captured with confidence after seeing 128kB of data or less [worst case; typical figure is 6kB] from any random starting point in the stream.

    Seeking

    Ogg implements simple coarse- and fine-grained seeking by design.

    Coarse seeking may be performed by simply 'moving the tone arm' to a new position and 'dropping the needle'. Rapid capture with accompanying timecode from any location in an Ogg file is guaranteed by the stream design. From the acquisition of the first timecode, all data needed to play back from that time code forward is ahead of the stream cursor.

    Ogg implements full sample-granularity seeking using an interpolated bisection search built on the capture and timecode mechanisms used by coarse seeking. As above, once a search finds the desired timecode, all data needed to play back from that time code forward is ahead of the stream cursor.

    Both coarse and fine seeking use the page structure and sequencing inherent to the Ogg format. All Ogg streams are fully seekable from creation; seekability is unaffected by truncation or missing data, and is tolerant of gross corruption. Seek operations are neither 'fuzzy' nor heuristic.

    Seeking without use of an index is a major point of the Ogg design. There two primary reasons why Ogg transport forgoes an index:

    1. An index is only marginally useful in Ogg for the complexity added; it adds no new functionality and seldom improves performance noticeably. Empirical testing shows that indexless interpolation search does not require many more seeks in practice than using an index would.
    2. 'Optional' indexes encourage lazy implementations that can seek only when indexes are present, or that implement indexless seeking only by building an internal index after reading the entire file beginning to end. This has been the fate of other containers that specify optional indexing.

    In addition, it must be possible to create an Ogg stream in a single pass. Although an optional index can simply be tacked on the end of the created stream, some software groups object to end-positioned indexes and claim to be unwilling to support indexes not located at the stream beginning.

    All this said, it's become clear that an optional index is a demanded feature. For this reason, the OggSkeleton now defines a proposed index.

    Simple multiplexing

    Ogg multiplexes streams by interleaving pages from multiple elementary streams into a multiplexed stream in time order. The multiplexed pages are not altered. Muxing an Ogg AV stream out of separate audio, video and data streams is akin to shuffling several decks of cards together into a single deck; the cards themselves remain unchanged. Demultiplexing is similarly simple (as the cards are marked).

    The goal of this design is to make the mux/demux operation as trivial as possible to allow live streaming systems to build and rebuild streams on the fly with minimal CPU usage and no additional storage or latency requirements.

    Continuous and Discontinuous Media

    Ogg streams belong to one of two categories, "Continuous" streams and "Discontinuous" streams.

    A stream that provides a gapless, time-continuous media type with a fine-grained timebase is considered to be 'Continuous'. A continuous stream should never be starved of data. Examples of continuous data types include broadcast audio and video.

    A stream that delivers data in a potentially irregular pattern or with widely spaced timing gaps is considered to be 'Discontinuous'. A discontinuous stream may be best thought of as data representing scattered events; although they happen in order, they are typically unconnected data often located far apart. One example of a discontinuous stream types would be captioning such as Ogg Kate. Although it's possible to design captions as a continuous stream type, it's most natural to think of captions as widely spaced pieces of text with little happening between.

    The fundamental reason for distinction between continuous and discontinuous streams concerns buffering.

    Buffering

    A continuous stream is, by definition, gapless. Ogg buffering is based on the simple premise of never allowing an active continuous stream to starve for data during decode; buffering works ahead until all continuous streams in a physical stream have data ready and no further.

    Discontinuous stream data is not assumed to be predictable. The buffering design takes discontinuous data 'as it comes' rather than working ahead to look for future discontinuous data for a potentially unbounded period. Thus, the buffering process makes no attempt to fill discontinuous stream buffers; their pages simply 'fall out' of the stream when continuous streams are handled properly.

    Buffering requirements in this design need not be explicitly declared or managed in the encoded stream. The decoder simply reads as much data as is necessary to keep all continuous stream types gapless and no more, with discontinuous data processed as it arrives in the continuous data. Buffering is implicitly optimal for the given stream. Because all pages of all data types are stamped with absolute timing information within the stream, inter-stream synchronization timing is always maintained without the need for explicitly declared buffer-ahead hinting.

    Codec metadata

    Ogg does not replicate codec-specific metadata into the mux layer in an attempt to make the mux and codec layer implementations 'fully separable'. Things like specific timebase, keyframing strategy, frame duration, etc, do not appear in the Ogg container. The mux layer is, instead, expected to query a codec through a centralized interface, left to the implementation, for this data when it is needed.

    Though modern design wisdom usually prefers to predict all possible needs of current and future codecs then embed these dependencies and the required metadata into the container itself, this strategy increases container specification complexity, fragility, and rigidity. The mux and codec code becomes more independent, but the specifications become logically less independent. A codec can't do what a container hasn't already provided for. Novel codecs are harder to support, and you can do fewer useful things with the ones you've already got (eg, try to make a good splitter without using any codecs. Such a splitter is limited to splitting at keyframes only, or building yet another new mechanism into the container layer to mark what frames to skip displaying).

    Ogg's design goes the opposite direction, where the specification is to be as simple, easy to understand, and 'proofed' against novel codecs as possible. When an Ogg mux layer requires codec-specific information, it queries the codec (or a codec stub). This trades a more complex implementation for a simpler, more flexible specification.

    Stream structure metadata

    The Ogg container itself does not define a metadata system for declaring the structure and interrelations between multiple media types in a muxed stream. That is, the Ogg container itself does not specify data like 'which steam is the subtitle stream?' or 'which video stream is the primary angle?'. This metadata still exists, but is stored by the Ogg container rather than being built into the Ogg container itself. Xiph specifies the 'Skeleton' metadata format for Ogg streams, but this decoupling of container and stream structure metadata means it is possible to use Ogg with any metadata specification without altering the container itself, or without stream structure metadata at all.

    Frame accurate absolute position

    Every Ogg page is stamped with a 64 bit 'granule position' that serves as an absolute timestamp for mux and seeking. A few nifty little tricks are usually also embedded in the granpos state, but we'll leave those aside for the moment (strictly speaking, they're part of each codec's mapping, not Ogg).

    As previously mentioned above, granule positions are mapped into absolute timestamps by the codec, rather than being a hard timestamp. This allows maximally efficient use of the available 64 bits to address every sample/frame position without approximation while supporting new and previously unknown timebase encodings without needing to extend or update the mux layer. When a codec needs a novel timebase, it simply brings the code for that mapping along with it. This is not a theoretical curiosity; new, wholly novel timebases were deployed with the adoption of both Theora and Dirac. "Rolling INTRA" (keyframeless video) also benefits from novel use of the granule position.

    Ogg stream arrangement

    Packets, pages, and bitstreams

    Ogg codecs place raw compressed data into packets. Packets are octet payloads containing the data needed for a single decompressed unit, eg, one video frame. Packets have no maximum size and may be zero length. They do not generally have any framing information; strung together, the unframed packets form a logical bitstream of codec data with no internal landmarks.

    Packets of raw codec data are not typically internally framed. When they are strung together into a stream without any container to provide framing, they lose their individual boundaries. Seek and capture are not possible within an unframed stream, and for many codecs with variable length payloads and/or early-packet termination (such as Vorbis), it may become impossible to recover the original frame boundaries even if the stream is scanned linearly from beginning to end.

    Logical bitstream packets are grouped and framed into Ogg pages along with a unique stream serial number to produce a physical bitstream. An elementary stream is a physical bitstream containing only a single logical bitstream. Each page is a self contained entity, although a packet may be split and encoded across one or more pages. The page decode mechanism is designed to recognize, verify and handle single pages at a time from the overall bitstream.

    The primary purpose of a container is to provide framing for raw packets, marking the packet boundaries so the exact packets can be retrieved for decode later. The container also provides secondary functions such as capture, timestamping, sequencing, stream identification and so on. Not all of these functions are represented in the diagram.

    In the Ogg container, pages do not necessarily contain integer numbers of packets. Packets may span across page boundaries or even multiple pages. This is necessary as pages have a maximum possible size in order to provide capture guarantees, but packet size is unbounded.

    Ogg Bitstream Framing specifies the page format of an Ogg bitstream, the packet coding process and elementary bitstreams in detail.

    Multiplexed bitstreams

    Multiple logical/elementary bitstreams can be combined into a single multiplexed bitstream by interleaving whole pages from each contributing elementary stream in time order. The result is a single physical stream that multiplexes and frames multiple logical streams. Each logical stream is identified by the unique stream serial number stamped in its pages. A physical stream may include a 'meta-header' (such as the Ogg Skeleton) comprising its own Ogg page at the beginning of the physical stream. A decoder recovers the original logical/elementary bitstreams out of the physical bitstream by taking the pages in order from the physical bitstream and redirecting them into the appropriate logical decoding entity.

    Multiple media types are mutliplexed into a single Ogg stream by interleaving the pages from each elementary physical stream.

    Ogg Bitstream Multiplexing specifies proper multiplexing of an Ogg bitstream in detail.

    Chaining

    Multiple Ogg physical bitstreams may be concatenated into a single new stream; this is chaining. The bitstreams do not overlap; the final page of a given logical bitstream is immediately followed by the initial page of the next.

    Each logical bitstream in a chain must have a unique serial number within the scope of the full physical bitstream, not only within a particular link or segment of the chain.

    Continuous and discontinuous streams

    Within Ogg, each stream must be declared (by the codec) to be continuous- or discontinuous-time. Most codecs treat all streams they use as either inherently continuous- or discontinuous-time, although this is not a requirement. A codec may, as part of its mapping, choose according to data in the initial header.

    Continuous-time pages are stamped by end-time, discontinuous pages are stamped by begin-time. Pages in a multiplexed stream are interleaved in order of the time stamp regardless of stream type. Both continuous and discontinuous logical streams are used to seek within a physical stream, however only continuous streams are used to determine buffering depth; because discontinuous streams are stamped by start time, they will always 'fall out' at the proper time when buffering the continuous streams. See 'Examples' for an illustration of the buffering mechanism.

    Multiplexing Requirements

    Multiplexing requirements within Ogg are straightforward. When constructing a single-link (unchained) physical bitstream consisting of multiple elementary streams:

    1. The initial header for each stream appears in sequence, each header on a single page. All initial headers must appear with no intervening data (no auxiliary header pages or packets, no data pages or packets). Order of the initial headers is unspecified. The 'beginning of stream' flag is set on each initial header.

    2. All auxiliary headers for all streams must follow. Order is unspecified. The final auxiliary header of each stream must flush its page.

    3. Data pages for each stream follow, interleaved in time order.

    4. The final page of each stream sets the 'end of stream' flag. Unlike initial pages, terminal pages for the logical bitstreams need not occur contiguously; indeed it may not be possible for them to do so.

    Each grouped bitstream must have a unique serial number within the scope of the physical bitstream.

    chaining and multiplexing

    Multiplexed and/or unmultiplexed bitstreams may be chained consecutively. Such a physical bitstream obeys all the rules of both chained and multiplexed streams. Each link, when unchained, must stand on its own as a valid physical bitstream. Chained streams do not mix or interleave; a new segment may not begin until all streams in the preceding segment have terminated.

    Codec Mapping Requirements

    Each codec is allowed some freedom in deciding how its logical bitstream is encapsulated into an Ogg bitstream (even if it is a trivial mapping, eg, 'plop the packets in and go'). This is the codec's mapping. Ogg imposes a few mapping requirements on any codec.

    1. The framing specification defines 'beginning of stream' and 'end of stream' page markers via a header flag (it is possible for a stream to consist of a single page). A correct stream always consists of an integer number of pages, an easy requirement given the variable size nature of pages.

    2. The first page of an elementary Ogg bitstream consists of a single, small 'initial header' packet that must include sufficient information to identify the exact CODEC type. From this initial header, the codec must also be able to determine its timebase and whether or not it is a continuous- or discontinuous-time stream. The initial header must fit on a single page. If a codec makes use of auxiliary headers (for example, Vorbis uses two auxiliary headers), these headers must follow the initial header immediately. The last header finishes its page; data begins on a fresh page.

      As an example, Ogg Vorbis places the name and revision of the Vorbis CODEC, the audio rate and the audio quality into this initial header. Vorbis comments and detailed codec setup appears in the larger auxiliary headers.

    3. Granule positions must be translatable to an exact absolute time value. As described above, the mux layer is permitted to query a codec or codec stub plugin to perform this mapping. It is not necessary for an absolute time to be mappable into a single unique granule position value.

    4. Codecs are not required to use a fixed duration-per-packet (for example, Vorbis does not). the mux layer is permitted to query a codec or codec stub plugin for the time duration of a packet.

    5. Although an absolute time need not be translatable to a unique granule position, a codec must be able to determine the unique granule position of the current packet using the granule position of a preceeding packet.

    6. Packets and pages must be arranged in ascending granule-position and time order.

    Examples

    [More to come shortly; this section is currently being revised and expanded]

    Below, we present an example of a multiplexed and chained bitstream:

    stream

    In this example, we see pages from five total logical bitstreams multiplexed into a physical bitstream. Note the following characteristics:

    1. Multiplexed bitstreams in a given link begin together; all of the initial pages must appear before any data pages. When concurrently multiplexed groups are chained, the new group does not begin until all the bitstreams in the previous group have terminated.

Pfeiffer Informational [Page 7] RFC 3533 OGG May 2003 The following diagram shows a schematic example of a media mapping using Ogg and grouped logical bitstreams: logical bitstream with packet boundaries ----------------------------------------------------------------- > | packet_1 | packet_2 | packet_3 | < ----------------------------------------------------------------- |segmentation (logically only) v packet_1 (5 segments) packet_2 (4 segs) p_3 (2 segs) ------------------------------ -------------------- ------------ .. |seg_1|seg_2|seg_3|seg_4|s_5 | |seg_1|seg_2|seg_3|| |seg_1|s_2 | .. ------------------------------ -------------------- ------------ | page encapsulation v page_1 (packet_1 data) page_2 (pket_1 data) page_3 (packet_2 data) ------------------------ ---------------- ------------------------ |H|------------------- | |H|----------- | |H|------------------- | |D||seg_1|seg_2|seg_3| | |D|seg_4|s_5 | | |D||seg_1|seg_2|seg_3| | ... |R|------------------- | |R|----------- | |R|------------------- | ------------------------ ---------------- ------------------------ | pages of | other --------| | logical ------- bitstreams | MUX | ------- | v page_1 page_2 page_3 ------ ------ ------- ----- ------- ... || | || | || | || | || | ... ------ ------ ------- ----- ------- physical Ogg bitstream In this example we take a snapshot of the encapsulation process of one logical bitstream. We can see part of that bitstream's subdivision into packets as provided by the codec. The Ogg encapsulation process chops up the packets into segments. The packets in this example are rather large such that packet_1 is split into 5 segments - 4 segments with 255 bytes and a final smaller one. Packet_2 is split into 4 segments - 3 segments with 255 bytes and a Pfeiffer Informational [Page 8] RFC 3533 OGG May 2003 final very small one - and packet_3 is split into two segments. The encapsulation process then creates pages, which are quite small in this example. Page_1 consists of the first three segments of packet_1, page_2 contains the remaining 2 segments from packet_1, and page_3 contains the first three pages of packet_2. Finally, this logical bitstream is multiplexed into a physical Ogg bitstream with pages of other logical bitstreams. 6. The Ogg page format A physical Ogg bitstream consists of a sequence of concatenated pages. Pages are of variable size, usually 4-8 kB, maximum 65307 bytes. A page header contains all the information needed to demultiplex the logical bitstreams out of the physical bitstream and to perform basic error recovery and landmarks for seeking. Each page is a self-contained entity such that the page decode mechanism can recognize, verify, and handle single pages at a time without requiring the overall bitstream. The Ogg page header has the following format: 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1| Byte +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | capture_pattern: Magic number for page start "OggS" | 0-3 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | version | header_type | granule_position | 4-7 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | 8-11 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | bitstream_serial_number | 12-15 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | page_sequence_number | 16-19 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | | CRC_checksum | 20-23 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | |page_segments | segment_table | 24-27 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ | ... | 28- +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ The LSb (least significant bit) comes first in the Bytes. Fields with more than one byte length are encoded LSB (least significant byte) first. Pfeiffer Informational [Page 9] RFC 3533 OGG May 2003 The fields in the page header have the following meaning: 1. capture_pattern: a 4 Byte field that signifies the beginning of a page. It contains the magic numbers: 0x4f 'O' 0x67 'g' 0x67 'g' 0x53 'S' It helps a decoder to find the page boundaries and regain synchronisation after parsing a corrupted stream. Once the capture pattern is found, the decoder verifies page sync and integrity by computing and comparing the checksum. 2. stream_structure_version: 1 Byte signifying the version number of the Ogg file format used in this stream (this document specifies version 0). 3. header_type_flag: the bits in this 1 Byte field identify the specific type of this page. * bit 0x01 set: page contains data of a packet continued from the previous page unset: page contains a fresh packet * bit 0x02 set: this is the first page of a logical bitstream (bos) unset: this page is not a first page * bit 0x04 set: this is the last page of a logical bitstream (eos) unset: this page is not a last page 4. granule_position: an 8 Byte field containing position information. For example, for an audio stream, it MAY contain the total number of PCM samples encoded after including all frames finished on this page. For a video stream it MAY contain the total number of video Pfeiffer Informational [Page 10] RFC 3533 OGG May 2003 frames encoded after this page. This is a hint for the decoder and gives it some timing and position information. Its meaning is dependent on the codec for that logical bitstream and specified in a specific media mapping. A special value of -1 (in two's complement) indicates that no packets finish on this page. 5. bitstream_serial_number: a 4 Byte field containing the unique serial number by which the logical bitstream is identified. 6. page_sequence_number: a 4 Byte field containing the sequence number of the page so the decoder can identify page loss. This sequence number is increasing on each logical bitstream separately. 7. CRC_checksum: a 4 Byte field containing a 32 bit CRC checksum of the page (including header with zero CRC field and page content). The generator polynomial is 0x04c11db7. 8. number_page_segments: 1 Byte giving the number of segment entries encoded in the segment table. 9. segment_table: number_page_segments Bytes containing the lacing values of all segments in this page. Each Byte contains one lacing value. The total header size in bytes is given by: header_size = number_page_segments + 27 [Byte] The total page size in Bytes is given by: page_size = header_size + sum(lacing_values: 1..number_page_segments) [Byte] 7. Security Considerations The Ogg encapsulation format is a container format and only encapsulates content (such as Vorbis-encoded audio). It does not provide for any generic encryption or signing of itself or its contained content bitstreams. However, it encapsulates any kind of content bitstream as long as there is a codec for it, and is thus able to contain encrypted and signed content data. It is also possible to add an external security mechanism that encrypts or signs an Ogg physical bitstream and thus provides content confidentiality and authenticity. As Ogg encapsulates binary data, it is possible to include executable content in an Ogg bitstream. This can be an issue with applications that are implemented using the Ogg format, especially when Ogg is used for streaming or file transfer in a networking scenario. As Pfeiffer Informational [Page 11] RFC 3533 OGG May 2003 such, Ogg does not pose a threat there. However, an application decoding Ogg and its encapsulated content bitstreams has to ensure correct handling of manipulated bitstreams, of buffer overflows and the like. 8.

Glossary of terms and abbreviations bos page: The initial page (beginning of stream) of a logical bitstream which contains information to identify the codec type and other decoding-relevant information. chaining (or sequential multiplexing): Concatenation of two or more complete physical Ogg bitstreams. eos page: The final page (end of stream) of a logical bitstream. granule position: An increasing position number for a specific logical bitstream stored in the page header. Its meaning is dependent on the codec for that logical bitstream and specified in a specific media mapping. grouping (or concurrent multiplexing): Interleaving of pages of several logical bitstreams into one complete physical Ogg bitstream under the restriction that all bos pages of all grouped logical bitstreams MUST appear before any data pages. lacing value: An entry in the segment table of a page header representing the size of the related segment. logical bitstream: A sequence of bits being the result of an encoded media stream. media mapping: A specific use of the Ogg encapsulation format together with a specific (set of) codec(s). (Ogg) packet: A subpart of a logical bitstream that is created by the encoder for that bitstream and represents a meaningful entity for the encoder, but only a sequence of bits to the Ogg encapsulation. (Ogg) page: A physical bitstream consists of a sequence of Ogg pages containing data of one logical bitstream only. It usually contains a group of contiguous segments of one packet only, but sometimes packets are too large and need to be split over several pages. physical (Ogg) bitstream: The sequence of bits resulting from an Ogg encapsulation of one or several logical bitstreams. It consists of a sequence of pages from the logical bitstreams with the restriction that the pages of one logical bitstream MUST come in their correct temporal order. Pfeiffer Informational [Page 13] RFC 3533 OGG May 2003 (Ogg) segment: The Ogg encapsulation process splits each packet into chunks of 255 bytes plus a last fractional chunk of less than 255 bytes.

Standards Track [Page 1] RFC 5334 Ogg Media Types September 2008 1. Introduction This document describes media types for Ogg, a data encapsulation format defined by the Xiph.Org Foundation for public use. Refer to "Introduction" in [RFC3533] and "Overview" in [Ogg] for background information on this container format. Binary data contained in Ogg, such as Vorbis and Theora, has historically been interchanged using the application/ogg media type as defined by [RFC3534]. This document obsoletes [RFC3534] and defines three media types for different types of content in Ogg to reflect this usage in the IANA media type registry, to foster interoperability by defining underspecified aspects, and to provide general security considerations. The Ogg container format is known to contain [Theora] or [Dirac] video, [Speex] (narrow-band and wide-band) speech, [Vorbis] or [FLAC] audio, and [CMML] timed text/metadata. As Ogg encapsulates binary data, it is possible to include any other type of video, audio, image, text, or, generally speaking, any time-continuously sampled data. While raw packets from these data sources may be used directly by transport mechanisms that provide their own framing and packet- separation mechanisms (such as UDP datagrams or RTP), Ogg is a solution for stream based storage (such as files) and transport (such as TCP streams or pipes). The media types defined in this document are needed to correctly identify such content when it is served over HTTP, included in multi-part documents, or used in other places where media types [RFC2045] are used. 2. Changes Since RFC 3534 o The type "application/ogg" is redefined. o The types "video/ogg" and "audio/ogg" are defined. o New file extensions are defined. o New Macintosh file type codes are defined. o The codecs parameter is defined for optional use. o The Ogg Skeleton extension becomes a recommended addition for content served under the new types. Goncalves, et al. Standards Track [Page 2] RFC 5334 Ogg Media Types September 2008 3. Conformance and Document Conventions The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14, [RFC2119] and indicate requirement levels for compliant implementations. Requirements apply to all implementations unless otherwise stated. An implementation is a software module that supports one of the media types defined in this document. Software modules may support multiple media types, but conformance is considered individually for each type. Implementations that fail to satisfy one or more "MUST" requirements are considered non-compliant. Implementations that satisfy all "MUST" requirements, but fail to satisfy one or more "SHOULD" requirements, are said to be "conditionally compliant". All other implementations are "unconditionally compliant". 4. Deployed Media Types and Compatibility The application/ogg media type has been used in an ad hoc fashion to label and exchange multimedia content in Ogg containers. Use of the "application" top-level type for this kind of content is known to be problematic, in particular since it obfuscates video and audio content. This document thus defines the media types, o video/ogg o audio/ogg which are intended for common use and SHOULD be used when dealing with video or audio content, respectively. This document also obsoletes the [RFC3534] definition of application/ogg and marks it for complex data (e.g., multitrack visual, audio, textual, and other time-continuously sampled data), which is not clearly video or audio data and thus not suited for either the video/ogg or audio/ogg types. Refer to the following section for more details. An Ogg bitstream generally consists of one or more logical bitstreams that each consist of a series of header and data pages packetising time-continuous binary data [RFC3533]. The content types of the logical bitstreams may be identified without decoding the header pages of the logical bitstreams through use of a [Skeleton] bitstream. Using Ogg Skeleton is REQUIRED for content served under Goncalves, et al. Standards Track [Page 3] RFC 5334 Ogg Media Types September 2008 the application/ogg type and RECOMMENDED for video/ogg and audio/ogg, as Skeleton contains identifiers to describe the different encapsulated data. Furthermore, it is RECOMMENDED that implementations that identify a logical bitstream that they cannot decode SHOULD ignore it, while continuing to decode the ones they can. Such precaution ensures backward and forward compatibility with existing and future data. These media types can optionally use the "codecs" parameter described in [RFC4281]. Codecs encapsulated in Ogg require a text identifier at the beginning of the first header page, hence a machine-readable method to identify the encapsulated codecs would be through this header. The following table illustrates how those header values map into strings that are used in the "codecs" parameter when dealing with Ogg media types. Codec Identifier | Codecs Parameter ----------------------------------------------------------- char[5]: 'BBCD\0' | dirac char[5]: '\177FLAC' | flac char[7]: '\x80theora' | theora char[7]: '\x01vorbis' | vorbis char[8]: 'CELT ' | celt char[8]: 'CMML\0\0\0\0' | cmml char[8]: '\213JNG\r\n\032\n' | jng char[8]: '\x80kate\0\0\0' | kate char[8]: 'OggMIDI\0' | midi char[8]: '\212MNG\r\n\032\n' | mng char[8]: 'PCM ' | pcm char[8]: '\211PNG\r\n\032\n' | png char[8]: 'Speex ' | speex char[8]: 'YUV4MPEG' | yuv4mpeg An up-to-date version of this table is kept at Xiph.org (see [Codecs]). Possible examples include: o application/ogg; codecs="theora, cmml, ecmascript" o video/ogg; codecs="theora, vorbis" o audio/ogg; codecs=speex Goncalves, et al. Standards Track [Page 4] RFC 5334 Ogg Media Types September 2008 5. Relation between the Media Types As stated in the previous section, this document describes three media types that are targeted at different data encapsulated in Ogg. Since Ogg is capable of encapsulating any kind of data, the multiple usage scenarios have revealed interoperability issues between implementations when dealing with content served solely under the application/ogg type. While this document does redefine the earlier definition of application/ogg, this media type will continue to embrace the widest net possible of content with the video/ogg and audio/ogg types being smaller subsets of it. However, the video/ogg and audio/ogg types take precedence in a subset of the usages, specifically when serving multimedia content that is not complex enough to warrant the use of application/ogg. Following this line of thought, the audio/ogg type is an even smaller subset within video/ogg, as it is not intended to refer to visual content. As such, the application/ogg type is the recommended choice to serve content aimed at scientific and other applications that require various multiplexed signals or streams of continuous data, with or without scriptable control of content. For bitstreams containing visual, timed text, and any other type of material that requires a visual interface, but that is not complex enough to warrant serving under application/ogg, the video/ogg type is recommended. In situations where the Ogg bitstream predominantly contains audio data (lyrics, metadata, or cover art notwithstanding), it is recommended to use the audio/ogg type. 6. Encoding Considerations Binary: The content consists of an unrestricted sequence of octets. Note: o Ogg encapsulated content is binary data and should be transmitted in a suitable encoding without CR/LF conversion, 7-bit stripping, etc.; base64 [RFC4648] is generally preferred for binary-to-text encoding. o Media types described in this document are used for stream based storage (such as files) and transport (such as TCP streams or pipes); separate types are used to identify codecs such as in real-time applications for the RTP payload formats of Theora [ThRTP] video, Vorbis [RFC5215], or Speex [SpRTP] audio, as well as for identification of encapsulated data within Ogg through Skeleton. Goncalves, et al. Standards Track [Page 5] RFC 5334 Ogg Media Types September 2008 7. Security Considerations Refer to [RFC3552] for a discussion of terminology used in this section. The Ogg encapsulation format is a container and only a carrier of content (such as audio, video, and displayable text data) with a very rigid definition. This format in itself is not more vulnerable than any other content framing mechanism. Ogg does not provide for any generic encryption or signing of itself or its contained bitstreams. However, it encapsulates any kind of binary content and is thus able to contain encrypted and signed content data. It is also possible to add an external security mechanism that encrypts or signs an Ogg bitstream and thus provides content confidentiality and authenticity. As Ogg encapsulates binary data, it is possible to include executable content in an Ogg bitstream. Implementations SHOULD NOT execute such content without prior validation of its origin by the end-user. Issues may arise on applications that use Ogg for streaming or file transfer in a networking scenario. In such cases, implementations decoding Ogg and its encapsulated bitstreams have to ensure correct handling of manipulated bitstreams, of buffer overflows, and similar issues. It is also possible to author malicious Ogg bitstreams, which attempt to call for an excessively large picture size, high sampling-rate audio, etc. Implementations SHOULD protect themselves against this kind of attack. Ogg has an extensible structure, so that it is theoretically possible that metadata fields or media formats might be defined in the future which might be used to induce particular actions on the part of the recipient, thus presenting additional security risks. However, this type of capability is currently not supported in the referenced specification. Implementations may fail to implement a specific security model or other means to prevent possibly dangerous operations. Such failure might possibly be exploited to gain unauthorized access to a system or sensitive information; such failure constitutes an unknown factor and is thus considered out of the scope of this document. Goncalves, et al. Standards Track [Page 6] RFC 5334 Ogg Media Types September 2008 8. Interoperability Considerations The Ogg container format is device-, platform-, and vendor-neutral and has proved to be widely implementable across different computing platforms through a wide range of encoders and decoders. A broadly portable reference implementation [libogg] is available under the revised (3-clause) BSD license, which is a Free Software license. The Xiph.Org Foundation has defined the specification, interoperability, and conformance and conducts regular interoperability testing. The use of the Ogg Skeleton extension has been confirmed to not cause interoperability issues with existing implementations. Third parties are, however, welcome to conduct their own testing. 9. IANA Considerations In accordance with the procedures set forth in [RFC4288], this document registers two new media types and redefines the existing application/ogg as defined in the following section. 10.

Content served under the "audio/ogg" type SHOULD have an Ogg Skeleton logical bitstream when using the default .oga file extension. The .ogg and .spx file extensions indicate a specialization that requires no Skeleton due to backward compatibility concerns with existing implementations. In particular, .ogg is used for Ogg files that contain only a Vorbis bitstream, while .spx is used for Ogg files that contain only a Speex bitstream. Author: See "Authors' Addresses" section.

    The Ogg Skeleton Metadata Bitstream

    Overview

    Ogg Skeleton provides structuring information for multitrack Ogg files. It is compatible with Ogg Theora and provides extra clues for synchronization and content negotiation such as language selection.

    Ogg is a generic container format for time-continuous data streams, enabling interleaving of several tracks of frame-wise encoded content in a time-multiplexed manner. As an example, an Ogg physical bitstream could encapsulate several tracks of video encoded in Theora and multiple tracks of audio encoded in Speex or Vorbis or FLAC at the same time. A player that decodes such a bitstream could then, for example, play one video channel as the main video playback, alpha-blend another one on top of it (e.g. a caption track), play a main Vorbis audio together with several FLAC audio tracks simultaneously (e.g. as sound effects), and provide a choice of Speex channels (e.g. providing commentary in different languages). Such a file is generally possible to create with Ogg, it is however not possible to generically parse such a file, seek on it, understand what codecs are contained in such a file, and dynamically handle and play back such content.

    Ogg does not know anything about the content it carries and leaves it to the media mapping of each codec to declare and describe itself. There is no meta information available at the Ogg level about the content tracks encapsulated within an Ogg physical bitstream. This is particularly a problem if you don't have all the decoder libraries available and just want to parse an Ogg file to find out what type of data it encapsulates (such as the "file" command under *nix to determine what file it is through magic numbers), or want to seek to a temporal offset without having to decode the data (such as on a Web server that just serves out Ogg files and parts thereof).

    Ogg Skeleton is being designed to overcome these problems. Ogg Skeleton is a logical bitstream within an Ogg stream that contains information about the other encapsulated logical bitstreams. For each logical bitstream it provides information such as its media type, and explains the way the granulepos field in Ogg pages is mapped to time.

    Ogg Skeleton is also designed to allow the creation of substreams from Ogg physical bitstreams that retain the original timing information. For example, when cutting out the segment between the 7th and the 59th second of an Ogg file, it would be nice to continue to start this cut out file with a playback time of 7 seconds and not of 0. This is of particular interest if you're streaming this file from a Web server after a query for a temporal subpart such as in http://example.com/video.ogv?t=7-59

    Specification

    How to describe the logical bitstreams within an Ogg container?

    The following information about a logical bitstream is of interest to contain as meta information in the Skeleton:

    • the serial number: it identifies a content track
    • the mime type: it identifies the content type
    • other generic name-value fields that can provide meta information such as the language of a track or the video height and width
    • the number of header packets: this informs a parser about the number of actual header packets in an Ogg logical bitstream
    • the granule rate: the granule rate represents the data rate in Hz at which content is sampled for the particular logical bitstream, allowing to map a granule position to time by calculating "granulepos / granulerate"
    • the preroll: the number of past content packets to take into account when decoding the current Ogg page, which is necessary for seeking (vorbis has generally 2, speex 3)
    • the granuleshift: the number of lower bits from the granulepos field that are used to provide position information for sub-seekable units (like the keyframe shift in theora)
    • a basetime: it provides a mapping for granule position 0 (for all logical bitstreams) to a playback time; an example use: most content in professional analog video creation actually starts at a time of 1 hour and thus adding this additional field allows them retain this mapping on digitizing their content
    • a UTC time: it provides a mapping for granule position 0 (for all logical bitstreams) to a real-world clock time allowing to remember e.g. the recording or broadcast time of some content

    How to allow the creation of substreams from an Ogg physical bitstream?

    When cutting out a subpart of an Ogg physical bitstream, the aim is to keep all the content pages intact (including the framing and granule positions) and just change some information in the Skeleton that allows reconstruction of the accurate time mapping. When remultiplexing such a bitstream, it is necessary to take into account all the different contained logical bitstreams. A given cut-in time maps to several different byte positions in the Ogg physical bitstream because each logical bitstream has its relevant information for that time at a different location. In addition, the resolution of each logical bitstream may not be high enough to accommodate for the given cut-in time and thus there may be some surplus information necessary to be remuxed into the new bitstream.

    The following information is necessary to be added to the Skeleton to allow a correct presentation of a subpart of an Ogg bitstream:

    • the presentation time: this is the actual cut-in time and all logical bitstreams are meant to start presenting from this time onwards, not from the time their data starts, which may be some time before that (because this time may have mapped right into the middle of a packet, or because the logical bitstream has a preroll or a keyframe shift)
    • the basegranule: this represents the granule number with which this logical bitstream starts in the remuxed stream and provides for each logical bitstream the accurate start time of its data stream; this information is necessary to allow correct decoding and timing of the first data packets contained in a logcial bitstream of a remuxed Ogg stream

    Ogg Skeleton version 3.0 Format Specification

    Adding the above information into an Ogg bitstream without breaking existing Ogg functionality and code requires the use of a logical bitstream for Ogg Skeleton. This logical bitstream may be ignored on decoding such that existing players can still continue to play back Ogg files that have a Skeleton bitstream. Skeleton enriches the Ogg bitstream to provide meta information about structure and content of the Ogg bitstream.

    The Skeleton logical bitstream starts with an ident header that contains information about all of the logical bitstreams and is mapped into the Skeleton bos page. The first 8 bytes provide the magic identifier "fishead\0". After the fishead follows a set of secondary header packets, each of which contains information about one logical bitstream. These secondary header packets are identified by an 8 byte code of "fisbone\0". The Skeleton logical bitstream has no actual content packets. Its eos page is included into the stream before any data pages of the other logical bitstreams appear and contains a packet of length 0.

    The fishead ident header looks as follows:

    
  0                   1                   2                   3

    The version fields provide version information for the Skeleton track, currently being 3.0 (the number having evolved within the Annodex project).

    Presentation time and basetime are specified as a rational number, the denominator providing the temporal resolution at which the time is given (e.g. to specify time in milliseconds, provide a denominator of 1000).

    The fisbone secondary header packet looks as follows:

    
  0                   1                   2                   3

    The mime type is provided as a message header field specified in the same way that HTTP header fields are given (e.g. "Content-Type: audio/vorbis"). Further meta information (such as language and screen size) are also included as message header fields. The offset to the message header fields at the beginning of a fisbone packet is included for forward compatibility - to allow further fields to be included into the packet without disrupting the message header field parsing.

    The granule rate is again given as a rational number in the same way that presentation time and basetime were provided above.

    A further restriction on how to encapsulate Skeleton into Ogg is proposed to allow for easier parsing:

    • there can only be one Skeleton logical bitstream in a Ogg bitstream
    • the Skeleton bos page is the very first bos page in the Ogg stream such that it can be identified straight away and decoders don't get confused about it being e.g. Ogg Vorbis without this meta information
    • the bos pages of all the other logical bistreams come next (a requirement of Ogg)
    • the secondary header pages of all logical bitstreams come next, including Skeleton's secondary header packets
    • the Skeleton eos page end the control section of the Ogg stream before any content pages of any of the other logical bitstreams appear
