FishSound, the sound of fish!
-----------------------------
Full documentation is available in doc/fishsound/html/index.html,
or online at http://www.annodex.net/software/libfishsound/html/
Updates are available online at the FishSound homepage:
http://www.annodex.net/software/libfishsound/
libfishsound provides a simple programming interface for decoding and
encoding audio data using Xiph.Org codecs (FLAC, Speex and Vorbis).
libfishsound by itself is designed to handle raw codec streams from a
lower level layer such as UDP datagrams. When these codecs are used in
files, they are commonly encapsulated in Ogg to produce Ogg FLAC, Speex
and Ogg Vorbis files.
libfishsound is a wrapper around the existing codec libraries and provides
a consistent, higher-level programming interface. It has been designed for
use in a wide variety of applications; it has no direct dependencies on
Ogg encapsulation, though it is most commonly used in conjunction with
liboggz to decode or encode FLAC, Speex or Vorbis audio tracks in Ogg files,
including Ogg Theora and Annodex.
This source tarball
-------------------
FishSound has been developed and tested on GNU/Linux, Darwin/MacOSX and
Win32. It probably also works on other Unix-like systems via GNU autoconf.
For Win32: nmake Makefiles, Visual Studio .NET 2003 solution files and
Visual C++ 6.0 workspace files are all provided in the source distribution.
Details for building with GNU autotools are in the file INSTALL. Read the
file README.win32 for installing under MS Windows.
src/libfishsound/ the library source code.
src/examples/ example tools for programming with libfishsound.
include/ the libfishound include files that will be installed
into the system include directory.
doc/ documentation for libfishsound. The subdirectory
doc/libfishsound is autocreated by doxygen from
comments contained in <fishsound/fishsound.h>
win32/ files necessary to compile under MS Windows.

/** \file
* Encoding and decoding of comments.
*
* Vorbis and Speex bitstreams
* use a comment format called "Vorbiscomment", defined
* <a href="http://www.xiph.org/ogg/vorbis/doc/v-comment.html">here</a>.
* Many standard comment names (such as TITLE, COPYRIGHT and GENRE) are
* defined in that document.
*
* The following general features of Vorbiscomment are relevant to this API:
* - Each stream has one comment packet, which occurs before any encoded
* audio data in the stream.
* - When encoding, FishSound will generate the comment block and pass it
* to the encoded() callback in sequence, just like any other packet.
* Hence, all comments must be set before any call to fish_sound_encode_*().
* - When decoding, FishSound will decode the comment block before calling
* the first decoded() callback. Hence, retrieving comment data is possible
* from as soon as the decoded() callback is first called.
*
* Each comment block contains one Vendor string, which can be retrieved
* with fish_sound_comment_get_vendor(). When encoding, this string is
* effectively fixed by the codec libraries; it cannot be set by the
* application.
*
* The rest of a comment block consists of \a name = \a value pairs, with
* the following restrictions:
* - Both the \a name and \a value must be non-empty
* - The \a name is case-insensitive and must consist of ASCII within the
* range 0x20 to 0x7D inclusive, 0x3D ('=') excluded.
* - The \a name is not unique; multiple entries may exist with equivalent
* \a name within a Vorbiscomment block.
* - The \a value may be any UTF-8 string.
*
* \section comments_get Retrieving comments
*
* FishSound contains API methods to iterate through all comments associated
* with a FishSound* handle (fish_sound_comment_first() and
* fish_sound_comment_next(), and to iterate through comments matching a
* particular name (fish_sound_comment_first_byname() and
* fish_sound_comment_next_byname()). Given that multiple comments may exist
* with the same \a name, you should not use
* fish_sound_comment_first_byname() as a simple "get" function.
*
* \section comments_set Encoding comments
*
* For encoding, FishSound contains API methods for adding comments
* (fish_sound_comment_add() and fish_sound_comment_add_byname()
* and for removing comments
* (fish_sound_comment_remove() and fish_sound_comment_remove_byname()).

* \section intro FishSound, the sound of fish!
*
* This is the documentation for the FishSound C API. FishSound provides
* a simple programming interface for decoding and encoding audio data
* using Xiph.Org codecs (FLAC, Speex and Vorbis).
*
* libfishsound by itself is designed to handle raw codec streams from

* <em>Ogg FLAC</em>, <em>Speex</em> and <em>Ogg Vorbis</em> files.
* Example C programs using
* <a href="http://www.annodex.net/software/liboggz/">liboggz</a> to
* read and write these files are provided in the libfishsound sources.

/** \defgroup about About
*
* \section design Design
* libfishsound provides a simple programming interface for decoding and
* encoding audio data using codecs from
* <a href="http://www.xiph.org/">Xiph.Org</a>.
*
* libfishsound by itself is designed to handle raw codec streams from
* a lower level layer such as UDP datagrams.
* When these codecs are used in files, they are commonly encapsulated in
* <a href="http://www.xiph.org/ogg/">Ogg</a> to produce
* <em>Ogg FLAC</em>, <em>Speex</em> and <em>Ogg Vorbis</em> files.
* Example C programs using
* <a href="http://www.annodex.net/software/liboggz/">liboggz</a> to
* read and write these files are provided in the libfishsound sources.
*
* libfishsound is implemented as a wrapper around the existing codec
* libraries and provides a consistent, higher-level programming
* interface. The motivation for this is twofold: to simplify the task
* of developing application software that supports these codecs,
* and to ensure that valid codec streams are generated.
*
* \section history History
* libfishsound was designed and developed by Conrad Parker on the
* weekend of October 18-19 2003. Previously the author had implemented
* Vorbis and Speex support in the following software:
* - <a href="http://www.metadecks.org/software/sweep/">Sweep</a>, a
* digital audio editor with decoding and GUI control of all encoding
* options of Vorbis and Speex
* - Speex support in the <a href="http://www.xinehq.org/">xine</a>
* multimedia player
* - Vorbis and Speex importers for
* <a href="http://www.annodex.net/software/libannodex/">libannodex</a>,
the basic library for reading and writing
* <a href="http://www.annodex.net/">Annodex.net</a> media files.
*
* The implementation of libfishsound draws heavily on these sources, and
* in turn the original example sources of libvorbis and libvorbisenc by
* Monty, and libspeex by Jean-Marc Valin.
*
* The naming of libfishsound reflects both the Xiph.Org logo and
* the author's reputation as a dirty, smelly old fish.
*
* \section limitations Limitations
*
* libfishsound has been designed to accomodate the various decoding and
* encoding styles required by a wide variety of software. However, as it
* is an abstraction of the underlying libvorbis, libvorbisenc and libspeex
* libraries, it may not be possible to implement some low-level techniques
* that these libraries enable, such as parallelization of Vorbis sub-block
* decoding. Nevertheless it is expected that libfishsound is a useful
* API for most software requiring Vorbis or Speex support, including most
* applications the author has encountered.
*
* \section acknowledgements Acknowledgements
* Much of the API design follows the style of
* <a href="http://www.zip.com.au/~erikd/libsndfile/">libsndfile</a>.
* The author would like to thank Erik de Castro Lopo for feedback on the
* design of libfishsound.

/** \defgroup configuration Configuration
*
* \section platforms Platform-specific configuration
*
* FishSound can be configured on most platforms using the GNU autoconf
* ./configure system described below.
*
* For Win32, see the \link win32 README.win32 \endlink section. You will
* need to edit <tt>win32/config.h</tt> by hand to achieve the customizations
* described below.
*
* \section ./configure ./configure
*
* It is possible to customize the functionality of libfishsound
* by using various ./configure flags when
* building it from source; for example you can build a smaller
* version of libfishsound to only decode or encode, or and you can
* choose to disable support for a particular codec.
* By default, both decoding and encoding support is built for all
* codecs found on the system.
*
* For general information about using ./configure, see the file
* \link install INSTALL \endlink
*
* \subsection no_encode Removing encoding support
*
* Configuring with \a --disable-encode will remove all support for encoding:
* - All internal encoding related functions will not be built
* - Any attempt to call fish_sound_new() with \a mode == FISH_SOUND_ENCODE
* will fail, returning NULL
* - Any attempt to call fish_sound_encode_*() will return
* FISH_SOUND_ERR_DISABLED
* - The resulting library will not be linked against libvorbisenc
*
* \subsection no_decode Removing decoding support
*
* Configuring with \a --disable-decode will remove all support for decoding:
* - All internal decoding related functions will not be built
* - Any attempt to call fish_sound_new() with \a mode == FISH_SOUND_DECODE
* will fail, returning NULL
* - Any attempt to call fish_sound_decode() will return
* FISH_SOUND_ERR_DISABLED
*
* \subsection no_flac Removing FLAC support
*
* Configuring with \a --disable-flac will remove all support for FLAC:
* - All internal FLAC related functions will not be built
* - Any attempt to call fish_sound_new() with \a mode == FISH_SOUND_ENCODE
* and \a fsinfo->format == FISH_SOUND_FLAC will fail, returning NULL
* - The resulting library will not be linked against libFLAC
*
* \subsection no_speex Removing Speex support
*
* Configuring with \a --disable-speex will remove all support for Speex:
* - All internal Speex related functions will not be built
* - Any attempt to call fish_sound_new() with \a mode == FISH_SOUND_ENCODE
* and \a fsinfo->format == FISH_SOUND_SPEEX will fail, returning NULL
* - The resulting library will not be linked against libspeex
*
* \subsection no_vorbis Removing Vorbis support
*
* Configuring with \a --disable-vorbis will remove all support for Vorbis:
* - All internal Vorbis related functions will not be built
* - Any attempt to call fish_sound_new() with \a mode == FISH_SOUND_ENCODE
* and \a fsinfo->format == FISH_SOUND_VORBIS will fail, returning NULL
* - The resulting library will not be linked against libvorbis or libvorbisenc
*
* \subsection summary Configuration summary

* (Note that if your application requires FLAC support, you should check
* for a version of fishsound >= 0.9.0).
*
* If libfishsound is found, HAVE_FISHSOUND will be set to "yes", and
* the autoconf variables FISHSOUND_CFLAGS and FISHSOUND_LIBS will
* be set appropriately.
*
* \section pkg-config Determining compiler options with pkg-config
*
* If you are not using GNU autoconf in your project, you can use the
* pkg-config tool directly to determine the correct compiler options.
*
<pre>
FISHSOUND_CFLAGS=`pkg-config --cflags fishsound`
FISHSOUND_LIBS=`pkg-config --libs fishsound`

* \section general General usage
*
* All access is managed via a FishSound* handle. This is instantiated

* reset the internal codec state.
*
* \section decoding Decoding
*
* libfishsound provides callback based decoding: you feed it encoded audio
* data, and it will call your callback with decoded PCM. A more detailed
* explanation and a full example of decoding Ogg FLAC, Speex and Ogg Vorbis
* files is provided in the \link decode Decoding audio data \endlink section.

/** \defgroup decode Decoding audio data
*
* To decode audio data using libfishsound:
*
* - create a FishSound* object with mode FISH_SOUND_DECODE. fish_sound_new()
* will return a new FishSound* object, initialised for decoding, and the
* FishSoundInfo structure will be cleared.
* - provide a FishSoundDecoded_* callback for libfishsound to call when it has
* decoded audio.
* - (optionally) specify whether you want to receive interleaved or
* per-channel PCM data, using a fish_sound_set_interleave().
* The default is for per-channel (non-interleaved) PCM.
* - feed encoded audio data to libfishsound via fish_sound_decode().
* libfishsound will decode the audio for you, calling the FishSoundDecoded_*
* callback you provided earlier each time it has a block of audio ready.
* - when finished, call fish_sound_delete().
*
* This procedure is illustrated in src/examples/fishsound-decode.c.
* Note that this example additionally:
* - uses <a href="http://www.annodex.net/software/liboggz/">liboggz</a> to
* demultiplex audio data from an Ogg encapsulated FLAC, Speex or Vorbis
* stream. The step of feeding encoded data to libfishsound is done within
* the OggzReadPacket callback.
* - uses <a href="http://www.mega-nerd.com/libsndfile/">libsndfile</a> to

OggPlay: a library for playing Ogg multimedia
Overview
--------
The current version of the plugin is still under development therefore
the setup requires manual installation of the plugin. For more information,
see also:
http://wiki.xiph.org/index.php/OggPlay
Dependencies
------------
For the core library (liboggplay), you need
* libogg, libvorbis, libtheora, optionally libspeex -- from http://www.xiph.org/
svn co http://svn.xiph.org/trunk/ogg/ ogg
svn co http://svn.xiph.org/trunk/vorbis/ vorbis
svn co http://svn.xiph.org/trunk/theora/ theora
* liboggz and libfishsound -- from svn.annodex.net:
git clone git://git.xiph.org/liboggz.git
git clone git://git.xiph.org/libfishsound.git
Optionally, for Kate stream support, you need
* libkate -- from http://libkate.googlecode.com/
To render Kate streams as video overlays, you need
* libtiger -- from http://libtiger.googlecode.com/
Note that libtiger needs Pango and Cairo:
* Pango -- http://www.pango.org/
* Cairo -- http://cairographics.com/
See the README files associated with these libraries for installation
instructions.
To build src/examples/glut-player, you need:
* The core liboggplay dependencies (listed above)
* GLUT -- see http://www.opengl.org/resources/libraries/
To build src/examples/dump-all-streams, you need:
* The core liboggplay dependencies (listed above)
* libsndfile -- from http://www.mega-nerd.com/libsndfile/
To build src/tools/oggplay-dump-first-frame, you need:
* The core liboggplay dependencies (listed above)
* Imlib2 -- from your distribution or from
http://sourceforge.net/project/showfiles.php?group_id=2&package_id=11130
On Debian, the required packages for all these additional libraries are:
g++ libogg-dev libvorbis-dev libspeex-dev libtheora-dev libsndfile1-dev
libimlib2-dev libglut-dev
Compile and Install liboggplay
------------------------------
./autogen.sh
./configure
make && make install

The source from this directory was copied from the liboggplay svn
source using the update.sh script. The only changes made were those
applied by update.sh and the addition/upate of Makefile.in files for
the Mozilla build system.
git://git.xiph.org/liboggplay.git
The git commit ID used was 404316e5957370b3c854a86910c237c90746c325.
The following local patches have been applied:
endian: pick up NSPR's little/big endian defines in oggplay's config.h.
bug481921: fix a crash in oggplay_callback_info_prepare().
aspect-ratio: Adds oggplay_get_video_aspect_ratio, used for bug 480058.
bug493678.patch: fix for infinite loop in oggplay_step_decode. See bug 493678.
seek_to_key_frame.patch: Adds oggplay_seek_to_keyframe(), as per bug 463358.
oggplay_os2.patch: Bug 448918 - add OS/2 support (this patch should be
removed when OS/2 support is added upstream)
bug496529.patch: Fix bug 496529.
bug500311.patch: Fix crash during decoder initialization.
faster_seek.patch: Fix for bug 501031, make seeking faster over HTTP.
fix-17ef4ca82df28.patch: Fix oggplay_callback_predetected() to return
value interpreted as success upon success.
Fixes liboggplay changeset 17ef4ca82df28.
handle-read-errors.patch: Make oggplay_initialise() handle closing of stream
while reading. Prevents infinite loop. Further fix
to 17ef4ca82df28.
bug515217.patch: Fix crash where presentation thread releases a buffer just
before decode thread tries to set that buffer as the last at EOF.
bug504843.patch: Abort when decoding video excessively large video frames.
fishsound_reset.patch: Fixes bug 516323.
bug520493.patch: Ensure liboggplay returns data when all tracks
are deactivated when a callback reaches EOF.
bug523816.patch: Correct CMML data buffer size calculation.

commit 199a8cea6c4fd6d765254e7a384ac9df21ee2656
Author: Viktor Gal <viktor.gal@maeth.com>
Date: Fri May 8 15:44:51 2009 +1000
In the commit of 34c82de a bug was introduced in 'oggplay_data_handle_audio_data' function:
the number of samples in the record was not the correct value! The value of it
was incorrectly the size of the samples in the record.

Isaiah chips).
In the (unlikely) event a future processor uses bits 18, 19, 30, or 31
