FishSound 0.9.0 Release
libfishsound provides a simple programming interface for decoding and
encoding audio data using Xiph.Org codecs (FLAC, Speex and Vorbis).
This release is available as a source tarball at:
New in this release
This release introduces support for the FLAC lossless audio codec,
originally contributed by Tobias Gehrig.
* Encoding and decoding of the PCM audio and "Vorbiscomment" metadata
packets is supported for FLAC streams in Ogg.
* The documentation and test suite have been updated for FLAC.
* The decoder example now handles Ogg files containing multiple
logical bitstreams; it simply extracts the first audio track.
This demonstrates how to decode audio from a video file, or
one track of a multitrack audio file.
* Updated shared version info to 4:0:3
One goal of this release is to allow playback of videos encoded with
the Theora and FLAC codecs in liboggplay+Mozilla. If you are testing
against svn, please use the following branch:
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.
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.
Full documentation of the FishSound API, customization and installation,
and complete examples of Ogg FLAC, Speex and Ogg Vorbis decoding and encoding
are provided in the source tarball, and can be read online at:
FishSound is Free Software, available under a BSD-style license.
