The program gst123 is designed to be a more flexible command line player in the spirit of ogg123 and mpg123, based on GStreamer. It plays all file formats supported by GStreamer, so if you have audio/video collections which contain different file formats, like flac, ogg and mp3, you can use gst123 to play all your audio/video files.
FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file.
FLAC stands out as the fastest and most widely suppo
minor feature: -- General:
Fix undefined behaviour using GCC/Clang UBSAN (erikd).
General hardening via fuzz testing with AFL (erikd and others).
General code improvements (lvqcl, erikd and others).
Add FLAC in MP4 specification docs (Ralph Giles).
MSVS build cleanups (lvqcl).
Fix some cppcheck warnings (erikd).
Assume all currently used OSes support SSE2.
-- flac:
Fix potential infinite loop on flac-to-flac conversion (erikd).
Add WAVEFORMATEXTENSIBLE to WAV (as needed) when decoding (lvqcl).
Only write vorbis-comments if they are non-empty.
Error out if decoding RAW with bits != (8 16 24).
-- metaflac:
Add --scan-replay-gain option.
-- build system:
Fixes for MSVC and Makefile.lite build systems.
-- libraries:
CPU detection cleanup and fixes (Julian Calaby, erikd and lvqcl).
Fix two stream decoder bugs (Max Kellermann).
Fix a NULL dereference bug (on a malformed file).
Changed the LPC order guess for a slight compression improvement, particularly for classical music (Martijn van Beurden).
Improved encoding speed on older Intel CPUs.
Fixed a seeking bug when decoding certain files (Miroslav Lichvar).
Put an upper bound (32768) on the number of seek points.
Fix potential memory leaks.
Support 64bit brword/bwword allowing FLAC__BYTES_PER_WORD to be set to 8 (disabled by default).
Fix an out-of-bounds heap read.
Win32: Only use large buffers when writing to disk.
 Mixed audio codec lossless
ICEcast is a audio/video streaming media server. Which supports Ogg Vorbis, Ogg Theora, FLAC over Ogg, Opus, Speex in Ogg, WebM and MP3 audio streams. It's widely used for setting up public internet radio stations, or local jukebox servers. ICEcast is flexible and extensible with new media formats and functionality.
Oggify is a command-line tool to convert between different audio formats. It's foremost intended to manage OGG Vorbis based collections, but also supports FLAC, or MP3 for older players, ALAC and MP4 on Mac OS X.
mp3splt breaks up MP3, OGG Vorbis and FLAC audio files without decoding. It doesn't require pre-defined timestamps but CUE or CDDB meta info, or by detecting album or stream audio silence breaks. It's a command-line tool, but a Gtk+ interface is also available.
