Soundsource Refactor Merge

Reducing Number of Input Libraries

Possibly migrating to a single file decoding solution such as libavformat.

Pros

• Reduces library dependency count
• Increases playable formats
• I specifically want m4a/aac playback in our next version - Adam d
• User can recompile library to add new format support to an old version of mixxx

Cons

• Lots of work to make the change
• All our eggs are in one basket

Possible Libraries

• libsox
• supports nearly every format known to man
• can write many of them as well (for recording your set)
• has built-in effects processing
• libavformat/libavcodec (the library used by ffmpeg and mplayer)
• support lots of formats
• support utf8
• xine-lib
• supports lots of formats and is extensible
• use to play audio from (multiplexed) video files
• future VJ support?
• It's not totally cross-platform yet but progress is ongoing: http://www.xine-project.org/about
• gstreamer
• used by Songbird
• plugins allow more formats (QuickTime, WMA, FFMPEG, etc.)
