SoundSourceMP3: Based on abandoned libraries libid3tag and libmad.
SoundSourceM4A: Based on abandoned (libmp4v2) and almost abandoned (libfaad2) libraries. Already requires an ugly workaround.
SoundSourceSndfile: Is well maintained, has a simple API and is already used as a fallback. Currently the primary SoundSource for AIFF and WAV. No offset issues expected when switching to FFmpeg.
SoundSourceWv: Minor maintenance burden, but otherwise does not hurt. The API is simple enough to keep it.
SoundSourceFLAC/SoundSourceOggVorbis/SoundSourceOpus: Cannot be replaced by FFmpeg!!
SoundSourceCore Audio: Unmaintained due to lack of macOS contributors. Already requires an API adapter since the last refactoring.
SoundSourceMedi aFoundation: Unmaintained due to lack of Windows contributors and buggy (https:/ /bugs.launchpad .net/mixxx/ +bug/1899242)
