Comment (by devans@…):

 Replying to [comment:18 mojca@…]:
 > The latest release of `xmms2` is more than 4 years old (from 2011). The
 problems have most likely been fixed in the devel version (see
 https://git.xmms2.org/xmms2/xmms2-devel/), but I don't see any sign of a
 new release. We should probably open a separate ticket for that.

 As you say, it looks like the hard part of updating this port (moving from
 avcodec_decode_audio3 to avcodec_decode_audio4 which involves moving from
 fixed buffers to AVFrames) has been already done upstream as part of a
 cleanup of deprecations.  The changes are very localized to a specific
 plugin, so I'm working on just back porting the appropriate changes (as
 patches) along with any residual cleanup necessary.

 This should fix the ffmpeg compatibility issues without getting into a
 bigger can of worms having to do with the updating the program in its
 entirety.  Since there hasn't been a new release in a long time it would
 probably be wise to confer with the upstream developers to see if they
 would be willing to make one that they think is relatively stable.
