SOLVED Possible fix for building mplayer with ffmpeg-4.4

Can anybody confirm this? I build a rather reduced version for use with a script, and I don't use S/PDIF according to alsamixer. Anyway, mplayer seems to work with ffmpeg-4.4, but the build fails. Using "--disable-decoder=spdif --disable-encoder=spdif" does not work, same with {,de}muxer.

Re: SOLVED Possible fix for building mplayer with ffmpeg-4.4

The correct fix should be this:

$ svn log -c r38199 svn://svn.mplayerhq.hu/mplayer/trunk
------------------------------------------------------------------------
r38199 | reimar | 2020-11-01 16:07:44 +0100 (So, 01. Nov 2020) | 4 Zeilen

ad_spdif: Use avformat_free_context to free context.

This avoids memleaks and in newest FFmpeg versions also
compile errors.

Re: SOLVED Possible fix for building mplayer with ffmpeg-4.4

Thanks!

All I had to do was update the revision to 38199. No patch required. The package should be updated to use that revision, it is still on 38157.
