MPlayer currently fails to build with FFmpeg versions after the recent major bumps.

We are working on this at the moment.

An intial attempt to fix mplayer (not mencoder) was sent by Reimar on the developer list:

​https://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2021-April/073982.html

[beastd]

make mplayer should be working again after MPlayer SVN r38306 .

Build of mencoder is still failing. There is a patch for muxer_lavf on the mplayer-dev-eng mailing list, so ve_lavc is the last thing left to fix to make mencoder build again.

[beastd]

The build should be fixed since MPlayer SVN r38312 .

If the build still fails, feel free to re-open this ticket.

Thanks for reporting this issue.
