Same with ffmpeg builds, and same in win64 version.
ffmpeg from different sources works ok, but I like MPLAYER...

FFmpeg has no AV1 support on its own, you'd need to ask the people providing the builds to add a AV1 decoder library (or if you build yourself provide a libdav1d for configure to find).

IIRC Sherpya added AV1 to his builds some time ago.
So I assume this is not a problem with newer MPlayer builds.

If you still experience problems when playing AV1 with a newer build, just open a new ticket.

Thanks and hoping all is working fine for you.
