So can you explain why the video at link below (which is the one quoted in the original message) does not play in Linux Mint (where mplayer says it is the Debian version) ?
https://upload.disroot.org/r/35mvWXhS#O5Sud9anGqDShOOR972aWtzpBhC+efIslIszs870YxQ= Reminder: error message specifically lists video format (dav1d) as the problem... "Cannot find codec matching selected -vo and video format 0x31305641." (I've tried with all the possible video outputs listed by "-vo help". None works) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943062 Title: mplayer does not support AV1/dav1d (a.k.a. mplyer is bundled with an outdated ffmpeg) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mplayer/+bug/1943062/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
