Mpv does not play OPUS

Hi! I’ve been trying to play the highest quality youtube streaming (2k or 4k) with the highest audio quality too and most videos are not working on mpv, that returns many errors indicating that the format is not recognized(X11 or Wayland). I already compiled ffmpeg and downloaded youtube-dl. I even tried to manually compile mpv from the github source, but it did not work due to missing extensions…

Any suggestions?


@pawewav: Did you try the steps from : How-to: h264 etc. Support for Firefox (including ffmpeg install)
