Hi list, I use VLC from nux-dextop as my default player. Recently began using youtube-dl and it grabs the video and audio just fine and produces .mkv files. I can play the resulting file just fine with Enqueue in SMPlayer, GXine, SMPlayer and Videos - VLC unfortunately says 'VLC could not decode the format "Opus"' Yet my google search indicates this issue was solved many releases ago - 2.0.4 and CentOS 7 is at version 2.2.2-4.el7 Anyone else have this problem and/or ideas on how to get it going? TIA Rob
