Description
This is a follow-up to #1331 which directly addresses the root cause of that problem.
It seems ExoPlayer can't play mkv which have their tracks in the end cluster verses the start cluster. While less common, it is still mkv spec compliant. Exoplayer opens and the seek bar seems to advance at a normal rate, but the screen is black and no video or audio plays.
This mkv plays fine in mpv and ffmpeg transcoding within Wholphin and vlc on my Android TV box

If this is discovered to be a problem with ExoPlayer itself and not the Jellyfin app, I will happily open a ticket upstream in ExoPlayer.
