Doug, A couple of my fixes have landed today, as well as ffmpeg 3.3 which fixes most of mpv's acceleration problems. However your comment reminds me there's another bug with mpv I need to open and fix... mpv will by default try to use the X11 display provided by Xwayland and ends up with vaapi-copy. You can work around that trivially and get hwdec=vaapi proper working again by hiding Xwayland:
env -uDISPLAY mpv --hwdec myvideo.mp4 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to intel-vaapi-driver in Ubuntu. https://bugs.launchpad.net/bugs/1698287 Title: VA-API fails to initialize in a Gnome Shell Wayland session To manage notifications about this bug go to: https://bugs.launchpad.net/libva/+bug/1698287/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
