--- Comment #9 from joeri.exelmans@gmail.com --- Interesting, probably a bug in the r600 gallium driver then. Mpv with --hwdec=vdpau-copy (instead of --hwdec=vdpau) seems to work for me as well. Maybe VLC also uses that method.
So far I've built Mesa git versions

and they all work with Kodi and VDPAU.
The blue screen in mpv could be a bug in mpv 0.25 or Mesa still. My guess is mpv because never had that problem with mpv 0.14 from Ubuntu repository.
