Trying to play h264 encoded video with mpv --vo=opengl --hwdec=vdpau results in

I tested mesa (git-227b1af866) patched with "radeon/vcn: fix mpeg4 msg buffer
settings" by Boyuan Zang, but that didn't fix my problem. I also tested
today's pull request for linux drm-fixes-4.17, but the issue is still present.
