Are you on an ancient xserver-xorg-video-nouveau by any chance? Anything from
2012 or later should be good enough, it's commit d575a28a502 that tells it to
load libvdpau_nouveau.so instead of nvidia. You might need to update libvdpau too.
The vuc files are probably ok, but it's not going to work without the kernel firmware files.
The ones I'm getting are:
vuc-h264-0 vuc-mpeg12-0 vuc-mpeg4-0 vuc-mpeg4-1 vuc-vc1-0 vuc-vc1-1 vuc-vc1-2
This is enough for all codecs, but it will just fail later on without userspace codecs. It should
attempt to create the kernel stuff first, which it doesn't from what I can tell from your logs.
