Yep, I know about this. Needs yet another change... just need to figure out how to best resolve it. > > $ VDPAU_DRIVER=nouveau mpv --hwdec=vdpau -vo=opengl /path/to/MP4 > Driver 'opengl' has been replaced with 'gpu'! > Playing: /path/to/MP4 > (+) Video --vid=1 (*) (h264 1280x720 23.976fps) > (+) Audio --aid=1 --alang=eng (*) (aac 2ch 44100Hz) > Cannot load libcuda.so.1 > Using hardware decoding (vdpau). > VO: [gpu] 1280x720 vdpau[yuv420p] > AO: [pulse] 44100Hz stereo 2ch float > AV: 00:00:12 / 00:02:03 (10%) A-V: 0.000 mpv doesn't seem to work, yeah. FWIW I'd expect -vo vdpau to work (not -vo opengl, which is unlikely to work with vdpau decoding). But it doesn't, I get some kind of error (something is trying to submit a batch with an unregistered bo or something). mplayer works fine though. See https://nouveau.freedesktop.org/wiki/VideoAcceleration/ for instructions on how to use it.
