I’m on Debian 9 (stretch) with a GeForce GTX 760 (NVE4/GK104/Kepler with VP5 decoding engine). I’m driving my card with Nouveau from Linux 4.11.0, and I’ve installed the proprietary firmware from version 325.15 of Nvidia’s driver, which Nouveau needs for acceleration.

Reproduction steps

mpv --hwdec=vdpau --vo=vdpau video.mkv

Expected behavior

My kernel log doesn’t show anything unusual – maybe some notifications about firmware being direct-loaded.

Actual behavior

Nouveau dumps hundreds of lines reading

nouveau 0000:00:0a.0: DRM: skipped size 0000000000000000

to my kernel log.

I believe this is a bug in mpv rather than in Mesa or Nouveau because playing the video with mplayer – mplayer -vc ffh264vdpau -vo vdpau video.mkv – prints no error messages.
