no harware decode hevc whith 1060 - vdpau

Asked by lucmontagne

Hi,

I installed nvidia-367 last week. All was fine.
Yesterday I have some update, may be because of release 370 and now, mpv/vdpau doesn't want to use the hardware decoding for hevc.
I tried with ffmpeg (-hwaccel vdpau) : the same. Whith "nvidia-smi dmon -i 0", no doubt about that.

I tried with the new nvidia-370 but no result for HW decoding HEVC for videos n main profile.

The hardware encoding with ffmpeg and hevc_nven works fine. I can encode with hw but not decode !!

PS: Now, the problem is the same with 367.44 or 370.28.
It was fine from the first install of 367 (and my new card) until 1/2 days ago.
(meanwhile I reencode most of my videos in hevc... and my cheap CPU is not a big fan of sowftware decoding)
