Solved hevc playback with hw decoding on nvidia using vdpau

Hello,

Has anyone been able to use hardware decoding with either mpv or mplayer for HEVC (h.265) videos on nvidia GTX 1070/1080 using vdpau?

Thank you.
 
mpv --gpu-context=x11 --gpu-hwdec-interop=vdpau-gl --hwdec=vdpau seems to produce the desired "Using hardware decoding (vdpau)." message. Although I'm not sure if it's actually worth it at twice the CPU load…
 
that did not work however.

mpv --msg-level=vd=debug --gpu-context=x11 --gpu-hwdec-interop=vdpau-gl --hwdec=vdpau --hwdec-image-format=yuv420p worked.

Using hardware decoding (vdpau).

thanks.
 
vdpauinfo to check whether it is supported ?
if you want to hardware decode, you need compile /usr/ports/graphics/mesadri driver by hand. and checked vdapu support option, I use vlc player with vdpau to get hardware decode. it works fine.

Thanks, but it's solved already as per above. I also marked the forum thread as "Solved".
