# X must be running
vdpauinfo | grep HEVC # or
vdpauinfo --display :10 | grep HEVC
for 1060 GTX could return
HEVC_MAIN 153 262144 8192 8192
HEVC_MAIN_10 --- not supported ---
HEVC_MAIN_STILL --- not supported ---
HEVC_MAIN_12 --- not supported ---
HEVC_MAIN_444 --- not supported ---
which would mean no 10bit 4:2:2 HEVC I guess. edit: Or perhaps vdpau doesn’t support 10bit.
edit2: About mpv: On linux (nvidia) one would generally want nvdec-copy and with intel/amd vaapi-copy (JEEB).
