non 4:2:0 encoding fails on iHD with ICL #29

Closed bmegli closed 3 years ago

bmegli commented 3 years ago

e.g. for rgb0 or bgr0 format

In logs visible error message:

[AVHWFramesContext @ 0x55b7ec4c57c0] Failed to write image to surface 0x13: -1 (unknown libva error).

Some color conversions with iHD require full driver (not only free).

The fix is to install full driver 

sudo apt install intel-media-va-driver-non-free
