> well, does your GPU support it in the first place?
The h264_vaapi.mp4 profile works for me without any problem. I tried
adding "cin_hw_dev=vaapi" to the profile and now the error is:
[av1_vaapi @ 0x7f926c088e00] No usable encoding profile found.
FFMPEG::open_encoder err: Function not implemented
guess setting cin-specific parameter like this upsets libavcodec ....
I have an AMD RT5700XT and it should support vaapi well.
well, av1 is new hw feature ...
this site lists its architecture as rdna, and av1 support started from rdna2 ?
ah, pc arms race when 4 years old card already feels old .....
