hi - encoding really slow

[Selur]

Simply checking whether any of the calls I posted for testing doesn't report an error, would help.

[AVHWFramesContext @ 0000026f7eef0440] Pixel format 'yuv420p10le' is not supported
[hevc @ 0000026f7ec4adc0] Error initializing a CUDA frame pool
cuvid hwaccel requested for input stream #0:0, but cannot be initialized.

sounds like the decoding doesn't work using CUVID and outputting '-pix_fmt yuv420p10le'.
Does it change when using '-pix_fmt yuv420p'?
