>On windows I used the following command, changing cuda with the other
options written above
You are supposed to use -f null NUL instead of -f null - on windows. -
(pipe) is not fast on Windows, I believe.

hwaccel you use.
No true, I think nvdec (-hwaccel cuda) takes less energy and less memory
than -c:v hevc_cuvid -i mandelbrot-yuv420p-2160p.mov
you can see that in nvidia-smi
