Comment (by Balling):

 >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.

 > The only conclusion I can come up with is that it doesn't matter what
 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
