Comment (by Danixu):
With your command the program uses less CPU time, but continues using more
than one thread (about 70%-85%). With threads 2 or 8 uses the same CPU.
I've tried with MP4 instead hevc to use libx264, and works fine (just 50%
and with threads 2 about 95%).
Finally, the x264 problem is command line, because this works:
{{{
% ffmpeg.exe -i in.mp4 -threads 1 -c:v libx264 out.mp4
}}}
but with x265 still no working.
