ffmpeg - How to change threads/pools(x265) on the fly?












-1















ffmpeg -i filename.mkv -vcodec libx265 -preset medium -x265-params crf=23:pools=4 hevc.mkv



Is there a way to send a signal to the ffmpeg process to force it to change number of threads(pools)?



Context:
I want ffmpeg to encode with 4 threads while system idles and switch to 2 when there's activity. Now I instead have to just kill -STOP/-CONT



Solution:
Have 2 ffmpeg instances(different files) run at the same time. One with 4 threads make convert during idling, other with 2 threads convert when there is activity.

  • You can’t change the number of threads. You can change thread priority using nice/renice. Unless you’re using windows. Then IDK.
