[HELP] FFmpeg x264 not fully utilizing the CPU
#2
Why not simply use a mkv with a cover instead of the video stream?
Why the 6 fps, i mean when using just one image the fps should matter?
Why are you using crf ?
Why the '-scrict -2' ?
Also your encoding will probably be (a lot) faster if you specify the '-r 6' before the "-i image".
How fast is:
ffmpeg -y -loop 1 -r 6 -i <path to image> -i <path to audio> -c:v libx264 -q:v 23 -preset ultrafast -c:a copy -shortest <path to output>
for you?
(Also if you have an nvida cpu or intel cpu with a graphic processor you might want to use nvenc or qsvenc instead of x264)

Cu Selur

Ps.: your goal shouldn't be a higher cpu utilization, but higher speed. Since you basically tell the encoder to do nothing it's to be expected that the cpu utilization isn't high.

Dev versions are in the 'experimental'-folder of my GoogleDrive, which is linked on the download page.
