4 months ago FFmpeg uses too much CPU, all it can have to the ceiling, even 90% of the total. I'm on a commercial build of AMD 64. It makes the PC freeze and crash. How can I limit the processing to 50% of the CPU?
I'm calling auto-editor like this:
@echo off set "input_file=%~1" "C:\Users\Username\AppData\Local\Programs\Python\Python312\Scripts\auto-editor.exe" --margin 1s,2sec --no-open "%input_file%" --my-ffmpeg %ffmpeg_threads% -c:v libx264 -b:v unset --extras "-preset slow -crf 22" pause
If you have a supported AMD or Nvidia GPU and a version of ffmpeg that supports GPU encoding you can just set the video codec to use the GPU encoder. For example I do this: auto-editor %1 --my-ffmpeg -c:v hevc_nvenc -m 5,30 this USED to work fine but now it throws an error that you cannot use that codec with mp4 files. I think this is a bug because like I said it used to work fine on mp4 files. I reported the issue, so in the meantime you can just tell it to output it as mkv, which works without that error. So it would look like this: auto-editor %1 --my-ffmpeg -c:v hevc_nvenc -m 5,30 -o outputfile.mkv
Now that is for a supported Nvidia GPU using a version of ffmpeg that supports GPU encoding. This way it will use hardly any of your CPU and offload the encoding to the GPU instead.
