  • ffmpeg x264 encoding cpu usage

    4 décembre 2016, par Amin Fazlali

    I want to convert a mkv formatted video to mp4, using the ffmpeg application.
    and for that I ran below command in terminal :

    ffmpeg -y -i c38a4990774b3c23.mkv -c:v libx264 -c:a aac -r 25 -strict -2 -map_metadata -1 -movflags faststart -vf "crop=1920:800:0:4, scale=iw*min(426/iw\,240/ih):ih*min(426/iw\,240/ih), pad=426:240:(426-iw*min(426/iw\,240/ih))/2:(240-ih*min(426/iw\,240/ih))/2, setsar=sar=1" output.mp4

    I have compiled ffmpeg with —enable-pthread configuration

    when I run this command on my personal PC with a 3.2GHz quad core cpu, it uses 60% of overall cpu process and encode video with 150fps ; but when I run this command on a production server with 8 2.4GHz dual core cpu (16 core) it only uses up to 20% of overall cpu process and encode video with 97fps.

    I have also tried ramdisk but I got no performance improvement.
