    7 septembre 2023, par jpvans

    Trying to get the best quality/performance when putting four sources together with ffmpeg.

    


    My current ffmpeg command is :

    


    ffmpeg -input_format h264 -s 1920x1080 -i /dev/video0  -input_format h264 -s 1920x1080 -i /dev/video1 -input_format h264 -s 1920x1080 -i /dev/video2  -input_format h264 -s 1920x1080 -i /dev/video3 -filter_complex \

    ffmpeg reports only 15 fps when the sources provide 30fps wondering what can be done to improve that
