how to do this with our mistake. Please help me

Answer 1

In recent versions, this

ffmpeg -stream_loop 4 -i input.mp4 -c copy output.mp4

Due to an error, the above does not work with MP4. But if you wrap MKV, this works for me.

ffmpeg -i input.mp4 -c copy output.mkv

then

ffmpeg -stream_loop 4 -i output.mkv -c copy output.mp4
