• stream_loop generate a big size video [FFMPEG]

  26 mars 2021, par Mouaad Abdelghafour AITALI

  I'm trying to loop a short video for e.g. 190 time to match the audio length, I use the following code :

  


  -y -stream_loop  190  -i input.mp4 -c copy output.mp4


  


  The command above works, but it generates video with huge size for video with 3min the size is 885 MB

  Or there's any way I can loop the video to match the audio length without using -stream_loop
