• How to preserve data stream with none codec from a video while compressing it using ffmpeg ?

  5 octobre 2022, par rj_7

  I'm using the following command to compress a video of size 1.5GB to 80 MB.

  


  ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:v -map 0:a -map 0:d output.mp4


  


  The problem I'm facing is - it doesn't copy the data stream to the output video even when I explicitly mention it via mapping. If I don't use the -map options for each kind of stream, it just process the video and audio as expected. But I also want the data stream in my output video.

  


  The logs for the above command are -

  I've also tried mapping the streams via number, that doesn't work either (shows same logs as above).

  


  ffmpeg -i input.mp4 -copy_unknown -map_metadata 0 -c copy -c:v h264 -b:v 5000k -c:a aac -b:a 48k -map 0:0 -map 0:1 -map 0:2 output.mp4


  


  So, essentially my question is - How to preserve data stream (packed) with none codec from a video while compressing it using ffmpeg ?

  When I use just
  ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
  It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
  What is wrong with the command ?
