  FFMPEG – Copy empty streams

  Posted by Grant Mcnair on November 6, 2019 at 9:53 pm

  Does anyone know of a way to force ffmpeg to copy empty video streams? I have a video file from a ProRes recorder (Odyssey 7Q+) that has a corrupted vidoe (stream 0). When I replace the stream and copy it a new file, it produces a playable file with streams in the correct order, but in the original there are blank streams that the proprietary muxing software I am using needs to see in order to work. But these empty streams don’t copy over to the new file. The original has 11 streams, the new file had 7. In the original file there are 4 empty streams.

  I am using this code:
  ffmpeg -i Video1.mov -i Video2.mov -map 1:0 -map 0:1 -map 0:2 -map 0:3 -map 0:4 -map 0:5 -map 0:6 -map 0:7 -map 0:8 -map 0:9 -map 0:10 -timecode 24:10:43;18 -c copy New_Video.mov
