  aacdec_usac : remove fallback for custom maps with invalid position
  Not needed as every possible index is mapped.

• ffmpeg when asked to map a .mov file's streams 0,1,3 actually maps streams 0,1,2

  15 septembre 2023, par user2258729

  I'm trying the following :

  


  Start with in.mov which has 4 streams 0:0 - 0:3.

  


  Audio, Video, Data (unknown), and mJpeg.

  


  Trying to map 0:0, 0:1, and 0:3 into out013.mov.

  


  ffmpeg -i in.mov -map 0 -map -0:2 -c copy out013.mov

  


  or

  


  ffmpeg -i in.mov -map 0:0 -map 0:1 -map 0:2 -c copy out013.mov

  


  ffmpeg tells me that 3 streams are mapped :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:3 -> #0:2 (copy)


  


  ffprobe disagrees. According to it what really happened was :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:2 -> #0:2 (copy)


  


  "Who needs a thumbnail image anyways, screw it !" I said. "Let's just get rid of the data."

  


  ffmpeg -i out013.mov -map 0:0 -map 0:1 -c copy out01.mov

  


  ffmpeg tells me that 2 streams are mapped :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)


  


  ffprobe disagrees. According to it what really happened was :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:2 -> #0:2 (copy)


  


  Seems like I can't rid myself of that data stream (0:2).

  


  Below is the output from the ffprobe and ffmpeg for the first scenario.

  


  Any ideas ?
