  9 avril 2016, par AlbanMar31

  How to join two video files without losing any channel with ffmpeg ?

  Origin, we have 2 video files ts record with the TV decoder TNT.

  Destination we would have one single video file containing the same number of channels as each original file.

  Goal : The resulting video will have the same number of channels that each of the original videos.

  usual command to merge :

  ffmpeg -threads 4 -i data0001.ts -i data0002.ts -i data0003.ts -c copy -scodec copy video.ts
  

  Channel information video files :

  $ ffprobe data0001.ts -hide_banner
  

  give me this type of result :

  Stream #0:0 : Video: mpeg2video ...
  Stream #0:1: Audio: mp2 ...  
  Stream #0:2: Audio: mp2 
  Stream #0:3: Subtitle: dvb_subtitle 
  Stream #0:4: Subtitle: dvb_subtitle
  

• ffmpeg - is there a way to -map 0:m:language:eng if it exists, otherwise use the default ?

  9 avril 2016, par momo

  If a source has 'eng' as an audio track, use that, otherwise use the default or audio track zero?

  Is this possible?

  I have tried:

   -map 0:m:language:eng? -map 0:a:0?
  

  But that ends up always using the default one.
