• TypeError : 'function' object is not subscriptable Python with ffmpeg

  I am trying to make a clip concatenator, but the last subprocess call won’t run and gives me the error shown in the question.

  Problematic code :

  subprocess.call(['***', '-i', '"concat:' + clipString() + '"', '-c', 'copy', '-bsf:a aac_adtstoasc', 'output.mp4'])

  all places with * were paths such as :

• Use ffprobe to view audio tracks by language [on hold]

  19 novembre 2016, par crosenblum

  I wish to use ffprobe to list all audio streams, and show what language is used.

  Simply this is part of me trying to find ways to automatically remove non-english tracks from video files.

  I am new to ffprobe, but have had some experience using ffmpeg.

  Because I know that there is no guarantee of what order the language tracks may be.

  That is why I think it is vital to list each track, by number, then language, then when I know this part works, figure out how to remove the non-english ones.

  Thanks for your time.

• Mapping streams by language in FFmpeg

  6 décembre 2023, par ffmpeg123

  I have lots of files with multiple audio and subtitle languages, however the track numbers aren't consistent (the English audio stream isn't always the first) so using a command such as :

  


  ffmpeg -i "input.mkv" -map 0 -map -0:a:1 -c:v copy -c:a copy "output.mkv"


  


  doesn't yield expected results. After searching around I discovered it was possible to map streams based on language with this command :

  


  ffmpeg -i "input.mkv" -map 0 -map -0:m:language:eng -c:v copy -c:a copy "output.mkv"


  


  However -map -0:m:language:eng will remove all tracks with the English language flag. To keep the subtitle tracks you can use -map 0:s this is a good solution however, I want to know if it's possible to only map audio streams based on language. I.e.,

  


  I want to remove English audio while retaining all other streams without using stream IDs.
