• How to split video into parts audio/video/text in one command ?

  22 novembre 2020, par lockwise

  I have one video file .mkv.
Inside this file, there is a video track, 3 audio tracks, 2 subtitles, a poster file, and a backdrop file.
Does ffmpeg know how to split .mkv into separate parts, video / 3 audio / 2 subtitles ?

  


  ~# ffmpeg -hide_banner -i input.mkv

  I need :

  


  

  • Video

    

    • input0.mp4

    


    


  


  • Audio

    

    • input0.m4a

    


    • input1.m4a

    


    • input2.m4a

    


    


  


  • Subtitle

    

    • input0.vtt

    


    • input1.vtt

    


    


  


  


  These commands do the splitting, but I need to know exactly how many audio files and how many subtitle files are in the mkv.

  


  ffmpeg -y -i input.mkv \
  -map 0:v:0 -c:v libx264 output0.mp4


  


  ffmpeg -y -i input.mkv \
  -map 0:a:0 -c:a aac output0.m4a \
  -map 0:a:1 -c:a aac output1.m4a \
  -map 0:a:2 -c:a aac output2.m4a


  


  ffmpeg -y -i input.mkv \
  -map 0:s:0 output0.vtt \
  -map 0:s:1 output1.vtt


  


  Is it possible to make such divisions without knowing the file number 0:a:2, 0:s:1 ?

  There is the part of my music bot in Discord, I don't really know why it doesn't work. Actually, I tried to use someone's old code, so it needs to be fixed. I have cut out the most important parts of the code, which most likely had an error.
I found other questions, but there was another errors.
After trying to start the video, I get the following errors :
[out#0/s16le @ 000002452f906a00] Output file does not contain any stream
Error opening output file pipe:1.
Error opening output files : Invalid argument
