 hi !
 I have vob files with multiple audio inside.
 I would like to extract all the audio streams from all the vob files
 automatically.

 I have tried this :

 for %%a in ("*.vob") do ffmpeg -i %%a -vn -acodec copy %%~na.ac3

 but this will extract only one ac3 track from the vobs, not all of them.
 So how to batch extract all ac3 streams from the vob files please?
