1871	how to batch extract all ac3 streams from vob file?	abducted		"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?
