The VideoLAN Forums

Hello,
I have a video file which contains a few audio channels. Each channel for other language.

Is there an option to remove the unnecessary channels? If so, How? I didn't menage to find an explanation in Google.
I'm afraid that these channels, Which i don't use, Makes the file larger and occupying more space on the hard drive.

you need to specify each track you want to keep (named as channel in UI)
--audio-track=1,2

Otherwise, if tracks have an id property
--audio-track-id=

Can you explain exactly how?

I didn't menage to find what i need.

Anyone can send an exact link or explain here how to remove an audio channel?
