How to access multiple audio tracks?
« on: September 10, 2019, 01:10:09 PM »
Hi,

A friend sent me a video with around 40 audio tracks, which he would like me to separate out the relevant tracks. However, the dropdown list in the audio track select screen only lists tracks 0 to 6. Is there a way to get to the other tracks?

Thanks.

You don't specify which type of media file these 40 audio tracks are muxed into. If it is a MP4, you would need to bump the value of _3GP_MAX_TRACKS and rebuild Avidemux from source. No idea how it will cope with more than 9 tracks (the max number of tracks I ever tried).

If you cannot build Avidemux from source, try ffmpeg.

Yes, it's an MP4. I'll try what you suggested, thanks.
