Apologies if this is the incorrect section to post this.
I need to take mp4 files with multiple audio tracks and extract them to individual mp4 files.
Using MP4Box, I can run this command:
mp4box.exe -raw * "Input.mp4"
And that will 'demux' the file into raw streams, so if the source had 1 video track and 8 audio tracks, I would end up with 9 files - 1 *.264 and 8 *.aac files.
If I needed these raw streams each encapsulated in an mp4 wrapper, how would I do this?
It looks like this:
mp4box -single [TrackID] "Input.mp4"
works when the TrackID is specified, but I need something like this:
mp4box -single * "Input.mp4"
Which currently reports a bad parameter.
Any ideas?
Thanks
