Add an audio track to a video

[Артем]

Hi, is it possible to add an audio track to an mp4 file (in which there is no sound) using your project?

There is nothing prepared for doing this, so you need to write quite a lot of code yourself.

If you want a Swiss army knife that can do something like adding tracks, I'd recommend MP4Box. Something like

MP4Box -add audio.mp4 -add infile.mp4 outfile.mp4

should hopefully work.

Isn't this example what I need?
