Mux an audio into an MP4?

[darkmaster006]

Hello there! So I have an mp4 file with five audio tracks, it also has one VobSub subtitle (that I don't wanna lose) and chapters. I want to add one more audio (with a 22065 delay) and not lose any of the other audios not the VobSub subs. I tried making an MKV but this inevitably makes me lose the VobSub subs for some reason; now, I thought, well, I should merge the audio into the mp4 and that's about it, but I haven't found a way to intuitively do this. I found something called MP4box, but it's terminal and I do not know how to add delay or how to add the audio. Any help is appreciated, thank you.

Thank you both, but that did not work (somehow, it muxed the same audio (the first one, inside the video), and erased all other tracks). Ultimately, after many tries, what ended up working was using My MP4Box GUI, demuxing all tracks (because it couldn't mux them from the mp4 itself!), and then muxing them all again with the new audio track I wanted to mux. Before that, I applied a 22065 delay to the new audio track with MeGUI, and, finally, we've got the files muxed, woo! Thanks for all the help, regardless. I'm not sure if it can be worked out with FFMPeg (can it mux VobSub?).

Use clever FFmpeg-GUI.
Load your mp4, click main, click multiplex, all source streams are already loaded, drag & drop the new audio file into the frame, insert 22065 in his delay field and click multiplex. Done.

I tried, but it said "sub format not supported" or something like that and couldn't mux the Vob Subs, am I doing something wrong?

dvd_subtitle in mp4 was blocked until now, but just tried it and it works.
Will provide a new beta today.

Thank you! I will try it out when it's done, then; thank you very much for the help.
