Adding Audio To A Video File

I'm trying to add a wav file as background to an mp4 video and have no idea where to start...I've tried looking in to the 'Video Editor' API but found nothing useful... Is it worth

Solution 1:

Yes ffmpeg is good enough

ffmpeg -i in.mp4 -i in.wav -acodec <give your codec> -vcodec copy out.mp4

should do the trick and works for me.
