This command will (if I understand correctly) transcode your audio. Using
"-c:a copy" will copy the audio.mp3 into the muxed.mp4 container. Same
thing with "-c:v copy" as the video.mp4 is (obviously) already in an MP4
container, it should be a trivial matter to mux the two streams into a
single MP4.

It would help us even more if you could provide what your console outputs
when the command runs.
