Combining an Audio-only and Video-only MP4 with ffmpeg on the command-line

Last night, I was downloading videos from Facebook, and found that they're sending their audio and video streams as separate, chunked responses.

I wanted to combine these, which fortunately is pretty trivial to do so using ffmpeg, thanks to a hint from this thread on SuperUser:

ffmpeg -i video.mp4 -i audio.mp4 -c copy out.mp4

See the thread above for other cases, such as when you want to reencode the audio, or replace the existing audio stream.
