If you need this you might as well be replacing LiveCode's multimedia support.

mergAV is part of the way there but that's just iOS and OS X. If there's an Android equivalent of AVFoundation I'd love to hear about it as I thought ffmpeg was used there for that type of stuff. The video composition stuff in AVFoundation blew me away with its performance on mobile.
