Hello dear WAMUGgers

For interest, based on recent posts:

Muxed files are those with a combined video and audio track. De- muxing is the act of separating this video and audio into separate tracks. Probably 'un-demuxing' them would be putting them back together again. ie muxing them.

Mux, using Apple dictionary, is short for multiplex:
1 a system or signal involving simultaneous transmission of several messages along a single channel of communication. Compare with duplex , simplex .
2 a movie theater with several separate screens.

So if you want to un-demux a muxed file, perhaps you're going to mux it? Muxmux indeed!

That is an 'oxymoron', a word I had trouble with as a young boy being taught by particularly pedantic well-educated Jesuit priests, fluent in Latin and Greek. I knew that a moron was a fool, so how could we have a 'sharp fool'? A particularly intelligent fool, or a stupid intellectual one?
40 years later, I'm still confused.
