This seems phenomenally uninteresting and trivial; running multiple
encodes at the same time isn't multithreading, it's multiple
processes.  Even if you theoretically force them inside the same
process, you're still running multiple independent tasks.

What would be interesting is multithreading *individual* encoding and
decoding tasks.
