Good! ... now, how to use it? What are the parameters?
I'm more used to libmpcodecs-style parameters passing, so I can't see what are the expected parameters, nor do I see what type and range they accept.

I'm _guessing_ the expected parameters are:

but I don't know what unit they may all be.

Could you help me document this Michael?
