Ah, so that it's still a legal stream that canb be played, but plays
I'm not aware of any standardized method to do this, nor of any way to
achieve this with ffmpeg. The "geq" filter can apply a function to
pixels (as some other filter probably can with audio), but you would
need a way to pass it an encryption scheme. I don't think something like
this is implemented or even in consideration - but I might be wrong.
