Ah, yes, this is an option, but again, not something I expect to be able
to do before 3.0.

The decoder is indeed ahead of realtime, when audio is stopped, this can
be solved in a fairly trivial way, when audio is playing, I'm not sure
how much will be doable before 3.0, but I believe Jens also has some
