I think the idea of a threadpool is a good idea - we have usecases
where we want to make a videowall of HD material with like 30 HD
sources that need to all be deinterlaced then scaled etc.

But it shouldn't be a global threadpool - it should be a generic
threadpool that could even be used by non-FFmpeg tasks. Presumably you
would attach it to a decoder and the decoder would use it (very
handwavy I know).
