Problem:
Filter takes 3 streams, returns 1 stream.
If first input generates frames faster than 2 and/or 3 it will
pointlessly start to queue frames from 1st input.
Solution:
Do not queque and thus request new frames when frames from other inputs
are not available.
Problem:
Filter returns multiple frames from .fitler_frame. Libavfilter cache
all such frames in memory.
Solution:
Do not cache frames in memory, forward them to next link immediately.
