 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.

 Do not queque and thus request new frames when frames from other inputs
 are not available.

 Filter returns multiple frames from .fitler_frame. Libavfilter cache
 all such frames in memory.

 Do not cache frames in memory, forward them to next link immediately.
