Niklas Haas 5f4cbb5617 fftools/ffmpeg_sched: choke inputs during filtergraph configuration ...

Currently, while the filter graph is being initially created, the scheduler
continues demuxing frames on the last input that happened to be active before
the filter graph was complete.

This can lead to an excess number of decoded frames "piling" up on this input,
regardless of whether or not it will actually be requested by the configured
filter graph. Suspending the filter graph during this initialization phase
reduces the amount of wasted memory.
