   fftools/ffmpeg_sched: prevent demuxers from getting stuck
   When the furthest-behind stream is being fed by a demuxer that is also
   feeding packets to a choked filter graph, we need to unchoke that filter
   graph to prevent the demuxer from getting stuck trying to write packets to
   the choked filter graph.
   
   This situation can also apply recursively - if the demuxer is also writing
   to a filtergraph that is also reading from a choked demuxer, there is a
   similar deadlock.
   
   Solve all such deadlocks by just brute-force recursively unchoking all
   nodes that can somehow prevent this demuxer from writing packets. This
   should normally not result in any change in behavior, unless audio/video
   streams are badly desynchronized, in which case it may result in extra
   memory usage from the too-far-ahead stream buffering packets inside the
   muxer. (But this is, of course, preferable to a deadlock)
