As I've mentioned before, there's no concept of flushing in a sout 
chain. Only individual defined flush control is possible: Decoders, 
packetizers. A generic flush has no meaning. What do I do when it hits, 
for example, muxers ?

Trying to solve an asynchronous random access discontinuity handling 
issue with a synchronous command can't work without breaking the concept 
of stream.
