Thibault Saunier 871fa29639 streamsplitter/combiner: Drain encoder before switching branch
Otherwise we miht have frames queued in the encoder from the old branch
that do not get encoded/muxed when they should.

The implementation is a bit 'weird' but the rational and solution
is documented in the code.
