I do not agree there. If it is possible to add and remove ES's dynamically, it
should be possible to remove all of them, then add new ones. This is neither
sufficient nor necessary a condition to drain the muxer.
Muxers should "drain" up to the PCR, regardless of any ES or even the whole
stream ending. Of course, that requires passing the PCR (or its translation)
to the stream outputs and muxers.
