MPEG-TS to MP4

[Edward Hervey]

Hi,

  You're missing queue elements a bit everywhere. Essentially:

* Before N-to-1 elements (muxers) : put a queue on each incoming stream.
  Ex : demux ! queue ! ...

* After 1-to-N elements (demuxers) : put a queue on each outgoing stream
  Ex: ... ! queue ! mux

* Before sink : put a queue before the sinks (unless you already have one just
before)

  Withtout that ... you're trying to run everything in one thread ... and that
will deadlock.

  BR,

    Edward
