This test is intended to check the RTP source / sink operability.
To do this, two processing queues are being allocated:
"generator": source/random -> sink/rtp
"checker": source/rtp -> sink/checker
The first one generates some amount of random bytes (payload),
and stores them inside a buffer that is shared between both
queues.
After generation, a payload is being sent from the first
queue via an RTP sink, and then being received by the second
via an RTP source.
As both queues do use a shared buffer, the last item of the
second queue (named 'sink/checker') is able to compare a
received payload with expected.
