In a nutshell, you need to listen for the "on-ssrc-active" signal from
the rtpbin and query the "stats" property from the rtpsource connected
to the stream.

To retrieve the structure you need to:

1) Retrieve the rtpsession bound to your stream: it's in the
"internal-session" property of the GstRTPSession you'll get as an
argument in the signal handler.

2) Get the rtpsource element from the "internal-source"
property of the rtpsession.

3) Get the session stats structure through the "stats" property of the
rtpsource.

Then you need to process the fields you're interested into (they are
"rb-jitter" and "rb-packetslost").
