Two RTP Ports or wav files over RTSP with 2 channels of RTP

Hello everyone,

I'm trying to build a pipeline that would be able to get 2 udp sources or 2
wav files, and afterwards stream them both using RTSP as the signaling part
and for the media part using a single RTP.
I wish to do that the RTP would have 2 channels for each source.

I used the *interleave* module to take 2 wav files and save them to a mixed
wav file.
Afterward, I tried to take a working pipeline of mine which take that wav
file(mixed with 2 channels - stereo) and stream it using RTSP, and the
result was RTP with only 1 SSRC(Only 1 channel).

Plus, I also tried to make a pipeline that takes a udpsrc and does
conversions on them so the result of the RTP would go to a wav file.
In this case, I have to deal with 2 udp sources that I not necesarily know
their codec or other configurations like clock-rate or voice bit channels
amount.

I'm pretty new to GStreamer pipeline, so I feel a little bit confused
regarding building this pipeline efficiently so I'm maybe doing something
foolish and I don't see it :) 

Sincerely yours and thanks!
