Hi,
Could you tell me what you have been thinking about as a begin of solution?
Is the solution based on RTCP (for example Sending Report)?
Do you know when you will have a beta version? I can help you to test it maybe.
Will your solution work for VoIP application only or for streaming too?
For your information, I have also asked the same question to the gstreamer
mailing list, and I have been answered that I should place my 2 pipes in one
pipe.
I don't think this will enable to have a correct control of the 2 buffer
jitters.
Regards
Matthieu
