UdpSrc: streaming stopped, reason not-negotiated (-4)

Hello gstreamer developers,


I have a problem with the UdpSrc. My application is supposed to process
live audio(i.e. PCMU) and dtmf(TELEPHONE-EVENT). Both are rtp messages sent
to the same port.

With debug enabled the UdpSrc posts a warning: streaming stopped, reason
not-negotiated (-4).

I have my pipeline converted from dot to pdf and attached to this mail.

Is it even possible to use the UdpSrc this way, having caps of pcmu and
telephone event?
Is my general concept to process audio/dtmf correct?

Any ideas are appreciated.


Regards Jochen Jung
