This usually means that the application didn't tell gstrtpbin what the
clock-rate is for a source. You need to provide complete RTP caps on the
rtpbin or connect to the request-pt-map signal to provide this info to
gstrtpbin.

You probably also add a new sender source, which explains the warning
above.

That suggests a serious refcounting bug somewhere. runnning the
application with --gst-fatal-warnings and inside gdb can give a
backtrace that can give a hint what's going on.
