from what I understand, what you need is already there: see the
"use-pipeline-clock" and "ntp-sync" properties of GstRtpBin. They will
enable you to properly synchronize the streams bw sender and receiver.
In order to use you own clock for the sending pipeline, even though
I've never tried it before it should be fairly easy to implement
GstClock and pass an instance of that class to the pipeline through
gst_pipeline_use_clock.
