Short answer: yes.

See the example applications here:

Instead of sharing a network clock, you could also share a GStreamer
NTP or PTP clock, or alternatively set the system clock with wall clock
time on the pipelines and synchronize the system clocks outside

These examples are doing RTSP, but only to make the setup of the rtpbin
simpler. What matters is those properties that are set on rtpbin and
proper selection of the pipeline clock.
