Which demuxer is this? Are you transferring MPEG-TS over RTP? Also
which transcoding elements are used? Does the same happen if you only
output the audio/video directly to a sink without transcoding and also
without sending over the network again?

The clock-slaving algorithm implemented in rtpbin (rtpjitterbuffer to
be exact) should prevent such problems if caused by clock drift between
the sender and receiver clock.
