You need to add an rtpjitterbuffer element between udpsrc and
rtph264depay to make sure clock drift between sender and receiver get
handled correctly. You can adjust the latency via the rtpjitterbuffer's
latency property (it will handle the drift also with low latency of
course, what latency is suitable mostly depends on your transport).
