It uses vtdec, which is not perfect and not really controllable about
latency. (Also don't set a latency of 0 on rtpsrc/rtpjitterbufer!)

Your pipeline is also configured with a latency of 0, so in theory
there shouldn't be any latency and nothing should work at all as 0 is
clearly wrong for anything going over the network.
