Please read Tim answer to that, rtspsrc has a latency property (in ms).
By default it's configured to 2 seconds (2000) which is added to the
server latency and network latency. Many other element can be configured
like this. Setting sync=false will also break libsync btw. So for rtsp
is not desired.
