By default, rtspsrc (as used by playbin) has a latency of 2 seconds.
You can configure this to a lower value with the "latency" property on
the source. The best value to choose depends on your network.


If you're using playbin, you can use the source-setup signal to get
access to the source right after it was created. You would then be able
to change the latency property there.


Also you mentioned using "playbin2". Please use GStreamer 1.x, the 0.10
release series is no longer maintained since more than 3 years now. You
can find 1.6.0 binaries for iOS here:
