Help with Gstreamer and RTSP with Axis Camera

Hi Nicola,
I forgot to mention that I have the Axis camera set at 10kbps with the default resolution of 640 x 480 and a low frame rate of 1fps
with the sync=false setting, it sometimes takes a few seconds for movement from my hand to show up on the playback, and sometimes the motion is very fast when it does show my hand moving (much faster than I was moving it) any other ideas?
Thanks,
-Tom

Try "xvimagesink sync=false" should do the work,
