I tried the latency property and it made sense. I had another problem before: With sync=true on the video element, I had long dropouts. This was due to the network controller which is not able to work at full GBit speed (max speed is about 400 Mbit/s). With sync=true each lost RTP packet resulted in a dropout of about 2 seconds. With sync=false, lost RTP packets simply gave a short hickup in the video but nothing problematic as with sync=true. I got the impression that the clock sync got irritated and needed to resync after a lost rtp packet. The issue is important as, like I said, there is even a "sync=false" patch in Qt5.3.1 now. If this is not the way to go we should report the right way to fix the problem here: <a class="moz-txt-link-freetext" href="https://bugreports.qt-project.org/browse/QTBUG-38465">https://bugreports.qt-project.org/browse/QTBUG-38465</a> Michael P.S.: Could anybody of you guys comment on the typefind problem I have in playbin (see other post)? That would be very hepful. Thanks a lot.

How to reduce "configured latency"? There is even a patch in Qt5.3.1 which adds "sync=false" to live media. So, if this is not a good idea, what is the alternative? (As I said, in my experiments sync=true gave latency of 3-5 seconds and a very problematic behaviour if some RTP packets have been lost, resulting in large dropout of several seconds. So far, sync=false runs perfectly for me, reducing latency to less than 1 second and making the system much more immune againt lost RTP packets.) </blockquote> 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.
