           Summary: RTSP connection to IP camera failed

            Status: UNCONFIRMED

In older GStreamer version (0.10) I can do the following and it works very
well:
  gst-launch-0.10 playbin2 uri=rtsp://192.168.0.27/VideoInput/1/h264/1
If I do the same with current version (1.4.1) it failes very often:
  gst-launch-1.0 playbin uri=rtsp://192.168.0.27/VideoInput/1/h264/1
With 0.10 version it works very reliable. With 1.0 version it's very unreliable
and only works sometimes.

The device which I used here is a video encoder from Siqura. But I got the same
problems with IP cameras from Sony and Siemens. They also worked very well in
0.10 version but not in 1.0. If it would help I could supply Wireshark capture
files.
