AW: AW: Impossible to play a rtsp stream

Tue Jul 17 04:41:30 PDT 2012

Hello Marc

You are right. After some testing today, I get another problem with another
rtsp stream (network video camera). After starting with:

gst-launch-0.10 -v uridecodebin uri=rtsp://172.16.22.20:554 !
fastoverlaysink sync=false

the stream is displayed very well. After some time the picture hangs. Then I
have to quit gstreamer with Strg + C.
The point when the picture hangs up is constantly after "FB display frame
count = 129".

Also I get very much output from gstreamer. What kind of information is
hidden in this output?

Are there any other tests I can do, to see where the problem is?

Also I tried to switch to a newer gstreamer version. But it looks like the
Marvell specific codec plugins does not work with the newer version...

I think both suggestions are pointing the same root cause; as long as you
take into account that using sync=0 does not solve your problem, it merely
hides it.
