[Live-devel] Vbrick

[S ts]

Hi,
I am trying to use openRTSP to record a video stream from vbrick in fedora
linux.
For a quicktime stream I use the command:
openRTSP -q -f 30 -h 240 -w 320 -V  rtsp://vbrick>tst.mov

The output is:

Is the Rtptime right?
In Quicktime this video shows a black screen but you can hear the audio. In
VLC both audio and video are present but are out of synch. I am new to RTSP
so would appreciate any help anyone can give me in trying to solve this
problem.
Thank you.
