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

<br><br>Is the Rtptime right? <br>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.
<br>Thank you.<br>sts<br><br><br>
