Hi,<br>thank you for your reply. <br>I am using kill -hup command to end the program. Tried the -y option and the sync issue gets worse. <br>The stream when played in quick time is 352*240 at 30fps. so I changed the commend to the new dimensions but the problem is still there.
<br>Could there be a problem with the sdp?<br>below is the sdp created by vbrick:<br>v=0<br>o=- 5699360993 1 IN IP4 <a href="http://192.168.96.151">192.168.96.151</a><br>s=MAC0007df008ef9 Program 1<br>i=VBrick Streaming Video
