<DIV><FONT size=2></FONT>
<DIV class=RTE><FONT size=2>Sorry for the delay. Here is my thoughts on this:</FONT></DIV>
<DIV class=RTE><FONT size=2>1) After you start RTSP. you open audio and video RTP channels.</FONT></DIV>
<DIV class=RTE><FONT size=2>2) You start your audio and video encoding engine.</FONT></DIV>
<DIV class=RTE><FONT size=2>3) After you get first video frame then start to send video and audio frames. This way you will have prefect a/v sync. </FONT></DIV>
<DIV class=RTE><FONT size=2>4) The video channel time stamp is calc use 90000Hz scale. And audio is use 8000 Hz.</FONT></DIV>
<DIV class=RTE><FONT size=2>5) Also you need make sure to use system time to determine the timestamp not use video frame time or audio frame time in case of lose frames.</FONT></DIV>
<DIV class=RTE> </DIV>
<DIV class=RTE><FONT size=2>Hope that help!</FONT></DIV>
