font-family:Arial'>I’m just getting started with app_rtsp/app_transcoder
and I’m getting a lot of messages about overflow/underflow. For the
most part the video stream looks ok without much packet loss. The source
stream is mp4v 320x240 8 fps, 128 kbps, I’m transcoding it to cif which
is higher that what the example had used. Also if anybody knows what the
gs=50 part means. And the example for app_transcode I believe should use
pipes instead of commas?<o:p></o:p></span></font></p>
