<div> Hi , </div> <div> </div> <div> </div> <div> You are setting caps 800x600 in caps but you output shows 1280x720 ?? </div> <div><br> And why you are waiting to receive a complete frame ? you can simply push the data to appsrc , h264parse is there to build a complete frame .</div> <div> </div> <div><br> </div> <div class="gmail_quote">On Thu, Jul 15, 2010 at 11:15 AM, Prabhulinga Swamy B S <span dir="ltr"><<a href="http://prabhulingaswamy.bs">prabhulingaswamy.bs</a>@<a href="http://globaledgesoft.com">globaledgesoft.com</a>></span> wrote:<br> <blockquote style="BORDER-LEFT: #ccc 1px solid; MARGIN: 0px 0px 0px 0.8ex; PADDING-LEFT: 1ex" class="gmail_quote">hi Sandeep,<br> thank you for your reply.<br><br> Yes, I'm sure of receiving 30 fps from the network.
