<div>Hi, gstreamer-devel:</div> <div> </div> <div>    1. Add a probe in front of your sink element and print every buffer's timestamp. If the timestamp is discontinuous, consider all the elements in your pipeline which modified the timestamp.</div> <div> </div> <div>    2. If the timestamp of buffer is OK, watch the CPU load. It is possible that your processor cannot decode quickly.</div> <div> </div> <div>Eric Zhang<br></div> <div class="gmail_quote">2008/12/16 Wierd O <span dir="ltr"><<a href="mailto:wierdo_b@hotmail.com">wierdo_b@hotmail.com</a>></span><br> <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> <div><br>Hi all ,<br><br>I am using gstreamer to stream video from a file source in iMX27 freescale app processor.
