<div dir="ltr">Obviously there is a caps negotiation problem. Try adding omx_h264enc:4 to your gst_debug setting to try to see what caps it is expecting. Just for grins you might try changing your capture format, though I can't suggest why the pipeline elements would behave differently in the rtsp rtpbin than outside. But try it to see what happens. </div><div class="gmail_extra"> <div class="gmail_quote">On Wed, Jul 3, 2013 at 8:11 PM, jlancaster <<a href="mailto:jeff_lancaster@msn.com" target="_blank">jeff_lancaster@msn.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I am using the gst-rtsp-server 10.8 to serve video from v4l2src.
