Hi,sudarshan bisht, Marco Ballesio,<br>
Thanks for your reply.<br>
Follow sudarshan bisht's advice, I have add the h264parse plugin between<br>
h264depay and decodebin.<br>
Follow Marco Ballesio's advice ,I have delete the udpsink's property<br>
sync=false, and delete the redundant caps:ssrc clock-base and sequm-base.<br>
As do above, the same error is still exist.<br>
<div class="im"><br>
server:<br>
gst-launch-0.10 -v videotestsrc ! x264enc ! rtph264pay ! udpsink<br>
host=127.0.0.1 port=40000<br>
<br>
</div><div class="im">client:<br>
gst-launch-0.10 -v udpsrc<br>
caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96"<br>
</div>port=40000 ! rtph264depay ! h264parse ! decodebin ! xvimagesink<br></blockquote><div><br>this is better:<br><br>gst-launch-0.10 -v udpsrc port=40000 ! "application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264,payload=(int)96" ! rtph264depay ! decodebin ! xvimagesink<br>
<br>if you have a depayloader, you don't need the parser. However, the issue was the place you've set the "port" property.<br><br>btw unless you have a light-speed machine you'll see frame drops. In such a case, relaxing the buffers lateness constraints on the xvimagesinksync will help (max-lateness=10000000000). I don't suggest you to set sync=false there if one day you'll want to stream audio as well.<br>
<br>Another note: you don't need to use a decodebin in the receiving pipeline. Something like ffdec_h264 will be enough.<br><br>Regards<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
