For example: <pre>gst-launch videotestsrc ! x264enc ! rtph264pay ! udpsink port=5000 -v ... </pre> <pre>/GstPipeline:pipeline0/GstRtpH264Pay:rtph264pay0: seqnum = 33460</pre> <pre>/GstPipeline:pipeline0/GstUDPSink:udpsink0.GstPad:sink: caps = application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\"Z01AFeygoP2AiAAAAwALuaygAHixbLA\\=\\,aOvssg\\=\\=\", payload=(int)96, ssrc=(uint)2406338994, clock-base=(uint)156724985, seqnum-base=(uint)33460 ... </pre> The -v printed out the caps. I can successfully receive it by running: <pre>gst-launch udpsrc port=5000 ! "application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)\"Z01AFeygoP2AiAAAAwALuaygAHixbLA\\=\\,aOvssg\\=\\=\", payload=(int)96, ssrc=(uint)2406338994, clock-base=(uint)156724985, seqnum-base=(uint)33460" ! rtph264depay ! ffdec_h264 ! fpsdisplaysink sync=false</pre> And yes, this means that the receiver pipeline is fixed to the sender pipeline's resolution and characteristics. Changing something on the sender will require a new pipeline on the receiver. If this is a problem for you, you might want to try using mpegtsmux or a smarter protocol like RTSP.

Take out the jitter buffer. Specify the host in addition to the port for both pipelines. It might force IPv4 vs. IPv6 (there have been issues). Set higher logging levels and/or get a packet capture to see if the problem(s) is in the transmit or receive. </div> <div class="gmail_extra"> <div class="gmail_quote">On Tue, Apr 15, 2014 at 3:19 PM, Craig Routledge <<a moz-do-not-send="true" href="mailto:web@craigroutledge.com" target="_blank">web@craigroutledge.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello everyone, I'd like to send a video stream created by a Logitech HD ProWebcam C920 to another computer. The camera generates its own H264 stream. There have been similar posts on the mailing list before, but I couldn't find anything that seemed to work. I started by testing gstreamer's ability to parse and display the stream. gst-launch-1.0 v4l2src ! video/x-h264,width=640,height=480,framerate=30/1 ! h264parse ! avdec_h264 ! xvimagesink sync=false which works fine. I then tried to stream over a network using RTP, sending and receiving on the same computer, gst-launch-1.0 v4l2src ! video/x-h264,width=640,height=480,framerate=30/1 ! rtph264pay ! udpsink port=8554 and, in another terminal window, gst-launch-1.0 udpsrc port=8554 ! application/x-rtp ! rtpjitterbuffer ! rtph264depay ! h264parse ! avdec_h264 ! xvimagesink sync=false This doesn't generate any errors, but doesn't display anything either. Here is the standard output for both commands, Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstSystemClock So, what am I doing wrong? _______________________________________________ gstreamer-devel mailing list <a moz-do-not-send="true" href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> <a moz-do-not-send="true" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote> </div> </div> <fieldset class="mimeAttachmentHeader"></fieldset> <pre wrap="">_______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> </body> </html>
