It clearly says that ""no property "config-interval" in element "rtpmp4vpay0""" , that means you should not use this property. <div class="gmail_quote">On Wed, Feb 2, 2011 at 11:10 AM, <<a href="mailto:julien.lengrand-lambert@advansee.com">julien.lengrand-lambert@advansee.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Thanks for your previous message. I tried what you said, changing my command line to : gst-launch -v v4l2src ! video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! mfw_mpeg4encoder ! rtpmp4vpay config-interval=2 ! udpsink host=192.168.0.10 port=1234 Unfortunely, I get the error message WARNING: erroneous pipeline: no property "config-interval" in element "rtpmp4vpay0" I may not have the last version of gstreamer cross-compiled, hence a gst-list-mm give me 0.10. Could you say which plugins and version are mandatory to get this option working?
