Why can't you set the mtu as an option before starting the pipeline? <div class="gmail_quote">On Thu, Feb 14, 2013 at 3:27 PM, johnwesting <<a href="mailto:john.blank.westing@gmail.com" target="_blank">john.blank.westing@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I need help. I have been working on this GStreamer project for weeks and constantly get stuck on GStreamer related issues and I don't know what to do. The documentation online is not thorough, and the Q&A on this forum are hit or miss helpful. I feel very alone. What I want for the most part seems so simple. GStreamer must have a way to accommodate what I am doing. I have a Base Transform Encode element, a Base RTP Payload element, and a Base Sink Element which communicates with a remote device. When the the Base Sink Element receives the set_capabilities() notification it connects to the remote device using the fixated capabilities of the Base Transform Encode element. After connection succeeds the remote device tells the Base Sink Element the desired MTU. The Base Sink Element then passes that MTU to the RTP Payloader element. All of that works fine. The problem is that the handle_buffer() function of the Base RTP Payloder element is called --before-- the MTU is set. How can I pause the pipeline while the Base Sink Element waits for the MTU? -- View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/Begging-For-Help-tp4658540.html" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/Begging-For-Help-tp4658540.html</a> Sent from the GStreamer-devel mailing list archive at Nabble.com. _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div>
