OK, so this is about the simplest, most reliable plugin, and it is failing. Clearly the plugin isn't at fault, but something in my system is. The pipeline is:<br><br>udpsrc port=$1 typefind=true ! 'application/x-rtp,media=video,payload=96,clock-rate=90000,encoding-name=H264' \<br>
! rtph264depay ! video/x-h264 ! ffdec_h264 ! ximagesink sync=false<br><br>I am running on a brand-newly created VirtualBox VM RHEL 6.3. Gstreamer 0.10.30, good-plugins version 0.10.25 running. This is one of my standard test scripts that I can always count on, but most of my work is on CentOS 6.0 and not in a VM. Regrettably, I don't have an option here. IPTables is off. Does anyone <PLEASE> have any ideas what to look at to resolve this problem?<br>
