Description Nicolas Dufresne (ndufresne) 2014-05-29 15:07:45 UTC 
There is a warning due to miss-ordering of event when using the mixer. Does not seems to break for simple case, but we know it can confuse certain stream synchronisation code.

gst-launch-1.0 videotestsrc ! video/x-raw,format=RGBA ! m. videotestsrc pattern=18 background-color=0 ! video/x-raw,format=RGBA ! m. glvideomixer name=m ! glimagesink
