I've tried linking my pads backwards, working from my bin's src ghost 
pad to the video decoder src, which is then linked to my h264 stream 
parsers src, which is then eventually linked on the other side to my 
bin's sink ghost pad.  I have also changed behavior so that it happens 
during transition from NULL->READY instead of READY->PAUSED, but the 
problem still occurs.

I should probably add that this is all done from inside decodebin2 which 
is parented by playbin2.

Can data flow through pads from an element that is in the READY state?

Thanks
