qmlglsink plugin problem

[Jani Koskimaa]

I managed to solve this. I had two issues. At first, I was compiling
gstreamer plugins against different version of Qt than I was using for my
application and qml example. After I fixed Qt version qml example start
working.

Second issue.. I was starting pipeline too early, before player window was
shown (openglContext doesn't exist then). I just need to delay pipeline
start.
