How to overlay a Qt Phonon video with an OpenGL scene?

问题

I want play a video with the Qt Phonon Player and overlay it with an OpenGL scene, so that the semitransparent OpenGL objects are above the video. I searched for hours but found no hints how to realize this. This Proof of Concept from Intel describes what I am looking for.

How can this be realized? Which components are necessary for this?

Some posts which are similar to mine:

to clearify my intention here i found a picture what perfectly describes what i am looking for. This picture is from a Intel articel for a Hardware Feature of a Intel embedded graphic device (http://download.intel.com/embedded/software/IEGD/324707.pdf)

Could or better how could this effect be inplemented on LinuxOS? With compiz+opengl+qt ?

回答1:

referring the post Play a video with custom overlay graphics it should be possible. But there the solution is descriped really shallow.
