如何将Qt Phonon视频与OpenGL场景叠加? [英] How to overlay a Qt Phonon video with an OpenGL scene?
问题描述
我想用Qt Phonon Player播放视频并将其与OpenGL场景叠加，以使半透明的OpenGL对象在视频上方.我搜索了几个小时，但没有发现如何实现这一点的提示.英特尔的这一概念证明描述了我正在寻找的东西.
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.

能否更好地在LinuxOS上增加这种效果?使用compiz + opengl + qt吗?
Could or better how could this effect be inplemented on LinuxOS? With compiz+opengl+qt ?

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