--- Description of the Qt examples ---
- videooverlay:
Show how to use the videooverlay interface through Qt.
The video is displayed as normal 2D scene.
The window is dynamically resized to have the same size as the original video.
- mousevideooverlay:
Show how to use the videooverlay interface through Qt.
The cube is rotating when moving the mouse (+ click maintained)
- qglvideooverlay:
- qglwidgetvideooverlay:
Show how to use the videooverlay interface through Qt.
The cube is rotating automatically into a QGLWidget
- videovdieooverlay:
Show how to use the videooverlay interface through Qt.
The video is displayed as normal 2D scene.
The window is dynamically resized to have the same size as the original video.
