Qt and vsync / breaks

Question

Does anyone know a simple way to force vsync in Qt when displaying an image on QLabel? Basically, I transfer the stream of images from the processed video clip (therefore, without using Phonon multimedia), and the frame rate is very high. Unfortunately, this breaks a lot.

Any help is greatly appreciated.

Try using QtOpenGL. You can implement your widget over QGLWidget. It will be displayed using opengl, which will depend on vblank if you set this option in your os.
