However, I've developed my own set of capture and video display classes. A complete application that just captures video and draws it on screen in real time: http://code.google.com/p/livepro/source/browse/trunk/devel/app-template/MainWindow.cpp#28 (That app demos both using OpenGL directly and using a QWidget to render video.) The low level capture under Linux is done with V4L: http://code.google.com/p/livepro/source/browse/trunk/gfxengine/SimpleV4L2.cpp Which is handled by the CameraThread (which uses libav on windows to capture): http://code.google.com/p/livepro/source/browse/trunk/gfxengine/CameraThread.cpp And the video is rendered using a GLVideoDrawable: http://code.google.com/p/livepro/source/browse/trunk/gfxengine/GLVideoDrawable.cpp (For actually using that googlecode project, see http://code.google.com/p/livepro/wiki/QuickStartGuide) Regards, Josiah > ** > > Any help and suggestion are greatly appreciated,**** > > Zen**** > > _______________________________________________ > Interest mailing list > Interest@qt-project.org > http://lists.qt-project.org/mailman/listinfo/interest > > -- Josiah Bryan 765-215-0511 josiahbr...@gmail.com
