With the C++ API you can use QVideoProbe (http://qt-project.org/doc/qt-5.0/qtmultimedia/qvideoprobe.html). Though, with a camera source, it will currently work only on Linux with the GStreamer backend. The frames can be in any format, including an OpenGL texture, and you'll have to to convert it to a QImage yourself if it's what you want to do. You can also subclass QAbstractVideoSurface (http://qt-project.org/doc/qt-5.0/qtmultimedia/qabstractvideosurface.html). It will work on all platforms and you will be able to specify the format of the received frames with supportedPixelFormats(). You will also have to take care of showing the frames on screen youself... Yoann Lopes Senior Software Engineer - Digia, Qt Visit us on: http://qt.digia.com
