a) Thank you very much, Klen.

b) krk969: Do you mean http://opencv.willowgarage.com/docum...cpp/index.html ? I also read parts of "Learning OpenCV: Computer Vision with the OpenCV Library", which seemed quite helpful.

The conventional resources are:
http://doc.qt.nokia.com/qt-maemo-4.6/classes.html
http://www.khronos.org/opengles/sdk/docs/man/
http://gstreamer.freedesktop.org/documentation/

Hope that helps. Since the main code chunks are taken from the tutorials and contain no doxygen documentation themselves, there shouldn't be any further resources imho.
