[SDL] Frame Grabbing in SDL

[Wuschelchen at kaffeeschluerfer.com]

Hi all,

in several posts i've read that with SDL it is possible to implement readout of frame grabber cards.

I'm writing a bigger application with the Qt toolkit on Windows XP using the MinGW compiler. One important part of the application is to grabb a video stream from a PCI grabber card and analyse this.

For frame grabbing and visualisation i would like to take the SDL package in order to keep the code as system independent as possible.
The problem is that I'm not very experienced with SDL and don't have much idea how to start. The documentation doesn't give a real hint to the solution of this problem. :-(

It would be really great if someone could help and tell me how to realize this, especially how to choose and initialize the driver (resolution, color depth, frame rate...), how to capture a picture out of the stream, how to readout this into an array for example and how to display it. A complete code example (if someone has) would be absolutely perfect :o)

Best regards,

Tina
