Webcam programming SDK and documentation especially about for controlling pan, tilt, zoom capabi
Hi everyone
I'd like to capture video frames and tracking in some features in video frame images. But I don't have enough experience about programming webcams to do this operations. Especially How can I control pan, tilt and zooming capabilities of webcams through DirectX SDK ? Are there any documention and Know-how in the web ?
Thanks for your interest
Sincerely
Cem
Cem,
I would recommend that you start by downloading the DirectX SDK 9.0 and playing with GraphEdit which is a graphical program you can use to view the various available filter sources. For web cameras check out Capture Devices. Depending on your camera they may have exposed the pan, tilt control via the OLE property bag interface. If so then you can start to have a little fun by right clicking and selecting filter properties. If not well then you'll have some more digging to do. Either way you will most likely be able to capture screen shots using the FrameGrabber filter almost all web cams support Direct Show directly or are Windows Media Device complient. I hope this gets you started in the right direction.
Dear Chris,
First of all thanks for your interest in my problem an your reply, I installed DirectX SDK August 2006 but I can not find any executable regarding to the GraphEdit program except GraphEdit.jpg file inside the SDK folder. Do I need to build it otherwise there is no prebuild binary file about this utility program inside SDK ?
Sincerely
Cem
