Hi,
I finalized my webcam capture module and think lots of people will have answer to many problems :
See VB.NET sources here : http://edid.free.fr/shared/webcam/index.php


That's VB.NET source. I work with XP Pro.
Three hard points :
- To get the maximum frames rate : 90 frames/sec (with Philips SPC 900NC PC Camera)
- To be able to change of camera in the same device (secret is in register database)
- To treat multiple image format (RGB24, I420 with DIB)

I can not get better than 15 frames/sec with 640x480 resolution, USB limitation ? If anyone has an idea...

Enjoy it.
