Desktop Videocam image capture library

[agraham]

By popular demand! This isn't finished but it is usable. This captures bitmaps from your videocam if you have one. Desktop and .NET 2.0 only.

EDIT : Version 1.1 with demo and help file posted. Can now save an image to a file and show continuous video.

EDIT : Version 1.2 with updated demo and help can now show two dialogs for the user to adjust camera settings if the capture driver implements this.

EDIT : Version 1.3 now has as a dialog missing unintentionally from version 1.2

None whatsoever. It uses VFW (Video For Windows) which is not implemented on the device You could try this http://www.basic4ppc.com/forum/addit...a-library.html Camera support on devices was almost non-existent until WM5.0.

I'll add single frame image saving in several formats and proper video in the next release. You could also use this in conjunction with my ImageEdit library http://www.basic4ppc.com/forum/addit...g-library.html which supports saving images

But that brings up the camera dialogue and requires user action!
I want my program to be able to spy on people without them knowing about it lol!

Ive been thinking theres a real issue here about the differences between window librarys and compact librarys. I wish pocketpcs could run the same stuff as desktops can.
Maybe WM7 will try and converge with Vista - Ive heard that miniWindows and gesture recognition using the vidcam will be in that OS - who knows.

Anyway another great library even if it is just for desktop! I think they should give u another medal!!
p.s. The wavegenerator demo went down well too!

Hi Andrew,
Recently, I came across your videocam library and prepared an application
that captures Moon and planetary images from a webcam mounted to a
telescope.
Thumbs up! All works as advertised.
Microsoft's AmCap or VidCap do the same thing, but the idea is to do it
yourself. And here your awesome library comes in very handy.
Are you still planning to add "proper video" (uncompressed AVI would be
sufficient for hobby astronomers).

Cheers
Robert

By "proper video" I actually meant the Preview On/Off in the demo. However it looks easy enough to add recording an AVI. I'll look at it soon when I have a few hours to spare to refresh myself on how video works in Windows.

Thanks a lot for your prompt reply, Andrew.
No rush on that. In the meantime, I save an image every second
and stack them using Registax for further processing.
