USB Camera software
USB Camera software
I need a software that can grab an image from an USB camera every 5:th minute. (Watch the paint dry SoftWare !!!)
Features :
* Able to select one of my USB cameras.
* Able to select video format.
* Able to select time delay between 1 s and 1 hour.
* Able to run the SW for 48 hours or more.
* Two ore more applications of the SW most be able to run simultaneously with different USB cameras.
* Every image is saved as jpg or bmp (numbered filenames).
I prefer it if it is one ".exe" file and no installation (other than VFW) required.
If there is source code for Delphi 5 using vfw.pas included I’ll add another 300 points.
I have tested one freeware SW that handled all of the above features but I have lost it.
** I’ll bee out of the office until Friday so don’t expect any points or comments from me until June 14. **

Many thanks for the answer !
200 p for the solution and extra for the source code 300 as I promised.
I wonder if You can implement a onFrame event in the component. I need to do some image computing in the preview window in another application.

Thanks again

yes you can .. but what are you using now ?
vfw ? if so then you set a FrameCallback
you'll get that callback only if at least one of the pixels of the preview window is visible and NOT recording !
otherwise nothing ...
if you're using DS then you have to implement an ISampleGrabber interface
for that you need DX8 or newer

with vwf you need to have the capture window visible
even if another window is displayed over it you will not be able to grab frames
I use DirectShow and it works fine anytime :)
the only downside is that you'll need DirectX 8 or later
a fine video capture component is TVideoCapture from Egor Averchenko
you can get it at www.torry.net/video.htm
another great set of directshow components is DSPack
you can get that at www.progdigy.com
I use TVideoCapture in my video survailance project and I capture from multiple cameras on one computer and it works great
