Hello!

I've developed an application that obtains a single frame from a video
stream (I'm using a webcam), and I've done it using the "video for
windows" API. This application works with NO problem in Windows XP
Professional, but in Windows XP Embedded, it hangs, telling me this:

"The instruction at 0x0055060c referenced memory at XXXXXX. The memory
could not be read"

This problem only happens when I try to grab a single frame. When it's
only displaying video, it works ok. In my Windows XP Embedded image, I
included all the components that should be necessary, but maybe I've
forgotten someone: Directx9.0, video for windows, windows image
acquisition. And of course, I've installed the drivers for the video
card. I've also included the macro component "Analog Television
Support", because I didn't know exactly what I was doing wrong, so I
decided to include a lot of components, but it didn't solve my problem.

Any advice will be very welcome!

Thanks in advanced!
 
Ok, I found the problem. I was trying to access to a data base, but it
wasn't ready, so the application failed in this point. I thought the
problem was caused by the video capture code, because I had been
suffering problems with the video card.

Everything seems to be fine now.

Bye!
