Problem executing Directshow application
I am a newbie to DirectShow APIs. I have .NET and DirectX9.0 SDK installed into my Inspiron 600M laptop.I am trying to run a code that captures frame from usb webcam(Logitech Quickcam 4000 Pro). The code successfully grabs frame from other laptops as well as desktops but it fails doing so from my machine.
Surprisingly, if I try running EXE only that runs like charm on other machines, it fails on mine. Is it something related with webcam/driver?
the callback stucture is defined as following
typedef struct _callbackinfo
{
double dblSampleTime;
long lBufferSize;
BYTE *pBuffer;
BITMAPINFOHEADER bih;
DWORD biSize;
} CALLBACKINFO;
CALLBACKINFO cbInfo={0};
cbInfo.pBuffer value is NULL while grabbing is done. Which is not the case with other machines.
Any help will be appreciated.
