Hi,
I am using WinCE6.0 R3 OS and USB Camera Driver.It download from microsoft's website. My platform is S3C6410 Development Bord.
The Driver supports two mode: UNCOMPRESSED or MJPEG.
My question :
1 I used UNCOMPRESSED mode,the 'CameraDshowApp.exe("D:\WINCE600\PRIVATE\TEST\MULTIMEDIA\DIRECTX\DSHOW\CAMERA\CAMERAAPP") worked well,could capture and snap picture.But, it only supported 176*144 pixel. It's too small, Can you give me some
help?
2 I used MJPEG mode, the driver can support follow pixels:
MJPEG Format[0] Width: 640, Height 480, Max Buf: 0x96000
MJPEG Format[1] Width: 160, Height 120, Max Buf: 0x9600
MJPEG Format[2] Width: 176, Height 144, Max Buf: 0xc600
.........
MJPEG Format[11] Width: 800, Height 600, Max Buf: 0xea600
But When i run the App(CameraDshowApp.exe), Driver output a exception:
Exception 'Data Abort' (4): Thread-Id=07be01ea(pth=855e5240), Proc-Id=07bd01ea(pprc=83ce5428) 'CameraDshowApp.exe', VM-active=07bd01ea(pprc=83ce5428) 'CameraDshowApp.exe'

It can't support capture and still. Someone had the same questions,but not give the Solutions.
Please give me suggestion.
