Dear Experts,
OS: WinEC7 , Platform: arm/freescale i.mx53 custom board, 512MB RAM
I am trying to use USB Camera driver in WEC7.
Here is the reference link which tell us how to use WCE6 USB camera driver in WEC7:

My usb camera works well in OMAP WinCE 6 platform.
But in WEC7, this usb camera only can work if I unselected VideoRenderer.
When I remove (unselected) Video Renderer in CameraDshowApp, I can capture still image and record video.
If I selected VideoRender in CameraDshowApp, it will show a still image on screen and suddenly turn off CameraDshowApp.
(CameraDshowApp is the default camera app that provided by MS, same app can work well in WCE6)
CameraDshowApp - unselected VideoRender

Could anyone tell me how to resolve this issue ?!! thx ~
