hi all:
I’m writing USB driver for digital camera, and it works
well on 98 platform of my pc. you can adjust brightness,
contrastness etc. in DirectShow standard dialog when
clicking “video capture filter…” menu in AmCap or other
“preview” software.
But this dialog for property adjustment can’t be created
and “pop-up” when it works on xp platform of my pc and on
other person’s pc. When you click “video capture filter…”
menu in AmCap, nothing happens, no dialog pop-up, which
means we can’t adjust VideoAmpProperty on these platforms.
My driver is coded according to the sample of usbintel in
98DDK, and the interface between driver and DirectShow is
standard. So I’m puzzled where the problem exits.
Is there anyone can help me?
thanx in advance
Rex
