grab frame

Archived from groups: microsoft.public.pocketpc.multimedia (More info?)

I can tell you (* you won't like it) that no, its not possible to
screen-grab from the WMV on the device.

If you have access to a PC at the time, you can use GAPI tools like
newmad's PDA screen capture utility to grab it that way I guess.

You'll not have much control over the timing though, so you'll
probably get a different frame than you desired unless you pause the
video first.

Not that I'm aware of (and I've looked).

There's no PPC directX or SDK components you could use. What the PPC
uses for screen redraws is a system called "GAPI" so you might want to
look up that.

I know it's been fairly well documented and people have SDKs and some
demo apps running off it. It's mostly used for games for higher speed
screen access, so you could start looking for game programming demos
and work from there.
