slow revVideoFrameImage

[Doug Lerner]

I am calling revVideoFrameImage periodically and sending the grabbed frame
over a socket. The problem is that the revVideoFrameImage command itself
takes a noticeable amount of time: 1/4 - 1/2 second on my machine, 1 second
or more on slower machines.

In this app, at the same time people are doing other things, like text
input, etc. But during revVideoFrameImage everything else stops.

Is there a way of not having revVideoFrameImage itself hog the whole cpu
when it does its frame grab?

Thanks,
