I use a pixelbender in my application to make a color key effect on a webcam bitmap. I noticed now that I get some delay when displaying the result on screen. There semms to be no big/visible difference between shaderJob (which takes about 20 to 30 ms until it is done) and shaderfilter. But I had some problems after using shaderFilter and getPixel (which gave me random results sometime).
Is it possible to use a webcam and pixel bender in flash w/o delay?
There was a Flex and Pixel Bender photobooth application that somebody wrote that seemed to work without any significant delay. http://www.happytoad.com/?page_id=116
I'm not sure why you'd get random results from GetPixel, that shouldn't happen. If you could come up with a consistent repro, I'd really love to see it so we could fix it.
