If any of you have suffered from frozen or repeating frames when running at 640x480 resolution, this is a possible solution.
I got the solution from the Youtube video listed above by searching for a “missing video pin” error that occurred when running an openframeworks app.

I downloaded manycam from here:

http://www.manycam.com/

Install without the norton or ask stuff obviously, then under Effects, Text over video
uncheck the “show manycam.com logo”

Then go to sources and select your camera. Click Force size and then 640x480. You can check improve quality if you want but I didn’t notice anything.

exit out and then try running an application that uses your eye cam.

So far for me, it’s stopped the freezing issue for
ITU GazeTracker
OpenCV
Eye Writer Project
FTR_BY_WLP

I don’t know exactly why it works but it works.

The image freezing, from my experience, has to do mainly with the speed of your machine, the DPC latency spikes, chosen capture resolution/framerate and the type of the USB controller on your motherboard.

The machine I was running on had only the mouse plugged in. 3.0ghz with 4 cores and doing nothing else. I guess I should clarify when I said freezing, I don’t mean reoccuring freezing. The camera runs smoothly for 3 seconds and then stops all together. I don’t know if this is correct but it’s almost as if the “bucket is full”. I’ve tested this on three computers, two windows xp and one with windows 7 64 bit.

The highest the test latency ever got in DPC checker was 176 microseconds.

This sounds like the issue I am currently having.. core2 quad with 6 gigs of ram.

it will run for a bit and just freeze.. or keep bouncing between the last couple frames.

Also, Try downloading the new drivers. (released yesterday). The driver stopped the initial freezing as well as after an allotted time.

yeah installed those earlier today.. same issue….
