I’m seeing the same thing matty - I think.
configapp (the calibration app that shows you the camera video feed in X number of windows) is extremely slow, on the order of 1fps. I haven’t noticed it freeze/resume, but with that kind of responsiveness it’s hard to tell.
The other apps that come with touchlib seem to work just fine ( smoke demo, etc ) - so the touchlib library is reading the camera feed just fine, this leads me to believe the problem is a display issue (software rendering vs. XVideo extension), or a timing issue in the CV capture code
It’s usable if you’re patient enough to get your camera calibrated well, but that step is nigh impossible for me at the moment.
Just occurred to me that the actual touch calibration screen (with the red X’s) shows a debug window of the video feed, and that seems to be displaying at full FPS, the trouble is definitely something to do with touchlib’s display of the several video feed windows.
