Hi-
When porting my application to version 2.65vrml, I have encountered
intermittent video problems. The video works for a while and then it
freezes or has multi-second delays for each frame. The previous versions of
the toolkit works with the same hardware which suggests that it may be a
software glitch. Is there a fix/patch for this problem? Did anyone else
have this problem?
Best,
Abhilash.

Hi
I faced this problem when I had connected a webcam with automatic
controls such as exposure or gain. I believe that some processing was
carried out by the embedded video image controller. You can fix this
problem (if so) by disabling these automatic controls. Some camera
drivers have control dialogs to set up the image format, brightness,
contrast, etc...
Best wishes
