OpenCV webcam capture problem

Question

I\'ve installed OpenCV 2.2 and now I can\'t get webcam capture to work. It worked ok in 2.1. OpenCV detects a webcam, doesn\'t report any errors or warnings, but each frame

Answer 1

I had the same problem. I figured that it might be the settings on my camera, because I was supposed to have an input of 640x480px (which I could not adjust) and I could not adjust the permissions for the feed. So I installed a virtual webcam, which pretty much resolved both issues. I got an input dialogue, chose the virtual camera and it worked. I managed to set it to 640x480 in the app too.

My virtual camera was called ManyCam, but it looks like it is made for teenage girls, wanted me to install 3 other apps and I'm still not sure weather it doesn't come with 'complementary' trojans.

However, it lets you adjust colors, hue, contrast etc. and other stuff you might need for testing.
