I'm using a Logitech c920, and when I use the cv2 python interface on OS X, I get 1920x1080 frames at 30fps, but when I boot into ubuntu 12.04 on the same machine, the same cv2 code captures 1920x1080 frames at 15fps. Any suggestions on what I can do to bump up the fps in ubuntu?

Try setting the fps: cv.SetCaptureProperty(capture, CV_CAP_PROP_FPS, 30.0);

Most of the webcams support max 30fps @ 640480 or 60fps @ 320240... Look at specs for your cam.

p.p. I also looked for high fps cam, but the only camera that does the job is from xBox live - 30fps @ 640*480

-1 : Since he just reported that he can actually get the 30fps for 1920x1080 resolution, this will not be the problem. Actually if he has this speed, then he is already using high speed capturing device.
