FPS has no effect #5

I'm setting various (allowable) frame rates (FPS), but I don't notice a 
difference. FPS=1 and FPS=24 appear to give the same results. I tried a couple 
of different cameras without luck. How could I check for sure that v4l is using 
the correct frame rate?

I'm sorry for jumping to conclusions all of the sudden. The FPS work, but only 
if the camera supports it (which varies with resolution). Use "guvcview" to see 
what fps are supported at a particular resolution.

Hmm.. I see.  Actually the whole project was born to variate that parameter, 
but we're basically wrapping V4L, which could be -perhaps- less effective than 
specific drivers?
