Set the frame rate using leapuvc

[abdedixit]

Hi,

I am trying to use leapuvc to control the frame rate of the leap motion controller. The PDF documentation LeapUVC-Manual.pdf says that the gain control (uvc_set_gain) is multiplexed, and controls the analog gain, FPS ratio and dark frame interval. It then gives the selector bits and a formula for the PACK_VALUE, but it is not clear to me how to set the frame rate.

I wanted more clarity on the following:
(a) What is the FPS ratio? The documentation specifies it adjusts the framerate as a proportion of the maximum for the configured resolution, but I don't know what these maximum values are for each resolution.
(b) How do we set the FPS ratio independent of the analog gain and the dark frame interval?

Please can someone answer the above with examples? Thanks in advance.

Best,
AB
