Specifies the desired framerate. Is an integer in the range of 4-30.

- Specifies the desired colour order that should be delivered by read() and

- Only the native yuv420/yuv420p format is supported by the in kernel driver.

The compression parameter only applies to the Vesta & ToUCam cameras.

+leds
+ This settings takes 2 integers, that define the on/off time for the LED
+ (in milliseconds). One of the interesting things that you can do with
+ this is let the LED blink while the camera is in use. This:
+
+ leds=500,500
+
+ will blink the LED once every second. But with:
+
+ leds=0,0
+
+ the LED never goes on, making it suitable for silent survaillance.
+
+ By default the camera's LED is on solid while in use, and turned off
+ when the camera is not used anymore.

+ This parameter works only with the ToUCam range of cameras (730, 740,
+ 750). For other cameras this command is silently ignored, and the LED
+ cannot be controlled.
