Hi, After patching the kernel, the rate that images are captured from the camera reduce by a factor of 2.5. Here are a list of frame rates I have tried followed by the resulted frame-rate: 10 fps --> 4 fps 15 fps --> 6 fps 25 fps --> 10 fps 30 fps --> 12 fps Note that all of the rates are consis

Actual framerate is always divided by 2.5
