Hi, I am trying to use the camera to capture frames in a low light environment. The camera is a NoIR OV5647. The actual maximum value of exposure_time_absolute=10000 is not enough to get a good image. When I use the raspivid command, values of 500000-2000000 (0.5-2s) results in fine image.
I did some fiddling in the settings, but I couldn't get anything better. The default settings that I am using is attached in the image.
Is there a way to change the settings to get the desired shutter speed/fps needed in this case? Thanks a lot

The problem lies with the v4l2-ctl, which is build to generic purposes and do not support all camera functionalities. And make sense since it is oriented to video feeds.
