How can use V4L2 command to control the mipi sensor gain at jetson TX1 R28.2?

Does the gain command can run below function?

case TEGRA_CAMERA_CID_GAIN:
		err = imx219_set_gain(priv, ctrl->val);
		break;

hello sensor_test,

you could access your camera sensor with argus_camera instead,
there’s user-interface for you to input sensor gain settings directly.
thanks

Where have the argus_camera source code?

hello sensor_test,

you should install the multimedia API package through the JetPack installer.
please search “L4T Multimedia API Reference” and also get the documentation from Jetson download center for reference, thanks
