RPI Camera v2 NoIR - applying the imx219_noir tuning file with motionplus?

[hibit74]

Hello all - I wonder if anyone can point me to how I would apply the tuning file when using motionplus?

I have motionplus running nicely here with the camera configured as a libcam device in the motionplus config file - but with the red hue to the image. The camera is detected as a IMX219 in list-cameras as I understand there is no hw difference between the standard and noir versions of the v2 cam.

Pre-libcam I was able to set awb to isgreyworld, and more recently using libcamera alone (without motionplus) I can set the config file when calling libcamera on the command line.

Is there a way to configure the tuning file to be used within libcam_params in the motionplus config that I am missing?
Or can I specify the tuning file at boot before motionplus is run?

Appreciate any pointers, many thanks

Yes, you can set "most" of the libcamera options via the libcam_params option in Motionplus. The options available to be set are in the Motionplus documentation. For example, to set the AWB to custom, the Motionplus parameter would be specified like the following:

libcam_params AwbMode=7

As for which parameters to set to what, that is a libcamera thing. This is the libcamera api documentation reference. I didn't see "isgreyworld" so you'd need to experiment to find the equivalent.

Additional Note: This discussion was moved from the Motion repository since libcam_params is only applicable to Motionplus.

Thanks for getting back to me Mr Dave and for moving this to right repo. To add a little more background.
From the command line if I execute motionplus normally as a service with my motionplus config set to expect a libcamera device it runs fine, jsut produces the red-hued output. However, if I execute this at the command line:

libcamerify --tuning-file /usr/share/libcamera/ipa/raspberrypi/imx219_noir.json motionplus

This runs but produces a black video stream as libcamerify (I think) presents a v4l device to motionplus, which my config doesn't expect (it is set up for libcamera device). To note, running the likes of:

libcamera-hello --tuning-file /usr/share/libcamera/ipa/raspberrypi/imx219_noir.json motionplus

Works fine and applies the tuning file, fixing the red hue.

What I can't find a way to do, is run motionplus whilst also applying the tuning file. Should I set me motionplus config to expect a v4l device, use libcamerify to 'wrap' motionplus at the command line? I tried this but couldn't seem to make that work.

You'll need to change whatever is inside the json file into parameters for the libcam_params
