@Alex-Kushleyev Here is a copy and paste of the the voxl-camera-server.conf file that you requested. It won't allow me to attach the file itself.

/**

• voxl-camera-server Configuration File
• Each camera has configurations for up to 4 HAL3 streams:
• • preview stream for raw unprocessed images from CV cameras
• • small_video 720p (ish) h264/h265 compressed for fpv video streaming
• • large_video 4k (ish) h264/h265 for onboard video recording to disk
• • snapshot ISP-processed JPG snapshots that get saved to disk
• on QRB5165 platforms (VOXL2 and VOXL2 mini) you can only have 3 of the 4 enabled
• This file is generated from default values by voxl-configure-cameras.
• Do not expect arbitrary resolutions to work, the ISP and video compression
• pipelines only support very specific resolutions.
• The default video compression mode is cqp or Constant Quantization Parameter

@Alex-Kushleyev this seems to have a positive effect but its not working perfectly and it doesn't work all the time. Inside on the workbench, I noticed that when I restart the voxl-camera-server it immediately shows up pink, but as soon as I lift the vehicle off the ground it seems to adjust settings and the color comes out closer to true color and what we are looking for (I have a video that show the behavior, but I am not sure how to post it here).

However, I took the vehicle outside to perform a test and I was not able to get the pink hue to go away. I tried restarting the camera server and tilting it around hoping it would auto adjust the settings, but I didn't have any luck. Do you have any other suggestions?

Before Restart

After Restart

After Lifting which causes auto-adjust

Re: Hi-res IMX214 (M0024-2) Color and Stuttering Issue

I went through the process linked in the above thread and successfully got rid of the green circle found in the center on the picture, but I am still dealing with pink/warm tones dominating the picture. This is causing issues with our color detection algorithm, and we are hoping for a correction to produce true colors.
