When using the ClickShare CX-series Base Unit with a peripheral camera in conjunction with a specific range of AMD-powered laptops certain issues with the camera feed image may arise during video calls.
Following are the symptoms:
- Yellowish tint or distortion in the displayed image
- Black flashes appearing on the screen intermittently
- Complete absence of image from the connected camera (i.e. camera failing to show any image altogether)
Here is an overview of what Certified Peripherals can potentially show the issue in combination with an AMD Laptop.
Root Cause:
We have investigated the root cause of these symptoms and have come to the conclusion that the AMD video driver crashes when the chroma subsampling changes in the video stream when that is required from the peripheral.
Solution:
Please only verify with latest AMD drivers and ClickShare CX Base Unit firmware version and see if this resolves the issue.
We have reached out to AMD in order to collaborate on the best possible fix for this issue. AMD has developed a fix but can't push it to the laptop's OEM.
Currently, along with AMD, we are reaching out to various OEMs and asking them to include the fix in their update packages.
