Thanks so much for the reply! It helped give me the motivation to keep working on finding a solution!
Okay, so I have managed to find a "fix" for the problem, so I thought I'd let you know the steps/info to hopefully help narrow down the issue and assist anyone else that comes across this.
My uname -a for the non-working/bugged system is:I saw a reply on that post regarding v4l2 controls and thought I'd give that a go before downgrading the kernel and potentially creating more issues. This seems to have identified what the error is, but not necessarily what has caused it.
My capture device is just a cheap grabber from an HDMI splitter out of my PC. Most people using HyperHDR will be using different grabbers, so I wouldn't assume that any one device is causing the issue. An example of a commonly used one is the "ms2130."
When I ran: (for my USB grabber), it also returned the exact same values as the user reported in the other thread, suggesting that these same incorrect "default" values might be shared across all users encountering the issue.
when ran the following command The "inverted" color issue was immediately fixed.
However, when I click "HDR to SDR tone mapping" within HyperHDR, the issue comes back, so it doesn't appear to be persistent. But that is a problem for when I next have time on my hands.
I hope this has been at least somewhat helpful, and thank you again for replying! Please let me know if I can provide any more info, and I will try and get it for you
