I did an update and after that I kept having 3 of 6 cameras get scrambled. Restarting the cam would fix for a couple hours. I rolled back to 52510 and same result. I stopped running it as a service, and it seems OK. Does anyone have a plan for this?
Interesting. Whenever I see corruption, it specifically does not affect Dahua cams, and it is 100% pure rainbow corruption, unlike yours where some of the normal detail is still there. Anyway, hardware acceleration is typically involved. Which (if any) kind of hardware acceleration are you using? If it is Intel, know that there are 3 different Intel options, and currently in the latest 6 or so versions the best choice is "Intel + VPP".
I don't know enough about the internals of Blue Iris to know how running in or out of service mode might affect it.
Have you tried 5.2.6.3 ? So far my issue hasn't returned and it affected 3 of my cams (all Dahua) different models. Note: I do not run it as a service though but mine was doing this anyway.
