I'm also on 5.0.9.3 x64 running Windows 10 on an HP ProDesk 400 G4 Desktop Mini, i5-8500T. Last night as I was watching a front camera the video froze as somone was walking up my driveway. Now all 6 "Amcrest IP8M-T2499EW" cameras will only show a freeze frame when I click on them. The frozen frame is up to date within a second or 2, but it will not display live video. Streaming to my phone or any computer's browser works fine. Even using a browser on the computer running
Blue Iris displays Live Video. But the BI console will only show the frozen first frame of the Live Video. Motion triggers are recorded, as well as the 2 cameras that record 24/7. If fact everything seems to be working fine except that the console suddenly stopped displaying live video. As I cycle through the cameras, I do get a fresh updated single still frame for every camera. Multiple reboots and restarts of Blue Iris give the same results each time. Everything had been perfect for months and now suddenly I can't monitor the live feeds from the cameras.
This is my first post and I'm not sure if I should have started a new thread, but it sort of seemed like the same problem. I have no answers.
