I am developing the desktop app based on win 10 with windows SDK. My computer hardware is a 2019 Mac book: i9-9880H CPU @2.3GHz, 16G mem, x64. The official zoom application works well. But my app with SDK shows back display for my own video. I checked the win 10 privacy for camera and it should be OK. I checked the camera with other apps, and all of them works well.
It worked well before yesterday. Actually I encountered such issue before and resolve it with reboot. But now it can not works. I use my another mac to check my binary, it works well. I test my Mac with windows on the go version on the same mac and it is the same issue.
I obsered that the official zoom app show the video from black to video for about 5~10 seconds.
I test win 10 1903 and 1909(should be autaum version in 2019). I test win SDK demo and demo v2. They are same issue.
