Computer A: win7 64, Intel 4Gen i3，4g memory
Edge + ipcamera, The delay is 20ms.
vscode+python3.8+opencv4.10, The delay is 20ms.
It’s ok.

Computer B: win10 64, amd 5900x, 16g memoy
Edge + ipcamera, The delay is 20ms.
But, vscode+python3.12+opencv4.10, The delay is 1 second, too long.

Host: Computer B + Vmware: win7 64
Edge + ipcamera, The delay is 20ms.
But, vscode+python3.12+opencv4.10, The delay is 1 second, too long.
