Give us as much detail as possible regarding the issue you're experiencing:
This is a question rather than an issue. Is it possible to play a live video feed within a Unity build for the ML2 from an external source such as a laptop, camera, twitch stream, or anything else?
It is possible to play video feeds on the Magic Leap 2. We do not limit this functionality. For example, you can use the Unity Video player component or use the Unity WebRTC package to stream video over WebRTC. You can also try building or using other plugins. Note, the plugins will need to support Android x86_64 and Vulkan.
