The NDI HX Camera app is quite good but lacks some important features. It would be great if it matched the native Camera app, such as locked exposure and the ability to pan while zoomed. A cross-platform plugin to control the camera directly from the main streaming device (e.g., a laptop) would also be very useful.
I should add that I’m a novice using NDI HX Camera for church live-streaming, so these features would greatly help simple users like me. I’m not sure if these are possible or if solutions already exist—if anyone knows, please share.
