You can switch to a different video scene (a different camera) or to a composite video scene (PinP/split) from the scene that’s currently selected.
Tap the camera scene, PinP or split scene you want to show next.
The scene you tapped switches to the output scene and is livestreamed.
At that time, a border is shown around the output scene to show that it’s livestreaming.
The video that’s currently livestreaming (output scene) is sometimes called the “program video”.
