Enables pan/tilt/zoom control of the device, if compatible.
This will trigger a new permission popup though.
Can be added to a guest's URL in a room. Then the director can manually change pan, tilt and zoom for the guest's camera via the video settings menu.
Can also be added to a simple push link, then you can change pan, tilt and zoom in the video settings. To allow a viewer to control PTZ directly, add &remote to both the sender and viewer links (optionally with a matching passcode).
The dedicated PTZ controller is available at: https://vdo.ninja/ptz.html
ptz.html supports additional URL setup flags (stage mode, preview controls, overlay options). See the dedicated parameter list in: PTZ Remote Control
The dedicated PTZ surface and API also support remote output transforms: remoteMirror (aliases: mirror, mirrorGuest) and remoteRotate (aliases: rotate, rotateGuest).
Chrome blocks PTZ changes when the sender page is hidden. Keep the sender visible on screen if controls appear to do nothing or you see "page is not visible" errors.
