SelectMediaDeviceCallback

interface SelectMediaDeviceCallback : MediaSyncCallback<P, R>

A callback invoked when a web page requests to select a media input device.

If there are no media input devices of the requested type (e.g., no video input devices are available), this callback will not be invoked.

Important: the engine will be blocked until the callback returns control.

If this callback throws an exception, the system's default media input device will be used instead.
