Media Controllers (mediacontroller.h)
Functions to control media playing.
This file defines the Media Controller service, which provides functions for controlling the playing of media files.
Media Controllers allow you to connect to the Now Playing service to determine what content is currently playing. It also allows you to submit requests to control playback for the current, active media player in the system.
Devices have two default controllers on the system. One is tied to the physical buttons on the device and another tied to the Now Playing UI that appears when the user taps the now playing indicator in the status bar.
