The Player API provides functions for media playback and controlling media playback attributes.

Required Header

#include <player.h>

Overview

The Player API provides a way to play multimedia content. Content can be played from a file, from the network, or from memory. It gives the ability to start/stop/pause/mute, set the playback position (that is, seek), perform various status queries, and control the display.

Additional functions allow registering notifications via callback functions for various state change events.

This API also enables collaboration with the GUI service to present a video.

State Diagram

Playback of multimedia content is controlled by a state machine. The following diagram shows the life cycle and states of the Player.

State Transitions

FUNCTION	PRE-STATE	POST-STATE	SYNC TYPE
player_create()	NONE	IDLE	SYNC
player_destroy()	IDLE	NONE	SYNC
player_prepare()	IDLE	READY	SYNC

Asynchronous Operations

All functions that change the player state are synchronous except player_prepare_async(), player_set_play_position(), and player_capture_video(). Thus the result is passed to the application via the callback mechanism.
