Tizen Native API
|
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.

- Parameters:
-
[in] player The handle to the media player [in] latency_mode The latency mode to be applied to the audio
- Returns:
0
on success, otherwise a negative error value
