Player
Multimedia

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.

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.

and the media packet is available until it's destroyed by media_packet_destroy().
The packet have to be destroyed as quickly as possible after rendering the packet
and all the packets have to be destroyed before player_unprepare() is called.

Since :
2.3
Remarks:
This api will trigger the seeking operation on player instance. Normally application need to wait for player_seek_completed_cb() before calling it again. Otherwise it will return PLAYER_ERROR_SEEK_FAILED. Please note that if application is playing external media data via player_set_media_stream_info(), then consecutive calling of this api will always success and no need to wait for player_seek_completed_cb() before next calling of this api.(since_tizen 3.0)
Even if you don't set visible to true by calling player_set_display_visible, the video will be shown when the _seek_completed cb is invoked.
In case of non-seekable content, it will return PLAYER_ERROR_INVALID_OPERATION. If application ignore this error, player will keep playing without changing play position.
Parameters:
[in]playerThe handle to the media player
[in]millisecondThe position in milliseconds from the start to the seek point
