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.

Parameters:

[in] user_data The user data passed from the callback registration function

Precondition:: It will be invoked when the playback is completed if you register this callback using player_set_completed_cb().

See also:: player_set_completed_cb(); player_unset_completed_cb()

typedef void(* player_error_cb)(int error_code, void *user_data)

Called when an error occurs in the media player.

Following error codes can be delivered.

Since :: 2.3

typedef void(* player_interrupted_cb)(player_interrupted_code_e code, void *user_data)

Called when the media player is interrupted.

If the code is PLAYER_INTERRUPTED_BY_RESOURCE_CONFLICT, the player state will be one of PLAYER_STATE_IDLE, PLAYER_STATE_READY, or PLAYER_STATE_PAUSED. Application should get exact state by calling player_get_state().

Remarks:: This function must be called before calling player_prepare() or player_prepare_async().
A registered callback is called in a separate thread (not in the main loop).
The audio PCM data can be retrieved using a registered callback as a media packet and it is available until it's destroyed by media_packet_destroy().
The packet has to be destroyed as quickly as possible after rendering the data
and all the packets have to be destroyed before player_unprepare() is called.; If audio offload is enabled by calling player_audio_offload_set_enabled(), this function will return PLAYER_ERROR_NOT_AVAILABLE and this will not work at all even if this was called before enabling offload.; This function could be unavailable depending on the audio codec type and this will return PLAYER_ERROR_NOT_AVAILABLE.; If the content is encrypted or there are copyright issues with it, this function could be unsupported depending on the DRM policy.

Parameters:

[in]	player	The handle to the media player

       ...
       media_format_create(&a_format);
       media_format_set_audio_mime(a_format, MEDIA_FORMAT_PCM_F32LE);

int player_set_media_packet_video_frame_decoded_cb	(	player_h	player,
		player_media_packet_video_decoded_cb	callback,
		void *	user_data
	)

Sets a callback function for getting the decoded video frame.

Since :: 2.3

Remarks:: This function must be called before calling player_prepare() or player_prepare_async().
A registered callback is called in a separate thread (not in the main loop).
A video frame can be retrieved using a registered callback as a media packet.
The callback function holds the same buffer that will be drawn on the display device.
So if you change the media packet in a registered callback, it will be displayed on the device
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.; If the content is encrypted or there are copyright issues with it, this function could be unsupported depending on the DRM policy.

Sets the player's sound manager stream information.

Since :: 3.0

Remarks:: You can set sound stream information including audio routing and volume type. For more details, please refer to sound_manager.h; This function must be called before calling the player_prepare() or player_prepare_async() to reflect the sound stream information when the player is building.; This function is related to the following feature:

Example

       #include <player.h>
       #include <sound_manager.h>
       ...
       player_h player = NULL;
       sound_stream_info_h stream_info = NULL;
       sound_stream_type_e stream_type = SOUND_STREAM_TYPE_MEDIA;
       ...
       sound_manager_create_stream_information (stream_type, _focus_callback, use_data, &stream_info);
       player_create (&player);
       player_set_sound_stream_info (player, stream_info);

       ...

int player_set_uri	(	player_h	player,
		const char *	uri
	)

Sets the data source (file-path, HTTP or RTSP URI) to use.

Associates media contents, referred to by the URI, with the player. If the function call is successful, subsequent calls to player_prepare() and player_start() will start playing the media.

Since :: 2.3

Remarks:: If you use HTTP or RTSP, URI must start with "http://" or "rtsp://". The default protocol is "file://". If you provide an invalid URI, you won't receive an error message until you call player_start().; This function must be called before calling the player_prepare() or player_prepare_async() to build the player based on the URI information.; The mediastorage privilege(http://tizen.org/privilege/mediastorage) must be added if any video/audio files are used to play located in the internal storage.; The externalstorage privilege(http://tizen.org/privilege/externalstorage) must be added if any video/audio files are used to play located in the external storage.; The internet privilege(http://tizen.org/privilege/internet) must be added if any URLs are used to play from network.

Parameters:

[in]	player	The handle to the media player
[in]	uri	The content location, such as the file path, the URI of the HTTP or RTSP stream you want to play

Returns:: 0 on success, otherwise a negative error value

Return values:

PLAYER_ERROR_NONE	Successful
PLAYER_ERROR_INVALID_PARAMETER	Invalid parameter
PLAYER_ERROR_INVALID_OPERATION	Invalid operation
PLAYER_ERROR_INVALID_STATE	Invalid player state
PLAYER_ERROR_PERMISSION_DENIED	Permission denied

Precondition:: The player state must be set to PLAYER_STATE_IDLE by calling player_create() or player_unprepare().

int player_set_video_roi_area	(	player_h	player,
		double	x_scale,
		double	y_scale,
		double	w_scale,
		double	h_scale
	)

Sets the ROI (Region Of Interest) area of the content video source.

This function is to set the ROI area of video content to render it on PLAYER_DISPLAY_TYPE_OVERLAY display with current display mode. It can be regarded as zooming operation because the selected video area will be rendered fit to the display.

Since :: 5.0

Parameters:

[in]	player	The handle to the media player
[in]	x_scale	X coordinate ratio value of the video source area based on the video width size Valid range is 0.0~1.0.
[in]	y_scale	Y coordinate ratio value of the video source area based on the video height size Valid range is 0.0~1.0.
[in]	w_scale	Width ratio value of the video source area based on the video width size Valid range is from greater than 0.0 to 1.0.
[in]	h_scale	Height ratio value of the video source area based on the video height size Valid range is from greater than 0.0 to 1.0.

Returns:: 0 on success, otherwise a negative error value

Return values:

PLAYER_ERROR_NONE	Successful
PLAYER_ERROR_INVALID_PARAMETER	Invalid parameter
PLAYER_ERROR_INVALID_OPERATION	Invalid operation

int player_set_volume	(	player_h	player,
		float	left,
