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.

enum player_display_type_e

Enumeration for display type.

Since :: 2.3

In case of using PLAYER_DISPLAY_TYPE_OVERLAY_SYNC_UI, the video is rendering in full scale in the rendering area.
To change the video rendering position, use UI API functions like ecore_wl2_subsurface_exported_surface_move(), ecore_wl2_subsurface_exported_surface_resize(), ecore_wl2_subsurface_exported_surface_transform_set(), ecore_wl2_subsurface_exported_surface_show() and ecore_wl2_subsurface_exported_surface_commit().
player_set_display_mode(), player_set_display_rotation() and player_set_display_roi_area() cannot be used and PLAYER_ERROR_NOT_AVAILABLE is returned if they are used.
Exported shell handle must be obtained by ecore_wl2_subsurface_exported_surface_handle_get() from Ecore_Wl2_Subsurface.
Then the exported shell handle should be set with player_set_display().
To render the first video buffer, commit by ecore_wl2_window_commit() after player_prepare() of Ecore_Wl2_Subsurface.
Always commit with ecore_wl2_window_commit() with parent surface when the UI changes and the video needs to be synchronized.

Since :: 5.5

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

[in]	user_data	The user data to be passed to the callback function

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

Return values:

       ...
       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 seek position in nanoseconds for playback, asynchronously.

Since :: 5.0

Remarks:: This function will trigger the seeking operation on player instance like in the case of player_set_play_position().

(Since 5.5); This function could be unavailable depending on the audio codec type and this will return PLAYER_ERROR_NOT_AVAILABLE. (Since 5.5)

Parameters:

[in]	player	The handle to the media player
[in]	enabled	The new replaygain status: (`true` = enable, `false` = disable)

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

Return values:

int player_set_sound_stream_info	(	player_h	player,
		sound_stream_info_h	stream_info
	)

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:
http://tizen.org/feature/multimedia.player.stream_info
If this feature is not supported, the stream_type of the player is fixed to the SOUND_STREAM_TYPE_MEDIA.

Parameters:

[in]	player	The handle to the media player
[in]	stream_info	The sound manager info type

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

Return values:

PLAYER_ERROR_FEATURE_NOT_SUPPORTED_ON_DEVICE	Unsupported feature

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

See also:: sound_stream_info_h; sound_manager_create_stream_information(); sound_manager_destroy_stream_information()

Example

       #include <player.h>
       #include <sound_manager.h>

       ...

int player_set_uri	(	player_h	player,
		const char *	uri
	)

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

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
