Tizen Native API  6.5

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.

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.

Sets a callback function for getting the decoded audio data.

This function is used to get audio PCM data of input media content via registered callback.
An application can specify the output PCM format by Media Format API.

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]playerThe handle to the media player
[in]formatThe media format handle about required audio PCM specification. This format has to include PCM MIME type, audio channel and sampling rate. If the format is NULL, the original PCM format or platform default PCM format will be applied.

       media_format_unref(a_format);
       ...

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.

void *  user_data 
)

Sets the seek position for playback, asynchronously.

Since :
2.3
Remarks:
This function will trigger the seeking operation on player instance like in the case of player_set_play_position_nsec(). Normally application needs to wait for player_seek_completed_cb() before calling setting position function again. Otherwise it will return PLAYER_ERROR_SEEK_FAILED.
Calling player_pause() or player_start() before player_seek_completed_cb() is invoked will cause PLAYER_ERROR_INVALID_OPERATION to be returned.

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]playerThe handle to the media player
[in]uriThe 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_NONESuccessful
PLAYER_ERROR_INVALID_PARAMETERInvalid parameter
PLAYER_ERROR_INVALID_OPERATIONInvalid operation
PLAYER_ERROR_INVALID_STATEInvalid player state
PLAYER_ERROR_PERMISSION_DENIEDPermission 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
Remarks:
This function requires the ratio value of the each coordinate and size based on the video resolution size to consider the dynamic resolution video content.
This function have to be called after calling player_set_display() and the ROI area is valid only in PLAYER_DISPLAY_TYPE_OVERLAY.
Parameters:
[in]playerThe handle to the media player
[in]x_scaleX coordinate ratio value of the video source area based on the video width size
Valid range is 0.0~1.0.
[in]y_scaleY coordinate ratio value of the video source area based on the video height size
Valid range is 0.0~1.0.
[in]w_scaleWidth 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_scaleHeight ratio value of the video source area based on the video height size
Valid range is from greater than 0.0 to 1.0.

int player_set_volume ( player_h  player,
float  left,
float  right 
)

Sets the player's volume.

Setting this volume adjusts the player's instance volume, not the system volume. The valid range is from 0 to 1.0, inclusive (1.0 = 100%). Default value is 1.0. To change system volume, use the Sound Manager API. Finally, it does not support to set other value into each channel currently.

Since :
2.3
Parameters:
[in]playerThe handle to the media player
[in]leftThe left volume scalar
[in]rightThe right volume scalar
Returns:
0 on success, otherwise a negative error value

int player_start ( player_h  player)

Starts or resumes playback.

Plays current media content, or resumes playback if the player is paused or buffering during HTTP streaming play.

Since :
2.3
Remarks:
Even if you don't set visible to true by calling player_set_display_visible(), the video will be shown on PLAYER_STATE_PLAYING state.
Since 3.0:
Sound can be mixed with other sounds, if you don't control the stream focus in sound-manager module.
You can refer to Sound Manager.
Since 5.0:
In case of HTTP streaming playback, the player could be internally paused for buffering. If the application calls this function during the buffering, the playback will be resumed by force and the buffering message posting by player_buffering_cb() will be stopped.
