enum AVPlayPlayerState {
  "NONE",
  "IDLE",
  "READY",
  "PLAYING",
  "PAUSED"
};

Since : 2.3

The following values are supported

  • NONE : Player is not created
  • IDLE : Player is created but not prepared
  • READY : Player is ready to play media
  • PLAYING : Player is playing media
  • PAUSED : Player is paused

1.2. AVPlayDisplayMode

Specifies display modes.

enum AVPlayDisplayMode { 
  "PLAYER_DISPLAY_MODE_LETTER_BOX", 
  "PLAYER_DISPLAY_MODE_FULL_SCREEN",
  "PLAYER_DISPLAY_MODE_AUTO_ASPECT_RATIO" 
};

Since : 2.3

The following values are supported

  • PLAYER_DISPLAY_MODE_LETTER_BOX : Letterbox mode
  • PLAYER_DISPLAY_MODE_FULL_SCREEN : Full-screen mode
  • PLAYER_DISPLAY_MODE_AUTO_ASPECT_RATIO : Screen mode based on video dar/par info

1.3. AVPlayBufferOption

Specifies buffering scenarios.

enum AVPlayBufferOption { 
  "PLAYER_BUFFER_FOR_PLAY", 
  "PLAYER_BUFFER_FOR_RESUME" 
};

Since : 2.3

The following values are supported

  • PLAYER_BUFFER_FOR_PLAY : Initial buffering scenario
  • PLAYER_BUFFER_FOR_RESUME : Re-buffering which might be occured after initial buffering during the playback. The onbufferingcomplete event would be triggered when the PLAYER_BUFFER_FOR_PLAY amount of data is buffered. The actual buffering completion time may vary depending on the contents format, bitrate, network speed and so on.

1.4. AVPlayBufferSizeUnit

This enumeration defines the Buffering param's Unit defined by the player.

enum AVPlayBufferSizeUnit {
  "PLAYER_BUFFER_SIZE_IN_BYTE", 
  "PLAYER_BUFFER_SIZE_IN_SECOND" 
};

Since : 2.3

The following values are supported

  • PLAYER_BUFFER_SIZE_IN_BYTE
  • PLAYER_BUFFER_SIZE_IN_SECOND : Buffer size in seconds

Remark :

"PLAYER_BUFFER_SIZE_IN_BYTE" property has been deprecated from Tizen version 5.0

1.5. AVPlayStreamingPropertyType

Specifies parameters for various streaming protocols, such as HTTP, MMS, and adaptive streaming (Smooth Streaming, HLS, and MPEG-DASH).

enum AVPlayStreamingPropertyType { 
  "COOKIE", 
  "USER_AGENT", 
  "PREBUFFER_MODE", 
  "ADAPTIVE_INFO",  
  "SET_MODE_4K",
  "PROPERTY_HD_AUDIO", 
  "LISTEN_SPARSE_TRACK", 
  "IS_LIVE", 
  "AVAILABLE_BITRATE", 
  "GET_LIVE_DURATION", 
  "CURRENT_BANDWIDTH", 
  "WIDEVINE"
};

Since : 2.3

The following values are supported

  • COOKIE : HTTP request cookie used to establish the session with the HTTP server. (for setStreamingProperty)
  • USER_AGENT : HTTP user agent, used in the HTTP request header. (for setStreamingProperty)
  • PREBUFFER_MODE : Property to initiate prebuffering mode. The second parameter indicates start-time for prebuffered content, in milliseconds. (for setStreamingProperty)
  • ADAPTIVE_INFO : Sets a custom streaming URL with various streaming parameters, such as "BITRATES", "STARTBITRATE", or "SKIPBITRATE" (for setStreamingProperty)
    String containing custom attributes for adaptive streaming playback.
    • "STARTBITRATE=" Valid values are "LOWEST", "HIGHEST", and "AVERAGE". You can also define a specific bandwidth for the start of playback.
    • "FIXED_MAX_RESOLUTION=max_widthXmax_height". Only if the given media URI such as mpd in MPEG-DASH or m3u8 in HLS through open() method doesn't describe entire required video resolutions in case of 4K / 8K adaptive streaming, application should use this attribute to complete the resolution information for the player. If the metadata file (mpd in MPEG-DASH or m3u8 in HLS) doesn’t describe the video resolutions of its contents and the max resolution of the adaptive streaming content is 3000x2000, it can be set as below.
      webapis.avplay.setStreamingProperty("ADAPTIVE_INFO", "FIXED_MAX_RESOLUTION=3000x2000");

      It might not be able to stream contents which don't have any issue when the resolution value is wrongly set and the API is unnecessarily used. So, applications should wisely use this option only when they know the exact max resolution value in case that the metadata doesn't contain the whole resolution information. It’s recommended to set the value only when 4K / 8K contents are played.
    • "BITRATES=" Use '~' to define a bandwidth range (5000 ~ 20000). You can also define a specific bandwidth for playback.
    • "SKIPBITRATE=" Defines the bandwidth to use after a skip operation.
    • "STARTFRAGMENT=" For live content playback, defines the start fragment number.
  • LISTEN_SPARSE_TRACK : For the Smooth Streaming case, configures the player to listen for a "Sparse name" configured through "propertyParam". The sparse track name is a string. (for setStreamingProperty)
  • IS_LIVE : Whether the stream is LIVE or VOD. Applicable to all streaming types. (for getStreamingProperty)
  • AVAILABLE_BITRATE : String listing the available bit-rates for the currently-playing stream. (for getStreamingProperty)
  • GET_LIVE_DURATION : String describing the duration of live content. (for getStreamingProperty)
  • CURRENT_BANDWIDTH : String describing the current streaming bandwidth. (for getStreamingProperty)
  • SET_VR360_MODE : Forces the player to use the VR360 mode. Its parameter can be the string "TRUE" or "FALSE". (for setStreamingProperty)

Remark :

"GET_LIVE_DURATION" is available since Tizen version 2.4.
"WIDEVINE" property has been deprecated from Tizen version 4.0.
"PROPERTY_HD_AUDIO" property has been deprecated from Tizen version 2.4.
"SET_VR360_MODE" property has been deprecated from Tizen version 5.0.
"SET_MODE_4K" property has been deprecated from Tizen version 5.0.

  "widevine_license_data", 
  "widevine_app_session", 
  "widevine_data_type" 
};

Since : 2.3

The following values are supported

  • SetProperties : Sets DRM instance properties and initialize the DRM instance for PlayReady, Verimatrix, and Widevine CDM.
  • InstallLicense : Base64-encoded license data for PlayReady. An application shall retrieve license data using challenge data received in ondrmevent() callback.

Methods

open
Instantiates the player object with a content URL as the input parameter.

void open(DOMString url);

Product : TV, AV_BD

Parameters:

  • url: Content URL for playback. It can be an absolute local path or a remote URL from a network-based stream server.

Constraint

  • Can be called in the following states: "NONE", "IDLE"

    • with error type InvalidStateError, if it is called in an invalid state.

    • with error type UnknownError, for any other error.

Code example:


try {
	webapis.avplay.open(url);
	}
	catch (e) 
	{
	console.log(e);
	}
close

try {
	webapis.avplay.close();
	} 
	catch (e) 
	{
	console.log(e);
	}
prepare
Prepares the media player for playback synchronously. The player must already be created with a valid URI.

	} 
	catch (e) 
	{
	console.log(e);
	}
prepareAsync
Prepares the media player for playback asynchronously. This method is preferred over prepare because it returns immediately and does not block the application thread during preparation.
When preparation is successful, the success callback is returned and the player is in READY state. If preparation fails, the error callback returns the error value.
When prepareAsync is used with "PREBUFFER_MODE", successCallback is invoked when prebuffering is complete, instead of when preparation is complete.

void prepareAsync(optional SuccessCallback? successCallback, optional ErrorCallback? errorCallback);

Product : TV, AV_BD

	} 
	catch (e) 
	{
	console.log(e);
	}

Remark :

Adaptive streaming using TS container (for e.g. HLS) with audio sample rate changing across variants may cause audio loss.
seekTo
Skips playback to a specific timestamp.
For HTTP streaming, this method is successful even when the specified timestamp is invalid. The internal player automatically resets an out-of-range value to an in-range one.

void seekTo(long milliseconds, optional SuccessCallback? successCallback, optional ErrorCallback? errorCallback);

Product : TV, AV_BD

Parameters:

  • milliseconds: Timestamp to skip to
  • successCallback: Callback method to invoke when the call is successful
  • errorCallback: Callback method to invoke when an error occurs

Constraint

  • Can be called in the following states: "IDLE","READY", "PLAYING" (buffered data is flushed and buffering starts over), "PAUSED".
    During this async operation, the other API would not be allowed. So, the application needs to wait for one of both callbacks( SuccessCallback, errorCallback) before any other API call.
    For LIVE stream case, seek position must be within DVR range. DVR range could be retrieved using GET_LIVE_DURATION property in getStreamingProperty API.

Exceptions:

  • WebAPIException

    • with error type TypeMismatchError, if an input parameter is not compatible with its expected type.

    • with error type NotSupportedError, if this feature is not supported.

    • with error type InvalidValuesError, if any input parameter contains an invalid value.

    • with error type UnknownError, for any other error.

Code example:


try {
	webapis.avplay.seekTo(10000,successCallback, errorCallback);
	}
	catch (e)
	{
		console.log(e);
	}
// for live cases, get the live duration as :
var StartTime = webapis.avplay.getStreamingProperty("GET_LIVE_DURATION").split('|')[0];
var EndTime = webapis.avplay.getStreamingProperty("GET_LIVE_DURATION").split('|')[1];
// seekpoint must be between StartTime and Endtime.
stop
Stops the player. Call this function after the video finishes playing.

void stop();

Product : TV, AV_BD

Constraint

  • Can be called in the following states: "NONE", "IDLE", "READY", "PLAYING", "PAUSED"

Exceptions:

  • WebAPIException

	} 
	catch (e) 
	{
	console.log(e);
	}
jumpForward
Skips playback forward by a specific amount of time. The player state is unchanged.
Passing the optional callbacks is recommended. For best performance, ensure that the previous call to this API was successful.
For HTTP streaming, this method is successful even when the resulting timestamp is invalid. The internal player automatically resets an out-of-range value to an in-range one.

  }
});
restore
During multitasking, restores the player state when the application is resumed. For live streaming or DRM-encrypted content playback, you must check whether the streaming URL has changed or the DRM session or license has expired, and specify the new URL and DRM information as needed.

void restore(DOMString URL, optional unsigned long? resumeTime, optional boolean? bPrepare);

Product : TV, AV_BD

Parameters

  • URL: updated URL after suspend. If null, the stored URL is used.
    For live streaming or DRM-encrypted content playback, in case the URL has changed or the DRM license or session has expired, checking for and passing the newest URL is recommended.
  • resumeTime: (milliseconds) Optional. Position from which to resume playback. If 0, the stored position is used.
    For live streaming, this parameter is not meaningful. Do not pass 0 for this parameter.
    For DRM-encrypted content playback, if the DRM session has expired, to recreate the playback pipeline, pass 0 for this parameter.
  • bPrepare: Optional boolean. false (default): Player sets the resume behavior automatically. true: Player does not resume automatically. The application must invoke the prepare and play methods.
    For live streaming, this parameter is not meaningful. Do not pass true for this parameter.
    For DRM-encrypted content playback: if the DRM session has expired, pass true for this parameter.

Constraint

  • Can be called in the following states: "NONE", "PLAYING", "PAUSED"

  {
    // Something you want to do when application is resumed
    console.log("lifecycle [resume]");
    webapis.avplay.restore(url, 0, false);
  }
});
restoreAsync
During multitasking, restores the player state when the application is resumed.restoreAsync is an asynchronous interface.
Other API, restore is a synchronous interface which blocks the application thread. This method is preferred over restore because it returns immediately and does not block the application thread during its restoration.
When player is restored successful, the success callback is returned and player resumed the playback from the restored playback position, state, properties etc. If restoration fails, the error callback returns the error value.
Application is required to make further calls to avplay on its success or failure callback happens.
For live streaming or DRM-encrypted content playback, you must check whether the streaming URL has changed or the DRM session or license has expired, and specify the new URL and DRM information as needed.

void restoreAsync(DOMString URL, optional unsigned long? resumeTime, optioanl boolean? bPrepare, optional SuccessCallback? successCallback, optional ErrorCallback? errorCallback);

Product : TV, AV_BD

Parameters

  • URL: updated URL after suspend. If null, the stored URL is used.
    For live streaming or DRM-encrypted content playback, in case the URL has changed or the DRM license or session has expired, checking for and passing the newest URL is recommended.
  • resumeTime: (milliseconds) Optional. Position from which to resume playback. If 0, the stored position is used. For live streaming, this parameter is not meaningful. Do not pass 0 for this parameter. For DRM-encrypted content playback, if the DRM session has expired, to recreate the playback pipeline, pass 0 for this parameter.
  • bPrepare: Optional boolean. false (default): Player sets the resume behavior automatically. true: Player does not resume automatically. The application must invoke the prepare and play methods.
    For live streaming, this parameter is not meaningful. Do not pass true for this parameter.
    For DRM-encrypted content playback: if the DRM session has expired, pass true for this parameter.
  • successCallback: Callback method to invoke when the call is successful
  • errorCallback: Callback method to invoke when an error occurs
