The Tizen player is used in Media Station X version 0.1.128 or higher for all Samsung TVs (2016+ models). In previous versions, the HTML5 player is used. The Tizen player works similar to the HTML5 player, but supports more video formats (e.g. 4k/8k formats) and can be configured via the Extended Properties of a content item to setup display, buffer, and/or stream settings. Additionally, you can interact with it using the player:commit actions to get the current stream information and/or to select a specific audio/text track. Please see #Runtime Usage for more information. Some extended properties are dynamic and can also be set via an action at runtime.

Most of the extended properties are directly mapped to a corresponding Tizen (i.e. AVPlay API) function. For more information, please visit following links.

Note: All properties are reset if a new video/audio is played. Please also note that you can still use the HTML5 player with a plugin (see Video/Audio Plugin#Examples). It should be mentioned here that setting the speed only works with the HTML5 player, because the AVPlay API does not support the required speed values.

Runtime Usage[edit]

It is possible to request data from the Tizen player (e.g. from an interaction plugin) and/or to set some extended properties via an action at runtime.

Actions[edit]

Action syntax for Tizen player
Syntax & Example Data Tizen Function Since Version Description

player:commit:message:{PROPERTY}:{VALUE}

player:commit:message:tizen:track:audio:1
player:commit:message:tizen:track:text:1

 n/a n/a 0.1.128 Sets up an extended property during runtime.

Note: Only the dynamic properties can be set at runtime.

Please see #Syntax for more information.

player:commit 
{
   "key": "{PROPERTY}",
   "value": "{VALUE}",
   "action": "{ACTION}",
   "data": null
}
n/a 0.1.128 Sets up an extended property during runtime and optionally executes an action on completion.

Note: Only the dynamic properties can be set at runtime.

Please see #Syntax for more information.

Example[edit]

This example uses an interaciton plugin to interact with the Tizen player. You can use it as is or integrate it into your existing interaction plugin. Please have a look at this implementation script: https://msx.benzac.de/interaction/js/tizen.js.
