Tizen Player

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). 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

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.
