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.

• AVPlay API: https://developer.samsung.com/smarttv/develop/api-references/samsung-product-api-references/avplay-api.html
• Using AVPlay: https://developer.samsung.com/smarttv/develop/guides/multimedia/media-playback/using-avplay.html

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.
