Kaltura Player JS Platform - Cloud TV and OVP Media Players Based on the PlayKit JS Player

Build Status code style: prettier

The Kaltura Player utilizes a highly modular approach for creating a powerful media player. Each functionality of the player is isolated into separate packages, which are designed to deliver a specific set of abilities. This approach enables extensibility, simplicity and easy maintenance.

The Kaltura Player integrates:

The Kaltura Player exposes two different players: the Kaltura OVP Player and Kaltura Cloud TV Player. Each player integrates its related packages, as you can see in the following table:

  PlayKit JS PlayKit JS Providers PlayKit JS UI PlayKit JS DASH PlayKit JS HLS PlayKit JS Youbora PlayKit JS OTT Analytics PlayKit JS KAVA  
OVP Player V OVP V V V V   V  
Cloud TV Player V OTT V V V V V V (*)  

* Needs to be configured.

The Kaltura Player is written in ECMAScript6, statically analysed using Flow and transpiled in ECMAScript5 using Babel.
