Customizing the Player V4 Skin with skin.json

In addition to using the Backlot UI, you can make customizations to the Player V4 and the Android and iOS skin UX by modifying the key/value pairs in the JSON config file (skin.json). You can use the same skin.json file for your HTML5, Android SDK, and iOS SDK players.

To use skin.json to customize the player look and feel, do the following:

  1. Download the latest version of the skin.json config file:
  2. Host the skin.json config file on your server.
  3. Make modifications to the JSON attributes to apply look and feel changes to your player.
  4. Reference the absolute path to your skin.json file when you load your player.
Note: Customize skin.json only if you want to change configuration settings in the file. Alternatively, you can simply use the default settings. If you want to override some skin settings, you can use the skin.inline parameter when you embed Player V4 on a web page. See Page-level Parameters for Player V4 for details.

To view the API documentation for skin.json, go to The following table shows the path to the documentation for each customizable player component. See User Interface for the Player V4 Skin for a description of the player components.
