 * A Custom `MediaError` class which mimics the standard HTML5 `MediaError` class.

 * @param {number|string|Object|MediaError} value

 *        - number: should be a standard error code
 *        - string: an error message (the code will be 0)
 *        - Object: arbitrary properties

 *        - `MediaError` (video.js): will return itself if it's already a
 *          video.js `MediaError` object.
