* Media players return embed HTML for a particular way of playing back audio
* or video (or another file type).
*
* In order to make the code more lightweight, this is not a plugin type
* (players cannot have their own settings, database tables, capabilities, etc).
* These classes are used only by core_media_renderer in outputrenderers.php.
* If you add a new class here (in core code) you must modify the
* get_players_raw function in that file to include it.
*
* If a Moodle installation wishes to add extra player objects they can do so
* by overriding that renderer in theme, and overriding the get_players_raw
* function. The new player class should then of course be defined within the
* custom theme or other suitable location, not in this file.
