 | |

 | |
| 	 *    the appropriate handler installed or when a file type is
 | |
| 	 *    unsupported. Can be any text or HTML. Defaults to blank.
 | |
| 	 * - `altclass` (string): If a file type is unsupported, the end-user will
 | |
| 	 *    see the alt text (above) linked directly to the content. That link
 | |
| 	 *    will have this value as its class name. Defaults to blank.
 | |
| 	 * - `audio` (string): This is an image that should be used as a
 | |
| 	 *    placeholder for audio files before they're loaded (QuickTime-only).
 | |
| 	 *    Can be any relative or absolute URL. Defaults to blank.
 | |
| 	 * - `bgcolor` (string): The background color for the media, if not
 | |
| 	 *    already transparent. Defaults to `#ffffff`.
 | |
| 	 * - `height` (integer): The height of the embedded media. Accepts any
 | |
| 	 *    numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
 | |
| 	 *    and it is recommended that you use this default.
 | |
| 	 * - `loop` (boolean): Do you want the media to loop when it's done?
 | |
| 	 *    Defaults to `false`.
 | |
| 	 * - `mediaplayer` (string): The location of the included
 | |
| 	 *    `mediaplayer.swf` file. This allows for the playback of Flash Video
 | |
| 	 *    (`.flv`) files, and is the default handler for non-Odeo MP3's.
 | |
| 	 *    Defaults to blank.
 | |
| 	 * - `video` (string): This is an image that should be used as a
 | |
| 	 *    placeholder for video files before they're loaded (QuickTime-only).
 | |
| 	 *    Can be any relative or absolute URL. Defaults to blank.
 | |
| 	 * - `width` (integer): The width of the embedded media. Accepts any
 | |
| 	 *    numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
 | |
| 	 *    and it is recommended that you use this default.
 | |
| 	 * - `widescreen` (boolean): Is the enclosure widescreen or standard?
 | |
| 	 *    This applies only to video enclosures, and will automatically resize
 | |
| 	 *    the content appropriately.  Defaults to `false`, implying 4:3 mode.
 | |

 | |

 | |
| 	 * `width` and `height` set to `auto` will default to 480x270 video resolution.
