941 * already transparent. Defaults to `#ffffff`.
942 * - `height` (integer): The height of the embedded media. Accepts any
943 * numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
944 * and it is recommended that you use this default.
945 * - `loop` (boolean): Do you want the media to loop when its done?
946 * Defaults to `false`.
947 * - `mediaplayer` (string): The location of the included
948 * `mediaplayer.swf` file. This allows for the playback of Flash Video
949 * (`.flv`) files, and is the default handler for non-Odeo MP3's.
950 * Defaults to blank.
951 * - `video` (string): This is an image that should be used as a
952 * placeholder for video files before they're loaded (QuickTime-only).
953 * Can be any relative or absolute URL. Defaults to blank.
954 * - `width` (integer): The width of the embedded media. Accepts any
955 * numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
956 * and it is recommended that you use this default.
957 * - `widescreen` (boolean): Is the enclosure widescreen or standard?
958 * This applies only to video enclosures, and will automatically resize
959 * the content appropriately. Defaults to `false`, implying 4:3 mode.
960 *
961 * Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
962 * will default to 480x360 video resolution. Widescreen (16:9) mode with
963 * `width` and `height` set to `auto` will default to 480x270 video resolution.
964 *
965 * @todo If the dimensions for media:content are defined, use them when width/height are set to 'auto'.
966 * @param array|string $options Comma-separated key:value list, or array
967 * @param bool $native Use `<embed>`
968 * @return string HTML string to output
