* Modified By: Shish , jgen , im-mi * License: GPLv2 * Description: Handle FLV, MP4, OGV and WEBM video files. * Documentation: * Based heavily on "Handle MP3" by Shish.

* FLV: Flash player
* MP4: HTML5 with Flash fallback
* OGV, WEBM: HTML5
* MP4's flash fallback is forced with a bit of Javascript as some browsers won't fallback if they can't play H.264. * In the future, it may be necessary to change the user agent checks to reflect the current state of H.264 support.
