* 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.
* Made possible by:
* getID3() - Gets media information with PHP (no bulky FFMPEG API required).
* Jaris FLV Player - GPLv3 flash multimedia player.
