* Name: Handle Video

* Author: velocity37 <velocity37@gmail.com>
|

* Modified By: Shish <webmaster@shishnet.org>, jgen <jeffgenovy@gmail.com>

|
|
* Description: Handle FLV, MP4, OGV and WEBM video files.
|
|
* Documentation:
|
|
* Based heavily on "Handle MP3" by Shish.<br><br>
|
|
* FLV: Flash player<br>
|
|
* MP4: HTML5 with Flash fallback<br>
|
|
* OGV, WEBM: HTML5<br>
|
|
* 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.<br><br>
|
|
* Made possible by:<br>
|
|
* <a href='http://getid3.sourceforge.net/'>getID3()</a> - Gets media information with PHP (no bulky FFMPEG API required).<br>
|
|
* <a href='http://jarisflvplayer.org/'>Jaris FLV Player</a> - GPLv3 flash multimedia player.
