Check usage (experimental)

This Mp3 extension inserts a really light Flash player which streams an uploaded (or external) MP3 file. It's based on Extension:Mp3 but uses a different flash player and has more options and is compatible with newer versions of Mediawiki.

You can download the player from flash-mp3-player.net.

Usage

<mp3 bg="00FF00" color="FF0000">702 Promo.mp3</mp3>
<mp3 bg="00FF00" color="FF0000">http://www.aiowiki.com/w/images/4/40/702_Promo.mp3</mp3>
[[file:702 Promo.mp3]] - can't use custom colors

If the bg (background) value is not given it will default to transparent, if the color value is not given it defaults to a blue color

Requirements

• player_mp3_mini.swf in your extensions/MiniMp3 directory

Install instructions

• Include in your LocalSettings.php:

require_once( "$IP/extensions/MiniMp3/MiniMp3.php");

• If you want to accept mp3 uploads, add .mp3 in the extension list:

$wgFileExtensions = array('png','gif',...,'mp3');

PHP code (copy from here!)

save the below code as MiniMp3.php and save it in your extensions/MiniMp3 directory

To DO

• fix any XSS problems
• get [[File:blah.mp3|color=00FF00]] to work, although I've been told on IRC it can't be done without changes to the core
