Demo

[edit]

Tag 

<ogg>uploaded filename.ogg</ogg>

or 

<ogg>uploaded filename.ogg|download|width|height|video|duration</ogg>

The "download" parameter adds an icon with link to download the ogg
The "width" and "height parameters are the size of the applet
The video parameter should be either true or false. False if you are just playing audio.
The "duration" parameter is so the file will be seekable. 

<ogg>Juggling_jack01.ogg|download|320|240|true|14</ogg>
