= Metaviewer plugin = 

This plugin prints metadata and keyframe positions enclosed in videos in a textbox on screen, which is useful for debugging purposes. It works for MP3, FLV and MP4.

This plugin is compatible with version 4.1 of the player. Its positioning flashvars work since version 4.4.

== Example == 

Here is an example of the Metaviewer plugin in action. Play the video to see the data:

[[JWPlayer(400,250,file=/player/testing/files/bunny.flv&plugins=metaviewer)]]

{{{
file=/player/testing/files/bunny.flv&plugins=metaviewer
}}}

 
== Configuration == 

The plugin is loaded with the flashvar ''plugins=metaviewer''. This will automatically load the latest version of the plugin straight off our servers. It offers a string of flashvars for tweaking the plugin:

 * '''metaviewer.position''' (''over''): position of the plugin. Can be ''over'', ''left'', ''right'', ''top'' or ''bottom''.
 * '''metaviewer.size''' (''100''): when the plugin is set to display ''left'' or ''right'', this defines the width of the area the plugin uses. When the plugin is positioned ''top'' or ''bottom'', this defines the height of the area the plugin uses.
