This plugin allows you to configure extra mime-types for support by the inline-uploader.
A new options page is added as Options … Mime-types which allows you to add/delete the extra mime-types.
By default the following extra mime-types are registered: audio/ac3, audio/MPA and video/x-flv.
With version 0.90 of the plugin you are now able to upload a file containing a long list of mime types as an easy way to register multiple mime-types. 
The file format is “mime/type extension” for example like this:
<pre><code>audio/ac3 ac3
audio/MPA mpa
video/x-flv flv
</code></pre>
