Media Plugin is a plug-in in the [[DCERouter]] that is responsible for media management in LinuxMCE. Extension plug-ins can register with it to provide control for media types that Media Plugin doesn't handle itself.

 +
== Events ==
 +
Media Plugin handles the following events:
 +
=== Media Inserted ===
 +
=== Playback Completed ===
 +
=== Playback Started ===
 +
==== Description ====
 +
When playback of a media stream starts, this event is emitted by the player. When this event is received by the Media Plugin, it updates the playback status of the corresponding stream. If the stream is a DVD, it also updates the section descriptions.

|Stream&nbsp;ID||The ID of the stream this message refers to.
 +
|-
 +
|MRL||The MRL of the stream. Not used.
 +
|-
 +
|SectionDescription||If the stream is a DVD, this parameter should contain the description for the DVD sections.
 +
Each section description is given on a separate line ended with LF (\n).<br/>
 +
The format of each line is as follows:<br/>
 +

Media Plugin handles the following events:

Media Inserted
