Hacker Guide/Modules source tree

This page lists the content of the Modules directory in the source tree of VLC, aimed at giving new beginners an overview of the code.

 Why Does This Page Exist?
 Well, simply because VLC has evolved with not so much accumulation in mind, 
 and when a new coder looks at the code, s/he is   terrified by the abundance of directories and plugins (271 as of writing!). 
 Please remove this paragraph when done.

The directories are listed in alphabetical order, with an overview of their contents on the right. Any first level subdirectories are shown as well.

Note: This table is by no means exhaustive. Note that only plugins with their own subdirectories are listed; plugins inside the parent directories are not emphasized unless they are too important. A comprehensive list of the plugins VLC makes use of can be found here.
