本网页列出VLC源代码树中 Modules目录中各子项目，目的是为了给新的VLC开发者对code有个总体的把握。各子目录按照字母顺序被列出，在列表右侧是对各目录功能的详细说明，每个目录下面的第一个子目录也被列出，为了更详细的VLC modules说明，请看这里https://wiki.videolan.org/Documentation:Modules/
注意：下面这张”目录“表示不完整的，注意表中仅仅列出了与子目录联系紧密的插件。虽然某个插件（子模块）也处于某个目录下面但不会被列出，除非它非常重要。如果想全面、完整的了解VLC所用到plugins，请查阅source code中modules/MODULES_LIST 这个文件即可。
