--- Need to write what this link is and place it , in the right location ---> VIDEO.JS - HTML5 Video Player
Video.js is a web video player built from the ground up for an HTML5 world. It supports HTML5 and Flash video, as well as YouTube and Vimeo (through plugins). It supports video playback on desktops and mobile devices. This project was started mid 2010, and the player is now used on over 200,000 websites
Video.JS is compatible with many Browsers and Devices, thus makes it available on many platforms (including ones without java script). This is achieved through the use of embedded code. The java script library fixes browser & device bugs, and makes sure your video is even more compatible across different browser versions. The pure HTML5/CSS skin ensures a consistent look between HTML5 browsers, and easy custom skinning if you want to give it a specific look, or brand it with your own colors.
The Advantages :
- Free & Open Source
- Lightweight. NO IMAGES USED
- 100% skinnable using CSS
- Library independent
- Easy to use
- Easy to understand & extend
- Consistent look between browsers
- Full Screen & Full Window Modes
- Volume Control
- Forced fallback to Flash (even when there is an unsupported source)

- Technical direction
- Project governance and process (including this policy)
- Contribution policy
- GitHub repository hosting
- Conduct guidelines
- Maintaining the list of additional collaborators
Collaborators
Modifications of the contents of the videojs/video.js repository are made on a collaborative basis.

###Variablity The project is divide by 3 modules (Core, Plugins, Skins). The core library handles the actual video player capabilities, reading video from many type of sources , and displaying it on HTML5 enviroment. The core module is a rigid module, any change or feature addition to the core requires an authorization of the TC Committee. Plugin and skins , are ment to allow specific customization, for many users. this feature makes Video.JS accessible. Plugin examples - subtitles, recording,playlist playing etc. These module are more easy to change and commit the changes.
###**Core library ** The Javascript core library in video.js is divided in seven principal sections:
- Control-Bar -- All the types of controls (i.e. Audio, Progress, Volume)
- Menu -- All the menu components (i.e Buttons, Items)
- Popup -- The Popup component is used to build pop up controls
- Slider -- The base functionality for sliders like the volume bar and seek bar
- Tech -- Module for media (HTML5 Video, Flash) controllers
- Tracks -- Setup the common parts of an audio, video, or text track
- Utils -- Various utilities
