Annotation Plugin for Videojs

Hi,

I attached Open Video Annotation Support for "Videojs HTML5 Player Module" in Drupal 8 simple patch here.

This module supports annotations in videojs html5 player which has extensions mp4,webm,youtube & vimeo which is hard coded now. Further updates will be user friendly and also you should create "Videojs Textfield" Text field for Enable Open Video Annotation Plugin. the machine name should be "field_videojs_textfield" this can be altered in future for user friendly.

This module allows "Videojs TextField Formatter" by creating "Videojs Textfield". Similarly this module works with file/video field types(only support mp4 extension file).

CSS & JS files are found at: https://github.com/CtrHellenicStudies/OpenVideoAnnotation. Make sure to avoid jquery conflict you should use WRAPPING method for all js files and also create jquery-noconflict.js file which contains the mentioned code

var jQuery13 = jQuery;
jQuery.noConflict(true);

Other js files should be wrapped like (function($){ //js code })(jQuery); // This will avoid core jquery conflictions.
Load the js files should be in the correct order. (Refer to: videojs.libraries.yml file)

To Load the plugin Open Video Annotation you should load addannotatebutton.js file.
Pros and Cons are welcome.

Patch Updated For Settings Form in Videojs Annotation Plugin with TextField Formatter as well as File and Video Fields.

This Patch Currently Supports mp4,webm,ogg Formats.

youtube format support only when enabling "Enable Annoation checkbox in Videojs Player formatter/Videojs Player Textfield Formatter" settings. Other formats works fine.

Pros and Cons are welcome.
