Remove constructor detect instanceof video

[a-wing]

I am trying to fake a video object to use.

Because look like Browser play plugin don't use <video/>

For example: https://github.com/Kagami/mpv.js

[weizhenye]

ASS.js requires <video> to bind events, control playback, and so on. Faking a video object seems not easy.
#11 wants to use ASS.js without <video> too, I don't find out a general way to support those situation yet.

I am simulating an event on

ass.js need property and event

/**                                           
* HTMLVideoElement                         
*                                                                                             
* HTMLElement -> HTMLMediaElement -> HTMLVideoElement
*                             
* https://developer.mozilla.org/en-US/docs/Web/API/HTMLVideoElement                           
* HTMLVideoElement.videoHeight :only      
* HTMLVideoElement.videoWidth :only
*                                              
* HTMLMediaElement.paused :only                                                               
* HTMLMediaElement.currentTime  
*                                                                                             
* https://developer.mozilla.org/en-US/docs/Web/API/Element
* Element.clientWidth                                                                         
* Element.clientHeight                      
*                         
*                     
* Events -> Media_events                       
* https://developer.mozilla.org/en-US/docs/Web/Guide/Events/Media_events
* play, pause, seeking                                                                        
*/

But HTMLVideoElement.videoHeight And HTMLVideoElement.videoWidth only read

So can't use HTMLMediaElement

About event. My current solution is:

let video = document.createElement('div');
let event = document.createEvent('Event');
event.initEvent('pause', true, true);

video.dispatchEvent(event);
