Support IE about mat-video

[nkoehler]

Firstly, thank you for using mat-video, and taking the time to submit an issue request.

When I started this project, I had plans to support IE because I understand some users continue to use it. As I was developing mat-video 1.0, I realized several features that worked wonderfully in modern browsers, always required special attention for Internet Explorer.

During the time I spent creating mat-video, I noticed that I was spending way too much time writing specific IE code that would work for IE. New features took twice as long, because extra code always had to be written for IE. Before the first release of mat-video, I decided that the time investment was not worth the effort to support an old browser.

The more I researched IE support, the more I learned how difficult it would be to continue to support it. IE is a very outdated browser, which does not conform to modern standards at all. It would require tons of additional code and hacks just to keep it up to date with the other browsers.

Angular without polyfills only supports the evergreen browsers, and Microsoft has already ended mainstream support for IE11. In fact, GitHub doesn't even support IE anymore.

Unfortunately, I will not be able to accommodate this request. There is no IE support for mat-video.
Hopefully you understand, thanks.
