Upgrading to Angular 9

[Eraldo]

I am trying to upgrade to Angular 8 but received the following warnings:

Package "ngx-embed-video" has an incompatible peer dependency to "@angular/core" (requires "^6.0.0" (extended), would install "9.0.1").
Package "ngx-embed-video" has an incompatible peer dependency to "@angular/common" (requires "^6.0.0" (extended), would install "9.0.1").

related to issue #30.

Compile trace states: "please contact the library authors"

ERROR in node_modules/ngx-embed-video/dist/index.d.ts:4:23 - error NG6005: 
EmbedVideo.forRoot returns a ModuleWithProviders type without a generic type argument. 
Please add a generic type argument to the ModuleWithProviders type. 
If this occurrence is in library code you don't control, 
  please contact the library authors.

For us, it would not allow our production builds to run. I'm not sure why. But we have just included the code as a local service, and it works. Here is the local service code, in case anyone is interested:
`/**

• This code originally from https://www.npmjs.com/package/ngx-embed-video.
• The way it was packaged, however, caused run problems on production builds, possibly to do with not being compatible with Ivy
• in the most recent versions of angular.
• The code was cleaned up to work with stricter tslint settings, consistent identifier naming,
• and to add alts to images for WCAG compliance.
