A custom element for extending the native media elements (`<audio>` or `<video>`).


## Usage

```js
import { CustomVideoElement } from 'custom-media-element';

class MyCustomVideoElement extends CustomVideoElement {
  constructor() {
    super();
  }

  // Override the play method.
  play() {
    return super.play()
  }

  // Override the src getter & setter.
  get src() {
    return super.src;
  }

  set src(src) {
    super.src = src;
  }
}

if (globalThis.customElements && !globalThis.customElements.get('my-custom-video')) {
  globalThis.customElements.define('my-custom-video', MyCustomVideoElement);
}

export default MyCustomVideoElement;
```

```html
<my-custom-video
  src="https://stream.mux.com/A3VXy02VoUinw01pwyomEO3bHnG4P32xzV7u1j1FSzjNg/low.mp4"
></my-custom-video>
```

export class CustomAudioElement extends HTMLAudioElement implements HTMLAudioElement {
  static readonly observedAttributes: string[];
  static Events: string[];
  static template: HTMLTemplateElement;
  readonly nativeEl: HTMLAudioElement;
  attributeChangedCallback(attrName: string, oldValue?: string | null, newValue?: string | null): void;
  connectedCallback(): void;

}

export class CustomVideoElement extends HTMLVideoElement implements HTMLVideoElement {
  static readonly observedAttributes: string[];
  static Events: string[];
  static template: HTMLTemplateElement;

}

type CustomMediaElementConstructor<T> = {
  readonly observedAttributes: string[];
  Events: string[];
  template: HTMLTemplateElement;
  new(): T
};

export function CustomMediaMixin(superclass: any, options: { tag: 'video', is?: string }):
  CustomMediaElementConstructor<CustomVideoElement>;

export function CustomMediaMixin(superclass: any, options: { tag: 'audio', is?: string }):
  CustomMediaElementConstructor<CustomAudioElement>;
