## Description
The `psammead-media-player` component exports two versions of our media player: an AMP version, and an Canonical version.
At its core, this component returns an `iframe` that is designed to frame a media asset.
The AMP variant will render an `amp-iframe` with a nested `amp-img` to use as a placeholder.
The Canonical variant will render a placeholder, that when clicked will load the `iframe` into view.
## When to use this component
This component to be used at any point on the page, specifically when a media player is needed.
## Installation
`npm install @bbc/psammead-media-player`

The `src` prop is required, as it tells the component what page it needs to embed.
The `placeholderSrcset` prop is not required, as it allows image responsiveness and optimization depending on the size of the screen.
The `title` prop is required for accessibility of the embedded iframe.
The `portrait` prop is not required, and defaults to `false`. This is to support portrait video content in the future.
The `showPlaceholder` boolean prop is also not required, and defaults to `true`.
Assuming `showPlaceholder` is `true`, the `placeholderSrc` will be what image to display as the placeholder.
The `noJsClassName` is an optional prop that defaults to `null` and is used to add styling support to certain elements when javascript is disabled in the browser.
The `noJsMessage` is a required prop used display a fallback text when javascript is disabled in the browser.
The `mediaInfo` prop is required, and has the following properties.
#### mediaInfo

| `title` | string | Yes | - | `'A vertical video pretending to be a cat title'` |
| `datetime` | string | No | - | `'PT11S'` |
| `duration` | string | No | - | `'0:11'` |
| `durationSpoken` | string | No | - | `'11 seconds'` |
| `type` | string | No | `"video"` | `'audio'` |
| `guidanceMessage` | string | No | - | `'May contain strong language,sexual or violent content that may offend'` |
#### Events
The canonical media player accepts callback functions which it will invoke in response to events that are posted from the iframe. The following events are currently supported:
| Event | Description |
| -----------------------| ---------------------------------------------------------------------------------|
| `onMediaInitialised` | Called when the media player has loaded and is ready to begin playback |
| `onMediaPlaying` | Called when the media player has started playing |
| `onMediaPause` | Called when the user has paused playback |
| `onMediaEnded` | Called when a playlist item (including an ad or an ident) has completed playback |
| `onMediaPlaylistEnded` | Called when an entire playlist has completed playback |
| `onMediaError` | Called when the media player has encountered an error |
When using the BBC's iFrame, these callbacks are invoked with a lot of additional information on the nature of the event. Internal users should refer to the SMP documentation for more details
### AmpMediaPlayer
| Argument | Type | Required | Default | Example |
| ------------------- | ------- | -------- | ------- | -------------------------------------------------------------------------------------------------------- |
| `src` | string | Yes | - | `http://foobar.com/embeddable_endpoint` |
| `placeholderSrcset` | string | No | `null` | `'https://bbc.com/300/cat.jpg 300w, https://bbc.com/450/cat.jpg 450w, https://bbc.com/600/cat.jpg 600w'` |
| `title` | string | Yes | - | `Video player` |
| `portrait` | boolean | No | `false` | `true` |
| `placeholderSrc` | string | Yes | - | `'http://foobar.com/placeholder.png'` |
The `placeholderSrc` prop is required for AMP, as in order to have the component load an `amp-iframe` within 600px or 75% of the viewport from the top, we must have an `amp-img` placeholder. For more information on this, please refer to the [AMP docs for amp-iframe](https://amp.dev/documentation/components/amp-iframe/).

## Accessibility notes
The `title` prop is important for [accessibility](https://www.w3.org/TR/WCAG20-TECHS/H64.html). It is meant for the user and should be translated to match the user's language.
