Cast your video element to the big screen with ease!

The lightweight CastableVideoElement class extends the native HTMLVideoElement API
and adds casting functionality to any video element.
The API aims to be equivalent to the
Remote Playback API
with a few extra element attributes specific to casting.

It was primarily built for use in Media Chrome
but it works great with any custom video controls as you can see in the example.

Remote Playback API

$3

- video.remote.prompt(): open the browser casting menu.
- video.remote.watchAvailability(callback): watch if remote devices are available.
- video.remote.cancelWatchAvailability(callback): cancel watching for remote devices.

$3

- video.remote.state: the current cast state.
- disconnected: Cast devices are available, but a cast session is not established.
- connecting: Cast session is being established.
- connected: Cast session is established.
- castOptions [readonly]: the cast options passed to the cast session.
- receiverApplicationId: defaults to Chromecast default receiver.
- autoJoinPolicy ('ORIGIN_SCOPED')
- androidReceiverCompatible (false): if true enables Cast Connect.
- language ('en-US')
- resumeSavedSession (true)

$3

- connecting: fires when a cast session is being established.
- connect: fires when starting casting.
- disconnect: fires when stopping casting.

e.g. video.remote.addEventListener('connect', () => {})

$3

Each attribute has a corresponding element property. e.g. video.castSrc or video.castStreamType.

- cast-src: if Chromecast requires a different source than the one loaded.
For example this would be needed if video src is a blob when using MSE.
- cast-stream-type: add for live streams.
- cast-content-type: required if Chromecast can't derive the content type from the source.
- cast-receiver: the Chromecast receiver app id. Defaults to CC1AD845.

$3

When your media element is using Media Source Extension (MSE) element has a src like src="blob://.... If you are using Hls.js or Dash.js you may have noticed this. Because of the blob://.., castable-video has no way to know what the source is, so you must set the cast-src= attribute to the full URL of the video source.
