PeerTube Embed API

PeerTube lets you embed videos and programmatically control their playback. This documentation covers how to interact with the PeerTube Embed API.

Playground

Any PeerTube embed URL (ie https://my-instance.example.com/videos/embed/52a10666-3a18-4e73-93da-e8d3c12c305a) can be viewed as an embedding playground which allows you to test various aspects of PeerTube embeds. Simply replace /embed with /test-embed and visit the URL in a browser. For instance, the playground URL for the above embed URL is https://my-instance.example.com/videos/test-embed/52a10666-3a18-4e73-93da-e8d3c12c305a.

Quick Start

Given an existing PeerTube embed <iframe> with API enabled (https://my-instance.example.com/videos/embed/52a10666-3a18-4e73-93da-e8d3c12c305a?api=1), one can use the PeerTube Embed API to control it by first including the library. You can include it via Yarn with:

yarn add @peertube/embed-api

Now just use the PeerTubePlayer class exported by the module:

import { PeerTubePlayer } from '@peertube/embed-api'

...

Or use the minified build from NPM CDN in your HTML file:

<script src="https://unpkg.com/@peertube/embed-api/build/player.min.js"></script>

<script>
  const PeerTubePlayer = window['PeerTubePlayer']

  ...
</script>

Then you can instantiate the player:

let player = new PeerTubePlayer(document.querySelector('iframe'))
await player.ready // wait for the player to be ready

// now you can use it!
player.play()
player.seek(32)
player.pause()

Methods

play() : Promise<void>

Starts playback, or resumes playback if it is paused.

pause() : Promise<void>

Pauses playback.

seek(positionInSeconds : number)

Seek to the given position, as specified in seconds into the video.

addEventListener(eventName : string, handler : Function)

Add a listener for a specific event. See below for the available events.

getResolutions() : Promise<PeerTubeResolution[]>

Get the available resolutions. A PeerTubeResolution looks like:

{
    "id": 3,
    "label": "720p",
    "height": "720",
    "active": true
}

active is true if the resolution is the currently selected resolution.

setResolution(resolutionId : number): Promise<void>

Change the current resolution. Pass -1 for automatic resolution (when available). Otherwise, resolutionId should be the ID of an object returned by getResolutions()

getPlaybackRates() : Promise<number[]>

Get the available playback rates, where 1 represents normal speed, 0.5 is half speed, 2 is double speed, etc.

getPlaybackRates() : Promise<number>

Get the current playback rate. See getPlaybackRates() for more information.

setPlaybackRate(rate: number) : Promise<void>

Set the current playback rate. The passed rate should be a value as returned by getPlaybackRates().

setVolume(factor: number) : Promise<void>

Set the playback volume. Value should be between 0 and 1.

getVolume(): Promise<number>

Get the playback volume. Returns a value between 0 and 1.

setCaption(id: string) : Promise<void>

Update current caption using the caption id.

getCaptions(): Promise<{ id: string, label: string, src: string, mode: 'disabled' | 'showing' }>

Get video captions.

Events

You can subscribe to events by using addEventListener(). See above for details.

Event playbackStatusUpdate

Fired every half second to provide the current status of playback. The parameter of the callback will resemble:

{
  "position": 22.3,
  "volume": 0.9,
  "duration": "171.37499",
  "playbackState": "playing"
}

duration field and ended playbackState are available in PeerTube >= 2.2.

The volume field contains the volume from 0 (silent) to 1 (full volume). The playbackState can be unstarted, playing, paused or ended. More states may be added later.

Event playbackStatusChange

Fired when playback transitions between states, such as paused and playing. More states may be added later.

Event resolutionUpdate

Fired when the available resolutions have changed, or when the currently selected resolution has changed. Listener should call getResolutions() to get the updated information.

Event volumeChange

Fired when the player volume changed.
