# 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:
|
|
|
|
```typescript
|
|
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:
|
|
|
|
```typescript
|
|
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()
|
|
```
|
|
|
|
## Embed URL parameters
|
|
|
|
You can customize PeerTube player by specifying URL query parameters.
|
|
For example `https://my-instance.example.com/videos/embed/52a10666-3a18-4e73-93da-e8d3c12c305a?start=1s&stop=18s&loop=1&autoplay=1&muted=1&warningTitle=0&controlBar=0&peertubeLink=0&p2p=0`
|
|
|
|

|
### `setResolution(resolutionId : number): Promise<void>`
|
|
|
|
Change the current resolution. Pass `-1` for automatic resolution (when available).

|
|
|
|
### `setPlaybackRate(rate: number) : Promise<void>`
|
|
|
|
Set the current playback rate. The passed rate should be a value as returned by `getPlaybackRates()`.
|
|
|

|
## Embed 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:
|
|
|
|
```json
|
|
{
|
|
"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`
|
|
