# 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()
|
|
```
|
|
|
|
# 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:
|
|
|
|
```json
|
|
{
|
|
"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`.
|
|
|
|
# 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"
|
|
}
|
|
```
|
|
|
|
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.
