Portal

The `Poster` component displays a visual placeholder for media content prior to playback.

Poster

The `Broadcast.Root` component is the React Context wrapper for Broadcast.

The `Container` component is the container element for Broadcast. It wraps all other elements and acts as an aspect ratio container by default.

The `Video` component is a container for previewing broadcast video content.

The `EnabledTrigger` and `EnabledIndicator` components provide broadcasters with interactive controls and visual cues to manage the "enabled" state of the broadcast.

Authentication

The Assets API is used to create, retrieve, update, delete assets object from pipeline.

To upload an asset, your first need to request for a direct upload URL
and only then actually upload the contents of the asset.
\
\
Once you created a upload link, you have 2 options, resumable or direct
upload. For a more reliable experience, you should use resumable uploads
which will work better for users with unreliable or slow network
connections. If you want a simpler implementation though, you should
just use a direct upload.


## Direct Upload
For a direct upload, make a PUT request to the URL received in the url
field of the response above, with the raw video file as the request
body. response above:


## Resumable Upload
Livepeer supports resumable uploads via Tus. This section provides a
simple example of how to use tus-js-client to upload a video file.
\
\
From the previous section, we generated a URL to upload a video file to
Livepeer on POST /api/asset/request-upload. You should use the
tusEndpoint field of the response to upload the video file and track the
progress:

```
# This assumes there is an `input` element of `type="file"` with id
`fileInput` in the HTML


const input = document.getElementById('fileInput');

const file = input.files[0];

const upload = new tus.Upload(file, {
  endpoint: tusEndpoint, // URL from `tusEndpoint` field in the
`/request-upload` response
  metadata: {
    filename,
    filetype: 'video/mp4',
  },
  uploadSize: file.size,
  onError(err) {
    console.error('Error uploading file:', err);
  },
  onProgress(bytesUploaded, bytesTotal) {
    const percentage = ((bytesUploaded / bytesTotal) * 100).toFixed(2);
    console.log('Uploaded ' + percentage + '%');
  },
  onSuccess() {
    console.log('Upload finished:', upload.url);
  },
});

const previousUploads = await upload.findPreviousUploads();

if (previousUploads.length > 0) {
  upload.resumeFromPreviousUpload(previousUploads[0]);
}

upload.start();

```

> Note: If you are using tus from node.js, you need to add a custom URL
storage to enable resuming from previous uploads. On the browser, this
is enabled by default using local storage. In node.js, add urlStorage:
new tus.FileUrlStorage("path/to/tmp/file"), to the UploadFile object
definition above.

The Livestream API is used to create, retrieve, update, delete stream object from pipeline.

The only parameter you are required to set is the name of your stream,
but we also highly recommend that you define transcoding profiles
parameter that suits your specific broadcasting configuration.
\
\
If you do not define transcoding rendition profiles when creating the
stream, a default set of profiles will be used. These profiles include
240p,  360p, 480p and 720p.
\
\
The playback policy is set to public by default for new streams. It can
also be added upon the creation of a new stream by adding
`"playbackPolicy": {"type": "jwt"}`


Retrieve a livestream

Update a livestream

`DELETE /stream/{id}/terminate` can be used to terminate an ongoing
session on a live stream. Unlike suspending the stream, it allows the
streamer to restart streaming even immediately, but it will force
terminate the current session and stop the recording.
\
\
A 204 No Content status response indicates the stream was successfully
terminated.


Terminates a livestream

Add a multistream target

Remove a multistream target


This will also suspend any active stream sessions, so make sure to wait
until the stream has finished. To explicitly interrupt an active
session, consider instead updating the suspended field in the stream
using the PATCH stream API.


Delete a livestream

Retrieve all livestreams

Retrieve clips of a livestream

The Multistream target API is used to create, retrieve, update, delete multi-stream targets object from pipeline.

Make sure to remove any references to the target on existing
streams before actually deleting it from the API.

The Sessions API is used to retrieve sessions object from pipeline.

Retrieve all sessions

Retrieve recorded sessions

Retrieve clips of a session

The Access control API is used to create, retrieve, update, delete signing keys object from pipeline.


The publicKey is a representation of the public key, encoded as base 64 and is passed as a string, and  the privateKey is displayed only on creation. This is the only moment where the client can save the private key, otherwise it will be lost. Remember to decode your string when signing JWTs.
Up to 10 signing keys can be generated, after that you must delete at least one signing key to create a new one.

The Webhooks API is used to create, retrieve, update, delete webhooks object from pipeline.

To create a new webhook, you need to make an API call with the events you want to listen for and the URL that will be called when those events occur.

The Tasks API is used to retrieve tasks object from pipeline.

The Playback API is used to retrieve playback object from pipeline.

The Transcode API is used to create transcode object from pipeline.

`POST /transcode` transcodes a video file and uploads the results to the
specified storage service.
\
\
Transcoding is asynchronous so you will need to check the status of the
task in order to determine when transcoding is complete. The `id` field
in the response is the unique ID for the transcoding `Task`. The task
status can be queried using the [GET tasks
endpoint](https://docs.livepeer.org/reference/api/get-tasks):
\
\
When `status.phase` is `completed`,  transcoding will be complete and
the results will be stored in the storage service and the specified
output location.
\
\
The results will be available under `params.outputs.hls.path` and
`params.outputs.mp4.path` in the specified storage service.
## Input
\
This endpoint currently supports the following inputs:
- HTTP
- S3 API Compatible Service
\
\
**HTTP**
\
A public HTTP URL can be used to read a video file.
```json
{
    "url": "https://www.example.com/video.mp4"
}
```
| Name | Type   | Description                          |
| ---- | ------ | ------------------------------------ |
| url  | string | A public HTTP URL for the video file. |

Note: For IPFS HTTP gateway URLs, the API currently only supports “path
style” URLs and does not support “subdomain style” URLs. The API will
support both styles of URLs in a future update.
\
\
**S3 API Compatible Service**
\
\
S3 credentials can be used to authenticate with a S3 API compatible
service to read a video file.

```json
{
    "type": "s3",
    "endpoint": "https://gateway.storjshare.io",
    "credentials": {
        "accessKeyId": "$ACCESS_KEY_ID",
        "secretAccessKey": "$SECRET_ACCESS_KEY"
    },
    "bucket": "inbucket",
    "path": "/video/source.mp4"
}
```


## Storage
\
This endpoint currently supports the following storage services:
- S3 API Compatible Service
- Web3 Storage
\
\
**S3 API Compatible Service**
```json
{
  "type": "s3",
    "endpoint": "https://gateway.storjshare.io",
    "credentials": {
        "accessKeyId": "$ACCESS_KEY_ID",
        "secretAccessKey": "$SECRET_ACCESS_KEY"
    },
    "bucket": "mybucket"
}
```

**Web3 Storage**

```json
{
  "type": "web3.storage",
    "credentials": {
        "proof": "$UCAN_DELEGATION_PROOF",
    }
}
```



## Outputs
\
This endpoint currently supports the following output types:
- HLS
- MP4

**HLS**

```json
{
  "hls": {
        "path": "/samplevideo/hls"
    }
}
```


**MP4**

```json
{
  "mp4": {
        "path": "/samplevideo/mp4"
    }
}
```


Transcode a video

Requires a private (non-CORS) API key to be used.


Query viewership metrics

Query usage metrics

Allows querying for the public metrics for viewership about a video.
This can be called from the frontend with a CORS key, or even
unauthenticated.


Query public total views metrics

Requires a proof of ownership to be sent in the request, which for now is just the assetId or streamId parameters (1 of those must be in the query-string).
