videojs-plugins
Set of Videojs plugins for playing streams from the Ceeblue cloud.
This plugin contains:
- WebRTCSource, a Videojs WebRTC playback source handler supporting WHEP and the Ceeblue WebSocket custom signaling,
- QualityButton, a plugin to select the video quality for any kind of source implementing videojs-contrib-quality-levels,
- SourceController, a utility class to switch automatically from one Ceeblue source to another (including WebRTC, HLS, LLHLS and DASH)
Table of Contents
Installation
Download the package from @ceeblue/videojs-plugins or build it manually from the github sources:
npm install
npm run build
Include @ceeblue/videojs-plugins in your HTML code as usual with the link to Videojs and this library.
Example:
<script src="https://vjs.zencdn.net/8.7.0/video.min.js"></script>
<script src="./dist/videojs-plugins.js"></script>
WebRTCSource
Parameters
src
The src
field contains the URL of the WebRTC endpoint.
The protocol can be WebSocket (wss
) to get the best of the custom Ceeblue signaling or HTTP (https
) to use the standard WHEP signaling protocol.
Here is the expected format:
[wss|https]://<host>[/<pathname>]/<streamName>[?id=<accessToken>][&audio=<audioTrackId>][&video=<videoTrackId>]
And here is an example of a WebSocket URL:
wss://la-8.live.ceeblue.tv/as+12346f7c-e5db-450b-9603-c3644274779b
The following options can be set in the query:
- id The access token in case the stream is private.
- audio the audio track ID or
none
to disable audio. - video the video track ID or
none
to disable video.
type
It is important for the MIME-type to be empty to use the WebRTC source.
iceserver
Ice-server structure in JSON string format with TURN URL used to establish the WebRTC connection, mainly for TCP fallback.
Do not enclose the object in an array. If you have multiple TURN servers, you can add them in the
urls
array. If not set, the plugin will use the default TURN server
Example:
Replace
<host>
by your endpoint hostname
{
"urls": ["turn:<host>?transport=tcp", "turn:<host>:3478"],
"username": "csc_demo",
"credential": "UtrAFClFFO"
}
audiobutton
false
to disable the WebRTC audio track selection button, true
by default.
data
true
to listen to all timed metadata tracks, false
otherwise. true
by default.
This has no effect on the player, to get the timed metadata in your application you need to use the textTracks() API of Videojs, you can check examples/player.html for a usage example.
Source Object
Call the player.src()
method with a WebRTC URL.
Example:
Replace
<host>
by your endpoint hostname and<streamName>
by your stream name.
<script type="module">
import {} from "/path/to/video.min.js";
import {} from "/path/to/ceeblue/videojs-plugins.min.js";
...
const player = videojs('video-tag');
player.src({
src: 'wss://<host>/<streamName>',
iceserver: '{
"urls": ["turn:<host>?transport=tcp", "turn:<host>:3478"],
"username": "csc_demo",
"credential": "UtrAFClFFO"
}',
audiobutton: true,
data: false
});
player.start();
</script>
<source>
HTML tag
The WebRTC source can be set directly in the HTML Source tag.
Example:
Replace
<host>
by your endpoint hostname and<streamName>
by your stream name.
<script src="//path/to/video.min.js"></script>
<script src="//path/to/ceeblue/videojs-plugins.min.js"></script>
<div id="video_container">
<video id=video-player width=960 height=540 class="video-js vjs-default-skin" controls>
<source src="wss://<host>/webrtc/<streamName>"
iceserver='{"urls": ["turn:<host>?transport=tcp", "turn:<host>:3478"], "username": "csc_demo", "credential": "UtrAFClFFO"}'>
</video>
</div>
<script>
var player = videojs('video-player');
</script>
QualityButton
If you are not using the SourceController, the QualityButton plugin can be called with a simple command to create the video menu button using the qualityLevels of the current source (see videojs-contrib-quality-levels):
<script>
var player = videojs('video-player');
player.qualityButton();
</script>
SourceController
The SourceController allows you to configure fallback sources if the current source is not working (for example, if WebRTC is not supported in the browser). It is also used for seamlessly switching from one source to the other.
The constructor of SourceController
takes three arguments :
- The videojs player,
- The
Connect.Params
, the ceeblue connection parameters (see Connect class), - The list of sources in order of priority. A source can be a string from the
SourceType
list or a Source Object in order to set custom options.
To start the SourceController
call the start()
function with the SourceType
to start with, or no argument to start from the first source.
The
SourceType
object in SourceController.js defines the list of possible sources, The Source object must have thesrc
field and thetype
field set to the MIME type of the source (empty for WebRTC, see WebRTCSource).
Example:
Replace
<endPoint>
by your endPoint,host
by the endPoint hostname and<streamName>
by your stream name.
const sourceController = new SourceController(
player
);
sourceController.on('sourcechanged', (source) => {
console.log('sourcechanged', source); // null means no more sources available
});
sourceController.start(
{
endPoint: '<endPoint>',
streamName: '<streamName>'
query: 'id=<accessToken>'
},
[
{
// A WebRTC source with custom options
src: 'wss://<host>/<streamName>',
iceserver: '{"urls": ["turn:<host>?transport=tcp", "turn:<host>:3478"], "username": "csc_demo", "credential": "UtrAFClFFO"}',
},
'llhls',
'dash',
{
// A fallback source with a custom type
src: 'http://vjs.zencdn.net/v/oceans.mp4',
type: 'video/mp4'
}
]);
Disabling QualityButton
By default the SourceController creates a QualityButton for the current source but you can disable it in the player's options with the qualityButton
option:
const player = videojs(videoEl, { qualityButton: false});
Examples
Examples can be found in the examples/ directory:
- player.html An advanced example using WebRTC, the SourceController, and the QualityButton, with a UI for setting parameters and displaying timed metadata.
- simple-player.html A simple example using SourceController with default parameters.
- webrtc-player.html A simple example with a WebRTC source configured with the HTML
<source>
tag.
All examples include the HTML code to include the library and player, and the JavaScript code to configure the player. You can add query parameters to the URL to test the different options.
For example:
Replace
<host>
with your endpoint host name,<streamName>
with your stream name, and<accessToken>
with the viewer access token provided by the Ceeblue Cloud API (optional, only if the stream is private).
https://localhost:8080/examples/player.html?host=<host>&stream=<streamName>&accessToken=<accessToken>
Documentation
This monorepo also contains built-in documentation about the APIs in the library, which can be built using the following npm command:
npm run docs
