Clappr

An extensible media player for the web.

README

Huge changes in the latest version. See 0.4.0 version changelog for more information

Clappr is an extensible media player for the web. Your architecture is projected primarily into plugins, adding low accoupling by design to the project and the possibility to add infinitely features easily.

Clappr uses by default the HTMLVideoElement which guarantees support to many platforms. You have the possibility to extends the default HTML5 playback or the playback interface to create one new media support just like a plugin!

Clappr is a composition of two other projects: @clappr/core and @clappr/plugins.

The @clappr/core contains the basic functionalities from Clappr (plugin architecture, class abstractions, public interfaces, events handlers and etc) and the @clappr/plugins are the repository where the plugins maintained by the Clappr team lives. More info about those projects into your repositories.

All Clappr projects are written in *.js using the latest features of ECMAScript.

Clappr is under development but production-ready. Feel free to open issues and send pull requests.

:play_or_pause_button: About Autoplay

Clappr has no control over autoplay Browser Policy.

Therefore, we're not able to execute play and unmute actions sequentially in every situation. There are a series of scenarios where the Browser blocks these actions based on it’s own policy.

Each browser has their own different restrictions, and the usual behavior is to activate the sound only after an user interaction with the player.

For more infos about auto play video policy, you can read these docs:

- Chrome Autoplay Policy

- WebKit Autoplay Policy

Common steps to verify issues

Very often people open issues related to stream not working, freezing, glitching, stopping, and so on. You can try the steps below, taking notes about the results:

try to run the same example at CDN

check the cors headers at your servers

try to run it on hls.js demo page

try to run it on flashls. demo page

try to run on your page the following source: http://www.streambox.fr/playlists/x36xhzz/x36xhzz.m3u8

try different browsers/OS's to see if the problems remain

try to use a tool to check the health of your stream (both input, ie: RTMP, and segmentation, ie: DASH or HLS): like [mediainfo](https://mediaarea.net/MediaInfo) (for instance you could: mediainfo http://www.example.com/my.m3u8, Apple's [mediastreamvalidator](https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/StreamingMediaGuide/UsingHTTPLiveStreaming/UsingHTTPLiveStreaming.html) too, [hls-analyzer](https://github.com/epiclabs-io/hls-analyzer) and etc.

``` sh
//HLS-Analyzer usage example
pip install m3u8
git clone https://github.com/epiclabs-io/hls-analyzer.git
cd hls-analyzer
python hls-analyzer.py http://www.streambox.fr/playlists/x36xhzz/x36xhzz.m3u8
```

How to handle player fatal errors?

Player fatal errors can be handled using onError API event.

``` js
var player = new Clappr.Player({
parent: '#myplayer',
source: 'http://path.to/my/video.mp4',
events: {
onError: function(e) {
// Here the code to handle the error
}
}
});
```

Note: the type of error event object depends on the type of the playback component resolved to play the video.

Example

This is a simple example using the no_op playback to display error messages.

You can try the following Javascript code on Clappr demo page:

``` js
var playerElement = document.getElementById("player-wrapper");
var r = 3; // Retry attempts
var player = new Clappr.Player({
// source: 'http://clappr.io/highline.mp4',
source: 'http://clappr.io/bad_highline.mp4',
disableErrorScreen: true, // Disable the internal error screen plugin
height: 360,
width: 640,
events: {
onError: function(e) {
r--;
var s = player.options.source;
// Replace previous line by the following line to simulate successful recovery
// var s = (r > 2) ? player.options.source : 'http://clappr.io/highline.mp4';
var t = 10;
var retry = function() {
if (t === 0) {
var o = player.options;
o.source = s;
player.configure(o);
return;
}
Clappr.$('#retryCounter').text(t);
t--;
setTimeout(retry, 1000);
};
player.configure({
autoPlay: true,
source: 'playback.error',
playbackNotSupportedMessage: 'Network fatal error.' + ((r > 0)
? ' Retrying in <span id="retryCounter"></span> seconds ...'
: ' All retry attempts failed'),
});
if (r > 0) {
retry();
}
}
}
});
player.attachTo(playerElement);
```

Another example

This example use a custom error container plugin to display error messages.
