Getting Started

Importing via npm/Babel/Browserify/webpack
``shell
npm install videojs-errors
`

Then import in your JavaScript
`js
import videojs from 'video.js';
import 'videojs-errors';
`

Installing the styles will depend on your build tool.
Here's an example of including styles with brunch. See Including Module's styles section.


Importing via script tag

The plugin automatically registers itself when you include videojs.errors.js in your page:

`html

`

You probably want to include the default stylesheet, too. It displays error messages as a semi-transparent overlay on top of the video element itself. It's designed to match up fairly well with the default Video.js styles:

`html

`

If you're not a fan of the default styling, you can drop in your own stylesheet. The only new element to worry about is vjs-errors-dialog which is the container for the error messages.

$3

The plugin supports multiple languages when using Video.JS v4.7.3 or greater. In order to add additional language support, add the language file after your plugin as follows:

`html


`

Note: A formatted example is available for Spanish under 'lang/es.js'.

$3

Once you've initialized Video.js, you can activate the errors plugin. The plugin has a set of default error messages for the standard HTML5 video errors keyed off their runtime values:

- MEDIA_ERR_ABORTED (numeric value 1)
- MEDIA_ERR_NETWORK (numeric value 2)
- MEDIA_ERR_DECODE (numeric value 3)
- MEDIA_ERR_SRC_NOT_SUPPORTED (numeric value 4)
- MEDIA_ERR_ENCRYPTED (numeric value 5)

$3

Additionally, some custom errors have been added as reference for future extension.

- MEDIA_ERR_UNKNOWN (value 'unknown')
- PLAYER_ERR_NO_SRC (numeric value -1)
- PLAYER_ERR_TIMEOUT (numeric value -2)
- PLAYER_ERR_DOMAIN_RESTRICTED
- PLAYER_ERR_IP_RESTRICTED
- PLAYER_ERR_GEO_RESTRICTED

Note:

- Custom errors should reference a code value of a string.
- Two of the provided errors use negative numbers for historical reasons, but alpha-numeric/descriptive strings are less likely to cause collision issues.
- Custom errors should have a type beginning with PLAYER_ERR_ versus the standardized MEDIA_ERR to avoid confusion.
- Custom errors can be chosen to be dismissible (boolean value true)

If the video element emits any of those errors, the corresponding error message will be displayed. You can override and add custom error codes by supplying options to the plugin:

`js
player.errors({
errors: {
3: {
headline: 'This is an override for the generic MEDIA_ERR_DECODE',
message: 'This is a custom error message'
}
}
});
`

Or by calling player.errors.extend _after_ initializing the plugin:

`js
player.errors();

player.errors.extend({
3: {
headline: 'This is an override for the generic MEDIA_ERR_DECODE',
message: 'This is a custom error message'
},
foo: {
headline: 'My custom "foo" error',
message: 'A custom "foo" error message.',
type: 'PLAYER_ERR_FOO'
}
});
`

If you define custom error messages, you'll need to let Video.js know when to emit them yourself:

`js
player.error({code: 'foo', dismiss: true});
`

If an error is emitted that doesn't have an associated key, a generic, catch-all message is displayed. You can override that text by supplying a message for the key unknown.

$3

As of v2.0.0, custom errors can be defined without a code. In these cases, the key provided will be used as the code. For example, the custom foo error above could be:

`js
player.errors.extend({
PLAYER_ERR_FOO: {
headline: 'My custom "foo" error',
message: 'A custom "foo" error message.'
}
});
`

The difference here being that one would then trigger it via:

`js
player.error({code: 'PLAYER_ERR_FOO'});
`

$3

After the errors plugin has been initialized on a player, a getAll() method is available on the errors() plugin method. This function returns an object with all the errors the plugin currently understands:

`js
player.errors();

var errors = player.errors.getAll();

console.log(errors['1'].type); // "MEDIA_ERR_ABORTED"
`

$3

After the errors plugin has been initialized on a player, a timeout() method is available on the errors() plugin method.

A new timeout may be set by passing a timeout in milliseconds, e.g. player.errors.timeout(5 * 1000).

Setting the timeout to Infinity or -1` will turn off this check.

If no argument is passed, the current timeout value is returned.

$3

This functions exactly like timeout except the default value is 5 minutes.

Known Issues

On iPhones, default errors are not dismissible. The video element intercepts all user interaction so error message dialogs miss the tap events. If your video is busted anyways, you may not be that upset about this.
