Using the reloadSourceOnError Plugin

Call the plugin to activate it:

player.reloadSourceOnError()

Now if the player encounters a fatal error during playback, it will automatically attempt to reload the current source. If the error was caused by a transient browser or networking problem, this can allow playback to continue with a minimum of disruption to your viewers.

The plugin will only restart your player once in a 30 second time span so that your player doesn't get into a reload loop if it encounters non-transient errors. You can tweak the amount of time required between restarts by adjusting the errorInterval option.

If your video URLs are time-sensitive, the original source could be invalid by the time an error occurs. If that's the case, you can provide a getSource callback to regenerate a valid source object. In your callback, the this keyword is a reference to the player that errored. The first argument to getSource is a function. Invoke that function and pass in your new source object when you're ready.

player.reloadSourceOnError({

  // getSource allows you to override the source object used when an error occurs
  getSource: function(reload) {
    console.log('Reloading because of an error');

    // call reload() with a fresh source object
    // you can do this step asynchronously if you want (but the error dialog will
    // show up while you're waiting)
    reload({
      src: 'https://example.com/index.m3u8?token=abc123ef789',
      type: 'application/x-mpegURL'
    });
  },

  // errorInterval specifies the minimum amount of seconds that must pass before
  // another reload will be attempted
  errorInterval: 5
});
