@Generalize Not sure what you are about to accomplish exactly, but I handle this myself in the backend, by analyzing every 10 seconds the metrics of an all my CDN instances and then just tell VideoJS from which of the Instances the Stream should get pulled, this way Load balancing works pretty well but also requires a lot of code, as you somehow need to set up a metrics endpoint on all your servers that serve content to users and your Backend will fetch and analyze ...

But to get back to your question, in this example I basically overwrite the domain to pull data from, are you about this?:

videojs.Vhs.xhr.beforeRequest = (options: any) => {

      // Set the Authorization header
      options.headers = { Authorization: this.file_response.access_token };

      // Enable withCredentials
      options.withCredentials = true;

      if (options.uri && options.uri.includes('cdn.old.com')) {

        // Replace the placeholder with the actual domain
        options.uri = options.uri.replace('cdn.old.com', 'cdn.new.com');
      }

      return options;
    };

So it should be like this: videojs.Vhs.xhr.beforeRequest

You can replace the xhr function entirely if desired or use the onRequest or onResponse hooks detailed in the docs here: https://github.com/videojs/http-streaming#vhsxhr
