Trigger Media Play/Pause or Seek

[Fabii23]

I have a couple questions

1. How would I go about triggering "mediaPlay" , "mediaPause" or "mediaSeek" ?
2. How do I load cast starting at a specific time

1.)
I tried adding the snippet below to chrome.cast.js :

chrome.cast.Session.prototype.pause = function (successCallback, errorCallback) {
        if (chrome.cast.isAvailable === false) {
            errorCallback(new chrome.cast.Error(chrome.cast.ErrorCode.API_NOT_INITIALIZED), 'The API is not initialized.', {});
            return;
        }

        execute('mediaPlay', function (err) {
            if (!err) {
                successCallback && successCallback();
            } else {
                handleError(err, errorCallback);
            }
        });
    };

and call is via :

 castSession.pause(
                function successCallback(){
                    log('Pause Cast content');
                }, 
                function errorCallback(){
                    log('Failed to pause content');
                });

This does not seem to work, any ideas ?

2.)

I tried modifying LoadRequest to take a _currentTime parameter

LoadRequest: function (media, _currentTime) {
               this.type = 'LOAD';
               this.sessionId = this.requestId = this.customData = null;
               this.media = media;
               this.autoplay = !0;

               if(_currentTime){
                   this.currentTime  = _currentTime;
               }
           }

Nevermind, silly mistake on my part, I had to copies of the source file and was editing the wrong file. The above prototype extensions work.
