SourceHandler setSource check fails on minified version

[matteos]

The new check for setSource method fails on minified js, because setSource is not exported.
In player.js :

        if (window['videojs'][this.techName].prototype.hasOwnProperty('setSource')) {
          this.techCall('setSource', source);
        } else {
          this.techCall('src', source.src);
        }

The new method will never be called when using the minified version.
I've tried adding the property to exports.js and it does resolve the issue.
