Local Player help

Has anyone been able to get the videos to open in the player locally? I tired the info from Github but cannot get it to work. I have the play.html saved in my download folder. I have tried messing with the address of the stitched video but nothing seems to get it to work. Any help or suggestions would be greatly appreciated.

Turn on the developer console in the browser and you will see the error message. For Chrome it is the F12 key.
