This plugin is not supported

I'm trying to watch an archived webcast of a football game i played 7 years ago. The site says plugin not supported when I go to the viewing page. Is there a way I can edit the source or something I can change on chrome to make this video work?

I was not the creator of this site but perhaps I could temporarily make the page work by changing the media attribute?

Thanks in advance for your help. http://ift.tt/2fbzWxF
