Current version of this plugin does not work. No-opping line 38 by replacing its contents with if True: seems to fix it. I am a total Python noob, so this may not be the best fix, but it worked for me.

@Spotlightsrule Fixed

I would suggest not to use if True:. This causes all videos to be passed through the proxy, putting unnecessary load on it
