Hey all!
I've created a new Workflow controlling Youtube Videos on Google Chrome! I use this mainly for listening to music, but it will work for anything!
You can find the details here: http://www.packal.org/workflow/youtube-control
I have not tested it with any other version other than Mavericks, so some help with testing would be appreciated! Again its only tested witht he latest Google Chrome.
Additionally, this works best with HTML5 video which you can change here https://www.youtube.com/html5
It may break if Youtube updates their layout!
Thanks,
Phil
