I was bored and finished something I wanted to do for a while, I think you might find a use for it. This will basically make a player like on the twitch team page, by grabbing the list of team members, finding the ones that are live and then selecting the one with the most viewers to put into the player, if none are live it will put the most viewed stream on twitch at the moment in the player. This can of course be tweaked for a specific game or another team.
