Background
I got really fed up with how bad Twitch was working for me in Firefox. I love both Twitch and Firefox but I got very bad frame rate and theater mode and full screen is more or less unwatchable for me. The problem is present both with and without hardware acceleration enabled in browser. As per usual I blame this on Flash.Chrome handles the Twitch flash player somewhat better but also behaves strangely from time to time, dropping frames and freezing. Not at all as bad as in Firefox
Solution
So I started to look around for a solution and discovered that Twitch do have a HTML5 player but the information around the web is fragmented, outdated and not very reliable. I did find this solution that works fine for me and satisfies my needs. I just use a URL like this, substituting channelname:http://player.twitch.tv/?branding=false&html5&showInfo=false&channel=channelname
The official documentation can be found here but all parameters are not documented and HTML5 is not even mentioned. For example html5, branding and showInfo is not documented and their forum is not much help either.
Example:
Dethfanatics awesome StarCraft II stream
This show only the stream and nothing else, i.e no chat or other information.
Protip: You can use the Youtube HTML5 Video Player page to check if browser support HTML5 video player.
