Try looking into Livestreamer GUI. I think they found a workaround.Haha, no, sorry.
I figured out the issue; Twitch have added API keys and authentication and stuff so I can't grab the streams any more without their custom Client ID. I'll see what I can do there, but for now it's definitely broken. :3
Also, VoD support, and maybe logins (for those folk who like pay-per-view stuff) when?
