+1 on SteamTV honestly. It's a great viewing experience, the quality is way better than Twitch, and it's got no ads. Just minimize the chat because everyone is spamming !drop lol.

It auto plays but it honestly is also a good viewing experience. Quality stayed great for me throughout while on my phone.

steam.tv popping off, does it autoplay or something?
