Twitch.tv client for Sailfish OS (Ubuntu Touch vesion is in development - see Ubuntu Touch).
The app is available at Jolla Store for both Jolla and Jolla Tablet.
You can find prebuilt rpm packages for armv7 and i486 architectures on releases page.
UT version of TwitchTube is under development. You can look at the current state by opening ubuntu-twitchtube.pro in Ubuntu SDK.
Video playback doesn't work because UT doesn't have HLS support included at the moment. This is also the reason why I'm giving this a rather low priority.
There're some discussions going about including HLS codec, so the situation is likely to change soon enough.
You can contribute to TwitchTube development by reporting an issue or by sending a pull request. Either is always welcome, though latter might be difficult at the moment as codebase is not in the best state (there're some refactorings planned e.g. #13).
