Yet another Reddit bot...
You need an agent.protobuf (Example) for the Reddit API from graw, and a credentials.go (See credentials.go.sample for an example) for the YouTube API.
Doesn't download anything to the hard drive! The download stream is sent directly to YouTube! i.e. the video is uploaded as it's being downloaded, making the process super fast (under a minute).
Twitch Clips Bot is licensed under the MIT license which can be found here.
