Open Streaming Platform (OSP) is an open-source, RTMP streamer software front-end for Arut's Nginx-RTMP Module. OSP was designed as a self-hosted alternative to services such as Twitch.tv, Ustream.tv, Mixer, and Youtube Live.
This service is based on an older software version beta6d and not on the current version 0.8.8 because an docker image ist not available for it right now.
