I've got a Haivision Barracuda, which can stream RTMP to a URL (secured by username/password) set in its interface, but have very little experience of streaming video. What software do I need (Windows or Linux, but ideally free or open source at the moment) to set up a server that can provide this URL on which to receive the stream, please?
Can I then rebroadcast that (also as RTMP, to a remote URL endpoint), and how can I view the live stream to test that it's working?
