Compile NGINX with RTMP and setup Multi-Streaming

These Scripts will install NGINX with the RTMP Module in the usual directories similar to installation with apt-get.

The RTMP-Server you get with this can then be used to do one ore more of the following:

• deliver streams in a local network
• deliver streams to websites similar to youtube
• transcode rtmp streams to hls video
• publish to multiple streaming providers
• record livestreams to a harddrive
