UDP Multicasting - Video Streaming

[root137]

Hello friends,
I want to build a film site which uses Centos 7 as server os. Thus, I need a professional multicast software. I found key words nginx, ffpeg, jwplayer, vlc but articels about them are generally out of date (Centos 6). Are there anyone to know this concept? How film and series sites can multicast? Which softwares and operating systems are used?

You need a multicasting router. It is the responsibility of the router to form and maintain the multicast tree. Some routers support multicast over TCP and some over TCP+UDP (TCP is actually easier). I've only used this with really, really expensive hardware routers (although imagine there are some open source projects that does this, but I've never used them). Your stream server (thing pushing out the video content) pushes it to the multicast address - pointing to the router and the router delivers those streams to "interested" clients (i.e.: clients that have "subscribed" to the multicast group).
