Streaming Video SCRIPT (php, ffmpeg) -- 2

i need a script that i can install in a linux server so from it i can restream links (maybe u can use ffmpeg or any other solutin but i think ffmpeg gives more options and its faster and better ) So in that script i can : 1. add source link - and then chose a command to restream (example 1000k , 500k differents formats , etc) 2. i want to be able to control how much visitor i can see the link (so when i create stream i can write how much visitors i want to allow at the same time) 3. Logs to see how much user see the link and if is possible from what page they see it (so page,ip useragent whatever u can provide will be better) 4. if source fail to be any option to restart stream automatically i will install this script in my dedicated server so u can tell me what to install on it, centos/ubutnu/ apache/nginx just i want to be sure that it will be stable for streaming video u can tell me which is best way to get videos via http or to send form pc to my server via rtmp
