im after one too...came here to ask same thing so hope you dont mind me tagging along rather than start new thread. ideally like justin.tv
Maybe this script that seems to be released this month will be of some help to your project (they even reference features similar to justin tv): http://www.videowhisper.com/?p=Live+Streaming
I have one for streaming internet TV, but it cant be used for personal webcam profiles like on justin.
Ive one also - - i bought somenthing similar - and modify a bit - but im not a good php programmer - but - the script allow live broadcasting - creation of channels which also they include chat room - autoupdating who is live - instant channel creation (can be inproved) - the script is based on a models rooms chat business - and as said ive modify to make more for a broadcasting use - defenetly a good programmer can go a long way with it ! ive bought it as this kind of scripts are very expensive and nearly impossible to find - but if you consider ive only pay for it us 160 - it is not too bad - but yea - if nothing better will come out - ill than hire somebody to further improve the thing. the example can be see at: www.justclip.tv/main_live.php ray
i am interested in a live sports streaming script as well and I am wondering how to do this and where to find it...do these scripts require you to host the streams..also is this legal?
