See Detailed requirements.
I need a script that converts youtube (And other videos from other video sites) into MP3 format.
The user will enter a YouTube url, then it will take him to the next page where he sees a progressbar and when the progress in done he will get the link. When he clicks the link it will automatically start to download the MP3.
The landingpage he lands on when the file is converted will be unique to that particular video so he can share the link with anyone.
The download URL, name of vid, description of vid, URL of vid and image of vid will be available in php strings so I can put them whereever I want.
There must be a system which prevents the user to share the actual link. If he wants to share he must share a link to my page like [[url removed, login to view]://[url removed, login to view] ]. The link shuld expire or something after 1-2 hours. When a friend of him enters [url removed, login to view] it will load a new download link for him.
The script must of cource work in every browser and OS.
