Youtube-dl Proxy

Minimal (very dirty) script executing youtube-dl and displaying video in the web browser. Place in folder with the “youtube-dl” binary (non included), and open in web browser like this:

http(s)://domain.tld/watch?v=aqz-KE-bpKQ

(note: video is actually downloaded server-side, so make sure to have enough disk space and PHP script execution time while youtube-dl processes the video)
