[abdulsalam1]

hi , i'm working on s project and i get confused from something
when i have a long playlist it take a time to have all the json information
the time depending to the number of videos inside the playlist
i saw this website he is working with ajax
http://youtubemultidownloader.com/list.php

i think he use youtube-dl too
try to use any long playlist like this (600 video)
https://www.youtube.com/playlist?list=PL6BA2D5208E8EF161

and all the information came immediately
any idea how that is possible in youtube-dl please ?

my server is ubuntu and i'm working on php

1. --flat-playlist to extract list of videos.
2. Extract each video separately.
