Youtube-dl télécharge Js player

La discussion sur #youtube-dl IRC freenode pourtant (a confirmer)ne me satisfait pas, (manque d'information supléméntaire), il semble qu'un JS soit belle et bien executer (Libre ou pas!)

Hi everyone i just have a question about why i get Downloading js (javascript player) on certain videos while on other downloads i just get Extracting video information ? thanks ;-)what actually is this js player ?
10:39 Some services use javascript that isn't easily reverse engineered (eg. security keys)
10:40 GPG keys in javascript ?
10:42 why do i need Javascript on a MP4 download?
10:43 What site are you downloading from
10:43 mu point is if i download Javascript, can this be malicious?
10:43 *my
10:43 site from Youtube
10:43 The only JS that is downloaded is from Google themselves.
10:45 thanks xxx, nevertheless what does that JS do afterwards? once downloaded in a ~/home/Downloads/
10:45 Nothing. It gets downloaded, interpreted, then deleted
...
10:46 You mean VLC, MGnomePlayer or any othet media player will execute that js ?
10:48 No

10:51 Yes, it downlaods javascript, interprets it, then deletes it. That is all. It is necessary to download the video. THe video has no traces of the javascript.

La solution serait-elle ? :

Run youtube-dl with --write-pages to dump any downloaded pages


Oh, I just must chime in, AGAIN, now. I couldn't resist, needed to make an memè :P
