Modified VLC YouTube playlist parsing script. The original script was not working anymore because youtube removed the list_ajax interface. Unfortunately the new interface requires at least http GET method with proper headers and they are not supported by vlc. So this version makes use of an external program (youtube-dl). Disclaimer: this version…

MODified by Kai Gillmann, 19.01.2013, kaigillmann@googlemail.com:
VLC HAS already a youtube importer, but not for playlists. IMO this mentioned one is
better than this one, because it opens the video in the best possible video resolution.
So i decided to remove all parts of the code which is not responsible for list handling.
Now this lua script parses the list, as wanted, but for each video opened, the vlc default
Youtube script is used, so the videos will be displayed properly.

Patched by Aaron Hill (https://github.com/seraku24), 2018-05-16:
The original script was failing in VLC 3.x due to an overzealous probe function.
This patch makes the probe function more restrictive to avoid false positives.

Disclaimer: this version works only under Windows. It can be easily ported but I have no way to test
it on other OS at the moment.
Installation (under Windows): place this file in the lua playlist vlc folder together with JSON.lua
(http://regex.info/code/JSON.lua) and youtube-dl.exe (https://youtube-dl.org/latest)

For those unable to play most videos (403 HTTP error), i have updated the youtube.lua script to use youtube-dl to get the link. Updated script
