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).

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.

I suggest using io.popen() and reading its output instead of writing a file, maybe it would be faster?
Also is it possible to play the video provided in the playlist link (watch?v=) instead of playing the playlist from the beginning? it used to work that way with the old script, so i am sure the logic can be found there.
I would help, but i am not well versed in Lua.

Nice suggestion. I will try to use it. Could please provide an example of the link that contains the video of the playlist?
Thank you

A random playlist:
https://www.youtube.com/playlist?list=PLbpi6ZahtOH4pokHV8yY5mk42_cMRMK8s

2nd video:
https://www.youtube.com/watch?v=hFZFjoX2cGg&list=PLbpi6ZahtOH4pokHV8yY5mk42_cMRMK8s&index=2

If you use the second link in VLC, it starts playing from the 1st video instead of the 2nd one.

Works wonderfully, once you realize that you don't want the ytdl LUA! Thank you very much for updating the script's code!

Edit: YTDL & FFmpeg (for Windows 10, versions 1909 & higher) must be installed to your System's Environment Variables under System Variables > Path (This cannot be automated non-destructively.)
The 32-bit install of VLC (via MSI installer) might also be required.

I have 0 ways of testing this with Mac & Linux.

This should be quite easy to implement. I will try to add this feature in the next version.

How do you want this to work? vlc should start playing the playlist from the second video and then continue with the third? Where should the first video of the playlist be in vlc playlist? It cannot be in the first position because, otherwise, vlc will play it as first. AFAIK in a playlist extension I cannot tell vlc to skip a video.

It should play the 2nd, then 3rd and so on yes. And the 1st one remains before the 2nd one, but doesn't play initially. It used to work that way with the other one, i am not sure how they did it though.

For more clarification:

VLC playlist:
1st video
2nd video <- plays initially
3rd video <- plays next

For reference, ytdl lua (which I didn't know existed) works similarly and uses io.popen already, might be a nice reference.

I edited the script to use io.popen instead of os.execute. This way the intermediate file is not generated anymore. However that did not speed up the process noticeably.

Honestly I don't see how this can be done with vlc playlist lua API. I can create the playlist without the first video or putting the first video at the end. Starting to play the playlist from the second video seems not feasible to me. If anyone knows how this can be done, please suggest.

It does not work for me.
Here are the logs:

Did you copy JSON.lua in the same directory of the script lua file?

That is a problem with youtube vlc extension.
Today youtube modified something in get_video_info interface and now even youtube vlc playlist extension does not work anymore.
I hope the wil fix it soon (if it can be fixed). In the meanwhile the only workaround is to use ytdl lua

I have updated VLC and it is better now, but most videos can't play from any music/copyright channels.

Yeah my FlagPlayer broke as well on some videos, YouTube slightly changed formats for parts of their stream encoding. But that's not likely the issue you were having with youtube-dl, my older version works just fine on some of these videos.
Basically youtube checks if the IP that requested the webpage is the same as the one requesting the stream, for some copyrighted videos, which might be what you're experiencing - although I don't know why youtube-dl would be using a proxy, so not sure if that is actually the problem.
Can you share a link that currently does not work with youtube-dl?

Hi, I worked on a version that use the code source of the playlist to extract the data (I use the ytInitialData from javascript to get the data), it works with /watch?v=XXX&list=XXXX and /playlist?list=XXXX urls and I want to add support of music.youtube.com/watch?list=XXX and music.youtube.com/playlist?list=XXX.

WARNING: if Youtube update there code, my parser will not work any more and will need an update.

The YTDL LUA overrides this script. REMOVE IT.

Hey! I have used this extension before, by some Miracle I figured out how to get it to work. I did something recently, don't know what, I can't remember how to get the Extension to work, it took me hours last time and I am not a Code Genius.

Could someone make a step by step for absolutely brain dead people like me and others? We'd really appreciate it, a short video would be great!

Edit: Okay, I figured it out, Mostly. So, I reinstalled VLC, fully wiped all it's data. Went into AppData and Roaming, made the Lua and Extensions and Playlist folder. Putting it all in Playlist there, it Works, except it Doesn't.

So, it won't play 90% of the Songs, I guess it's a region Restriction thing, I'm from Australia though and normal browsing I have no Restrictions on the Songs that aren't playing Normally.

How do I go about making VLC play these 'Restricted' Songs?

Not sure tbh but you could try if other custom software has similar issues with it. E.g. I made FlagPlayer and there are certain copyrighted videos it can't play if it is using a public proxy server (default, though you can easily host one locally). VLC should not have a problem with that due to not being a website, I would expect it to play back all videos. So if you find FlagPlayer can play them, I would file a bug with VLC (or the maintainer of the YouTube watch plugin, not this one). If it can't, it should give you some idea to why (you could even send me a link if it's not clear why and I'll test).
https://flagplayer.seneral.dev/ (Comments are broken again and there's a weird video length bug only on firefox but apart from that videos should play fine).
One thing I will say is that YouTube sometimes just doesn't load a video, both through FlagPlayer or the official website, until you reload. Not sure if YouTube detects foreign traffic by other programs and adds unreliability after some time, but got nothing to compare with to verify.

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
