@arjunae Youtube changed the cipher again. Can you edit this patch to comply those changes please. Thanks...

[arjunae]

Yo: Confirmed. But as Youtube seems to change their stuff now on a regular, nearly Monthly base, i dont really feel that i like to do so. Here are some steps so anyone interested can use to find the new positions:

1. start a youtube video - view html-source - search for the string /jsbin/player
2. download or view above found player.js version :
   view-source:https://www.youtube.com/yts/jsbin/player-vflmQAIkc/de_DE/base.js
3. begin at last youtube changes Position - which also introduced "yt.akamaized.net"
4. look at the stuff called after : "d.set(b,(0,window.encodeURIComponent)(pL((0,window.decodeURIComponent)(c))));return d};"
5. find && analyze the function names b, pL , c (eg search for stuff like bL=function)
6. doin that, youll find
   pL=function(a){a=a.split("");oL.uD(a,31);oL.iZ(a,39);oL.uD(a,1);return a.join("")};
   which seems quite similar to what was called before the change:
   bL=function(a){a=a.split("");aL.jl(a,58);aL.NI(a,2);aL.l5(a,35);aL.NI(a,2);aL.jl(a,45);aL.l5(a,4);aL.jl(a,46);return a.join("")};
7. havin verified the (otherwise meaningless) functions name as the decryption function- pL lets see whats changed in the function call in 4)
   d.set("alr","yes");c&&d.set(b,bL(c));return d};
   changed to:
   d.set(b,(0,window.encodeURIComponent)(pL((0,window.decodeURIComponent)(c))));return d};
8. so all you need to do will be adapting the function names regexps $prefix, to reflect the changes made by yt in 7). The result should read pl instead of bl

Add: you will need to read into writeing regexps. but theres much easy to understand docs on the net so:
Happy Hacking!...

PS: @Athlon1600: good job in rewriting the code in a clean manner.

^ That's basically it.

I made the fix:

Check the links from the Demo section. They're working now.

hey@Athlon1600
1- thanks for creating this script!
2- I'm trying to run this script but I can't get it to work properly. I get:

Invalid argument supplied for foreach()
foreach ($instructions as $opt) {
line 182

[Athlon1600]

^ that was fixed here:
cf7f863

do: composer update to get the latest version

[crsurfer]

thanks @Athlon1600, I don't know much about packages but if I do composer update, it doesn't really update the file. but for testing I did copy the code you had in that reference and worked. now I'm getting the URL, but I can't download any video ( access denied )

also this url : https://api.unblockvideos.com/youtube_downloader?id=4Ai63AkrZDk&selector=mp4&redirect=true has an exception.

@Athlon1600 I love you, man!

[Athlon1600]

I don't know much about packages but if I do composer update, it doesn't really update the file.

Try removing your composer.lock file and doing composer update then.

also this url : https://api.unblockvideos.com/youtube_downloader?id=4Ai63AkrZDk&selector=mp4&redirect=true has an exception.

That's because that video is private:

Hello my friend, I do not know how to create an application in heroku. Can you send an explanatory video about creating the application?

[Aniketh01]

How does this project find the manifest file?

[halocedark]

Thank you for this helpful package, however I can get the video to play inside html tag, but I cannot download the video using anchor tag ""

this is the code I use:

`<?php

include_once '../vendor/autoload.php';

use YouTube\YouTubeDownloader;
use YouTube\Exception\YouTubeException;

$youtube = new YouTubeDownloader();

$output = '';

try {
$links = $youtube->getDownloadLinks("https://www.youtube.com/watch?v=cWvR8zsNeDU&list=PLs2aOcA-EaLMzAOFn8ZFuZyq_It6StOOQ");
$formats = $links->getAllFormats();
if ($formats)
{
$output .= '';
$output .= 'Download';
}
else
{
echo 'No links found';
}

} catch (YouTubeException $e) {
echo 'Something went wrong: ' . $e->getMessage();
}

echo $output;
`

When I click on download link, it simply open up new tab and play the video, but I don't want that, I simply want to trigger the browser to download the video.

Guys can you help me please?
