pytube VS one-click-youtube-dl

Quicker explanation of how Youtube is doing it is at the source code of pytube: https://github.com/tfdahlin/pytube/blob/bb890af3b271a616bbe1...

This is linked from the description of PR 30184 of youtube-dl but @varenc linked to a specific comment (talking about patching Windows builds, AFAICT) which might confuse some people.

I'll even save you the click:

> YouTube's strategy to restrict downloading videos is to send a ciphered version

There are workarounds (detailed very nicely in dirkf’s pull request for youtube-dl):

Pasting the content here for convenience:

Since summer 2021, YouTube has started serving media URLs with a query parameter such as …&n=SXiXBH-xzrjeioPN&…. This now appears to be the default behaviour. Unless the value of this parameter is transformed according to an algorithm delivered in the site player JS, the download speed for the URL is throttled to ~50kB/s.

Solutions for this include:

• implementing a more complete JS interpreter, eg based on PR [jsinterp] Actual JS interpreter¹ #11272;

• using an external JS interpreter (PhantomJS, now unmaintained, is used by some extractors);

• spoofing the Android or iOS client to acquire unthrottled links, as successfully implemented in yt-dlp².

This PR takes a different approach derived from the successful solution used in VLC's youtube.lua (also implemented differently in pytube³). The approach relies on the fact that the challenge algorithm is served in a mini-language within the minified player JS and therefore the specific algorithm can be extracted and executed by interpreting the mini-language without actually running the JS itself. [In parallel with this PR, a separate implementation of this approach was added to yt-dlp⁴.]

The implementation of the mini-language interpreter is directly translated from VLC's n_descramble() Lua function⁵. The result sufficiently resembles the original that it should be straightforward to share changes between the two implementations.

I found a tool that does what i was trying to ask it's called one-click-youtube-dl

Another alternative: I made a tool which allows one-click downloading videos with youtube-dl (no GUI, no command line). Here: https://github.com/baobabKoodaa/one-click-youtube-dl
