Please make sure the question is worded well enough to be understood

On my jailbroken iPhone, I came across this tweak, "哔哩哔哩 NoAds," in the BigBoss Repository in Sileo, a package manager for jailbroken devices. Utilizing it allowed me to play 1080p enhanced bitrate videos, 4K videos, and videos with Hi-Res lossless audio without requiring premium, only requiring a free account.

This doesn't work logged out for some reason.

Knowing this, is it possible to use yt-dlp to 'exploit' this? Or doing something like this won't be possible due to a potential DMCA takedown?

(I suspect that the tweak does this by exploiting the '5 times free 1080p+/4K video trials per month' feature on mobile to achieve this, but I'm not entirely sure.)

Tweak information: 哔哩哔哩NoAds - sileo://package/com.swing.bilibili - from http://apt.thebigboss.org/repofiles/cydia/dists/stable

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

Well, the cydia package is no use since it's just a binary
If you can figure out what the package does, or what kind of requests are being sent with it installed, this could probably be implemented; otherwise there is really nothing to go off of.

Unfortunately, I don't believe that I was able to replicate the free premium video after a few initial tries, which leads me to believe that the aforementioned tweak just removes the "Trial" text, making it look like I got access to the premium qualities for free.

I still was able to get some network analysis files (that I personally can't understand), so I'll put them here if it would be of any use:
with tweak 1 - Stream-2024-05-20_210651.har.txt
with tweak 2 - Stream-2024-05-20_212222.har.txt
without tweak 1 - Stream-2024-05-20_214034.har.txt
without tweak 2 - Stream-2024-05-20_214142.har.txt
You should be able to open the files in a more human readable format by removing the .txt file extension and using a .har analyzer, here or here

I'll be closing this issue for now, and if I find any other news, I'll reopen.

A similar script with source code. It is able to play Bilibili video at 1080p without login.
