android_virtual_cam VS CorePatch

Thanks for your response. The real reason why I am trying to do this is just to play a funny video on Discord through my phone camera instead of the screenshare feature. After hours of googling, I found this Github page: "https://github.com/w2016561536/android_virtual_cam/blob/master/README_en.md" but I am stuck on the 1st step of the installation process: Step 1: Install this module and enable it in Xposed. In Lsposed and other frameworks that have a scope list, you need to choose the target app instead of the System Framework. Do you know what Xposed is? If so, how do I download it? Do I need to root my phone in order to download it?

VCAM: create a virtual camera interface on your phone and attach it to different apps

You need to install LSPosed (https://github.com/LSPosed/LSPosed) and Core Patch (https://github.com/LSPosed/CorePatch) and apply it. This does the same thing as the last patch in LP

You need root to do that. Downgrading requires Android Core Patch. There are many apps and modules that can do that like this one https://github.com/LSPosed/CorePatch

signature verification: - https://github.com/LSPosed/CorePatch

Core Patch https://github.com/LSPosed/CorePatch is better than inbuilt patches in LP. No BT bug so far, and everything working great even signature verification.

The solution is to install LSPosed And Core Patch, core patch does the same thing as the 3rd patch In lp

Core Patch: disable signature verification
