Question: Tips to build this library on top of the WebRTC fork from LiveKit

[tamimattafi]

Hello @devopvoid!
Thank you for this amazing library!

I'm trying to build WebRTC sources to use on Desktop apps, and specifically using this fork: https://github.com/webrtc-sdk/webrtc

According to the few changes made by the fork, it is possible to use the same JNI files from your library with some tweaks. I tried to adjust CMakeLists.txt to clone and sync sources from their branch instead of chromium, but compilation fails with this error:

It seems like the fork uses a newer version of WebRTC, and specifically 6422 (m125) instead of the version used by this library, which is 4844 (m99).

I would appreciate any help with these questions:

1. Are there any plans to update the library to use a newer version of WebRTC?
2. If not, do you have any tips on how to correctly update the sources to use the m125 version?
3. My experience with JNI is very limited, do you have any tips or advice to write the JNI layer from scratch, in case the library isn't compatible with the fork? It already has JNI files for android that can be used as a reference
4. Are you interested in supporting the fork from LiveKit to use the added features? For example End-to-End Encryption

Thank you in advance!
