I have a small wrapper of your CVB api written in c++ meant to be called from a C# application in Unity.
This unity project uses a webrtc binary which causes the error below.
This problem does not occur with the M92 webrtc release and does with M107
I’m wondering if anyone else has had this issue or has some clue?
I have also opened an issue with the Unity plugin: https://github.com/Unity-Technologies/com.unity.webrtc/issues/878
