How to use a \"custom\" video capturer to create a VideoTrack and provide frames?
The classic approach to create a VideoTrack is:
1 - Get a VideoCapt
The easiest way (although a bit "hacky") to do this is to copy the source of RTCVideoCapturer
to a local class withing your project and just use that local class. You can now edit the class to suit your needs. Even when not copying the file but actually building your own, it's probably better to copy large parts of the existing capturer than to reinvent the wheel.
