getUserMedia() and webRTC, modify the buffer before sending

I've tried researching this on my own, but fell short.

Let's say I use getUserMedia() and webRTC to make video calls. Is it possible to hook between the getUserMedia() and webRTC and modify the buffer before it is sent?

Simplest example: Sender base64 encodes the buffer before sending it, receiver decodes it and sending and receiving software is none the wiser that that is happening in the background?

Solution

  • You can make it with WebRTC Encoded Transform.

    Here is an official example of End-to-End Encryption.
