Custom Video Capturer & Renderer in Android Native

Hi! I am new to Jitsi,
I want to develop an Android native application with Jitsi. my requirement is to customize the captured frame and rendering techniques. I have seen the android demo and jitsi-android-sdk but I could not find APIs for receiving network frame or sending local frame. I want to customize frame at native android level not on react-native. Is it possible?, please provide some reference if it is possible with existing jitsi framework.
