Hi @Bhanu_Pratap,
For rtmp live stream, we are using third party application - ffmpeg. ([Sharing] Video Streaming from Ameba Pro2 to Browser via FFmpeg)
For WebRTC, you can consider our open source FreeRTOS SDK. Refer to this repository for more information. (ameba-rtos-pro2/component/example/kvs_webrtc_mmf/webrtc_app_src at main · Ameba-AIoT/ameba-rtos-pro2 · GitHub)
Thank you.
