How to Stream WebRTC H.265 (HEVC) Video in a React Native App?

I am trying to create a React Native app to stream live CCTV footage on a mobile device.

The Problem:

• RTCView from React-Native-WebRTC does not support H.265 (HEVC) decoding. So, I cannot play the WebRTC stream directly inside my React Native app.
• I also tried using react-native-vlc-media-player since it supports H.265 video, but it does not support WebRTC stream URLs.
• As a result, I am unable to play the WebRTC H.265 video inside my React Native app.

What I have tried:

• My CCTV camera provides an RTSP stream.
• To make the stream accessible, I created a gateway using .NET, which extracts the RTSP stream and converts it into a WebRTC stream.
• This setup works perfectly in React.js inside the Safari browser because Safari supports H.265 (HEVC) video.

What I Am Looking For:

I need a way to play WebRTC H.265 (HEVC) video inside a React Native app. Any solution would be helpful, such as:

• A React Native package that supports WebRTC H.265 streaming.
• A custom native module (Java/Kotlin for Android or Objective-C/Swift for iOS) to decode and play H.265 WebRTC streams.
• Any alternative approach that allows me to display the WebRTC H.265 stream inside my React Native app.

If anyone has experience with this or knows of a solution, I would really appreciate your help!

Thanks in advance!

I ended up solving this by embedding WebRTC inside a WebView instead of using RTCView.

react-native-webrtc does not support H.265 (HEVC) decoding, but Chromium-based WebView does (from Chromium 136+) and Safari already supports it.
So instead of rendering the stream with RTCView, I:

• Use a WebView

• Run a pure WebRTC HTML player inside it

• Do SDP offer/answer exchange between React Native ↔ WebView

• Let the browser engine handle H.265 decoding

This works for WebRTC H.265 live CCTV streams without transcoding.

Key points:

• No React Native WebRTC rendering

• WebView handles <video> playback

• RN only acts as a signaling bridge

• Works on iOS (Safari) and Android (Chromium WebView)

This is currently the most practical workaround until native WebRTC adds HEVC support in React Native.
