For what it's worth, I had this issue, but I didn't follow the example closely enough:

import { RtmpView } from 'react-native-rtmpview';

export default class Example extends Component {
  componentDidMount() {
    // *** This is the key bit!
    this.player.initialize();
    // *** End of key bit!
  }
  
  render() {
    return (
        <RtmpView
          style={styles.player}
          shouldMute={true}
          ref={e => { this.player = e; }}
          onPlaybackState={(data) => {
            this.handlePlaybackState(data);
          }}
          onFirstVideoFrameRendered={(data) => {
            this.handleFirstVideoFrameRendered(data);
          }}
          url="rtmp://localhost:1935/live/stream"
        />
    )
  }
}

Note the componentDidMount() has a this.player.initialize() which is absolutely crucial for initialising all the components properly (and one cannot initialise properly without the ref bit)
