Hosting a livestream

The Video API allows you to assign specific roles for users in a livestream, such as hosts and viewers. Our SDK provides dedicated livestreaming components for both of these roles.

Default component

For the host role, our React Native SDK includes the specialized HostLivestream component.

Here is a preview of the above component in video mode:

import {
  HostLivestream,
  StreamVideo,
  StreamCall,
} from "@stream-io/video-react-native-sdk";

export const MyLivestreamApp = () => {
  // init client and call here...
  return (
    <StreamVideo client={client}>
      <StreamCall call={call}>
        <HostLivestream />
      </StreamCall>
    </StreamVideo>
  );
};

Adding customization

The HostLivestream provides a lot of customization options that can be passed as props:

• HostLivestreamTopView allows customizing the top view or the header of the HostLivestream. It contains the LiveIndicator, FollowerCount, and the DurationBadge component by default.
• LivestreamLayout allows customizing the main video layout component of the HostLivestream.
• HostLivestreamControls allows customizing the bottom livestream controls component of the HostLivestream. It contains the HostStartStreamButton and the LivestreamMediaControls component by default.
• LiveIndicator allows customizing the live indicator component that is present in the top view of the HostLivestream.
• FollowerCount allows customizing the follower count component that is present in the top view of the HostLivestream.
• DurationBadge allows customizing the duration badge that shows the duration of the livestream in the top view of the HostLivestream.
• HostStartStreamButton allows customizing the start/end button of the livestream on the controls of the HostLivestream.
• LivestreamMediaControls allows customizing the media controls button of the livestream on the controls of the HostLivestream.
• onEndStreamHandler allows full override of the default functionality on what should happen when host ends the streaming using HostStartStreamButton.
• onStartStreamHandler allows full override of the default functionality on what should happen when host starts the streaming using HostStartStreamButton.

An example to customize the FollowerCount component is shown below:

import {
  HostLivestream,
  StreamVideo,
  StreamCall,
  useCallStateHooks,
} from "@stream-io/video-react-native-sdk";
import { View, Text, StyleSheet } from "react-native";

const FollowerCountComponent = () => {
  const { useParticipantCount } = useCallStateHooks();
  const totalParticipants = useParticipantCount();

  return (
    <View style={styles.container}>
      <Text style={styles.label}>{totalParticipants}</Text>
    </View>
  );
};

export const MyLivestreamApp = () => {
  // init client and call here...
  return (
    <StreamVideo client={client}>
      <StreamCall call={call}>
        <HostLivestream FollowerCount={FollowerCountComponent} />
      </StreamCall>
    </StreamVideo>
  );
};

const styles = StyleSheet.create({
  container: {
    paddingHorizontal: 8,
    paddingVertical: 4,
    backgroundColor: "gray",
  },
  label: {
    color: "cyan",
    fontSize: 15,
  },
});

Result:
