Network Quality Indicator

Network conditions are not always perfect so instead of playing guessing games as to why is someone's video so blurry our default ParticipantView component comes equipped with network quality indicator which provides general information about that participants network conditions in four states:

• UNSPECIFIED
• POOR
• GOOD
• EXCELLENT

This is the preview of the Default Network Quality Indicator:

In this guide we'll learn how to build and implement our own primitive network quality indicator:

Custom Network Quality Indicator

You'll most likely be displaying this indicator component inside each participant view (Participant) within a call layout. To achieve the customization you can follow the snippet below:

import { Text, View } from 'react-native';
import {
  useParticipants,
  ParticipantNetworkQualityIndicatorProps,
} from '@stream-io/video-react-native-sdk';

const CustomNetworkQualityIndicator = ({
  participant,
}: ParticipantNetworkQualityIndicatorProps) => {
  return (
    <View style={styles.container}>
      <Text style={styles.connection}>
        {'⭐️'.repeat(participant.connectionQuality)}
      </Text>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    backgroundColor: 'gray',
    borderRadius: 5,
    alignSelf: 'center',
    padding: 5,
  },
  connection: {
    fontSize: 10,
  },
});

Final Steps

Now this can be passed to the ParticipantNetworkQualityIndicator prop of the CallContent component, as follows:

import {
  Call,
  CallContent,
  StreamCall,
} from '@stream-io/video-react-native-sdk';

const VideoCallUI = () => {
  let call: Call;
  // your logic to create a new call or get an existing call

  return (
    <StreamCall call={call}>
      <CallContent
        ParticipantNetworkQualityIndicator={CustomNetworkQualityIndicator}
      />
    </StreamCall>
  );
};

note

To get the participant data, you can use the following hooks from the useCallStateHooks:

• useParticipants hook that provides all the necessary details of all the participants.
• useRemoteParticipants hook that provides all the details of the participants other than the local participant.
• useConnectedUser or useLocalParticipant provides the details of the local or connected participant.
