To learn, how to render video in the meeting, follow this detailed guide.

Getting Participant Camera Status

• You can get the local participant's media status from the useMeeting hook property named localWebcamOn.
• If localWebcamOn is true, it means that the local participant's camera is currently active. If it is false, it means that the local participant's camera is currently disable or inactive.

import { useMeeting } from "@videosdk.live/react-native-sdk";
const MeetingView = () => {
  // Get the localWebcamOn property
  const { localWebcamOn } = useMeeting();

  return (
    <>
      <Text>Local Camera is {localWebcamOn}</Text>
    </>
  );
};

• To get the status of any participant you can use the webcamOn property of the useParticipant hook. This parameter will be true if participant's camera is on else it will be false.

import { useParticipant } from "@videosdk.live/react-native-sdk";
const ParticipantView = (participantId) => {
  // Get the webcamOn property
  const { webcamOn } = useParticipant(participantId);

  return (
    <>
      <Text>Participant Camera is {webcamOn}</Text>
    </>
  );
};

  function onStreamEnabled(stream) {
    if(stream.kind === 'video'){
      console.log("Video Stream On: onStreamEnabled", stream);
