Creating Meeting & Messaging Session
const logger = new ConsoleLogger('MyLogger', LogLevel.INFO);
const deviceController = new DefaultDeviceController(logger);
// You need responses from server-side Chime API. See below for details.
const meetingInfo = /* The response from the CreateMeeting API action */;
const attendeeinfo = /* The response from the CreateAttendee or BatchCreateAttendee API action */;
const configuration = new MeetingSessionConfiguration(meetingInfo, attendeeinfo);
// you will use this meetingSession object for media accesses.
const meetingSession = new DefaultMeetingSession(
configuration,
logger,
deviceController
);
const messagingSession = new DefaultMessagingSession(configuration, logger);
Select I/O Device
Audio Input Device
const audioVideo = this.meetingSession.audioVideo; // audioVideo : AudioVideoFacade
const audioInputDeviceInfo = /* An array item from audioVideo.listAudioInputDevices */;
await audioVideo.chooseAudioInputDevice(audioInputDeviceInfo.deviceId);
const audioOutputDeviceInfo = /* An array item from audioVideo.listAudioOutputDevices */;
await audioVideo.chooseAudioOutputDevice(audioOutputDeviceInfo.deviceId);
Video Input Device
const videoInputDeviceInfo = /* An array item from audioVideo.listVideoInputDevices */;
await audioVideo.chooseVideoInputDevice(videoInputDeviceInfo.deviceId);
// You can pass null to choose none. Video capture will be stopped.
await audioVideo.chooseVideoInputDevice(null);
Start a meeting session
const audioElement = /* HTMLAudioElement object e.g. document.getElementById('audio-element-id') */;
audioVideo.bindAudioElement(audioElement);
const observer = {
audioVideoDidStart: () => {
console.log('Started');
},
audioVideoDidStop: sessionStatus => {
// See the "Stopping a session" section for details.
console.log('Stopped with a session status code: ', sessionStatus.statusCode());
}
};
audioVideo.addObserver(observer);
audioVideo.start(); // Audio streaming startedThat’s all!Your application with secure video conferencing capabilities is ready to launch! Contact Ideas2IT – The Best Custom Software Development Company today to get more details!
