A code snippet implementing the stream.switchDevice method within the Agora.io SDK

.js

// user clicks on an element within the camera list
$('#camera-list a').click(function(event) {
  var index = event.target.id.split('_')[1];
  changeStreamSource (index, "video");
});

// user clicks on an element within the mic list
$('#mic-list a').click(function(event) {
  var index = event.target.id.split('_')[1];
  changeStreamSource (index, "audio");
});

// switch the input device
function changeStreamSource (deviceIndex, deviceType) {
  console.log('Switching stream sources for: ' + deviceType);
  var deviceId;
  var existingStream = false;
  
  if (deviceType === "video") {
    deviceId = devices.cameras[deviceIndex].deviceId
  }

  if(deviceType === "audio") {
    deviceId = devices.mics[deviceIndex].deviceId;
  }

  localStreams.camera.stream.switchDevice(deviceType, deviceId, function(){
    console.log('successfully switched to new device with id: ' + JSON.stringify(deviceId));
    // set the active device ids
    if(deviceType === "audio") {
      localStreams.camera.micId = deviceId;
    } else if (deviceType === "video") {
      localStreams.camera.camId = deviceId;
    } else {
      console.log("unable to determine deviceType: " + deviceType);
    }
  }, function(){
    console.log('failed to switch to new device with id: ' + JSON.stringify(deviceId));
  });
}
