Device Questions

Questions Overview​

I do not see a preview of my camera. What can this be?​

This can have multiple reasons. First be sure to listen to the proper events for device handling - please listen to the event StartPreviewError to see why the camera/preview is not working correctly.

I am trying to preview my camera but I get an error message. What can this be?​

  1. There is no camera connected.
  2. Camera is being used by another browser.

I want to toggle my video device. How can I achieve this?​

You can not switch cameras/devices while a broadcast is active. Please stop the broadcast, switch camera/device and then start the broadcast again. Unfortunately we do not have an example for device toggling, you receive a list of available devices in the ReceivedDeviceList event. Please also add at least logs to the error handlers so you can see if something goes wrong:

user.on("StartPreviewError", function(evt) {
  // handle error
console.log((event.data.text);
});
user.on("StartBroadcastError", function(evt){
// handle error
console.log((event.data.text);
});
