So let’s use these features to implement a profile picture taker in our Conference app. I’ve included the framework for a camera control in the Conference app already. You’ll need to fill in the interesting bits here. First, here’s the code that gets called when the user starts up the camera. And right here, you need to fill in the code that asks for access to the webcam. Note that we’ve already set up constraints for you. And you have success and error callbacks defined down below. Fill out the code for this function right here, now.
