title: React Native - Get frames from expo-camera
body: <p>I have put together an app that detects the coordinates of faces and puts a square around them using expo-camera. What I actually need to do is crop all the faces from the camera stream with 1-second interval, and pass them through a TensorFlowjs model with <a href="https://github.com/tensorflow/tfjs/tree/master/tfjs-react-native" rel="nofollow noreferrer">TensorFlow.js For React Native</a>. I couldn't see anything like that in <a href="https://docs.expo.io/versions/latest/sdk/camera/" rel="nofollow noreferrer">expo-camera documentation</a>, is that possible with some sort of a trick?</p>
