| ### What are frame processors? | ||||
|  | ||||
| Frame processors are functions that are written in JavaScript (or TypeScript) which can be used to **process frames the camera "sees"**. | ||||
|  | ||||
| For example, you might want to create a QR code scanner _without ever writing native code while still achieving almost-native performance_. Since you can write the scanning part yourself, you can implement a custom QR code system like the one Snapchat uses for Snap-codes. | ||||
|  | ||||
| <div align="center"> | ||||
|   <img src="../img/snap-code.png" width="15%" /> | ||||
| </div> | ||||
| <br /> | ||||
|  | ||||
| Frame processors are by far not limited to QR code detection, other examples include: | ||||
|  | ||||
| * **AI** for **facial recognition** | ||||
| * **AI** for **object detection** | ||||
| * Using **Tensorflow**, **MLKit Vision** or other libraries (if they provide React Native JSI bindings in the form of "react-native-vision-camera plugins") | ||||
| * Creating **realtime video-chats** since you can directly send the camera frames over the network | ||||
| * Creating **snapchat-like filters**, e.g. draw a dog-mask filter over the user's face (WIP) | ||||
| * Creating **color filters** with depth-detection | ||||
| * Using **custom C++ processors** exposed to JS for maximum performance | ||||
|  | ||||
| ### Technical | ||||
|  | ||||
| Frame processors are JS functions that will be **workletized** using [react-native-reanimated](https://github.com/software-mansion/react-native-reanimated). They are created on a **separate thread** using a separate Hermes/JSC Runtime and are **invoked synchronously** without ever going over the bridge. | ||||
|  | ||||
| ### Example | ||||
|  | ||||
| ```tsx | ||||
| function App() { | ||||
|   const frameProcessor = useFrameProcessor((frame) => { | ||||
|     const qrCodes = scanQrCodes(frame) | ||||
|     console.log(qrCodes) | ||||
|   }, []) | ||||
|  | ||||
|   return ( | ||||
|     <Camera frameProcessor={frameProcessor} {...cameraProps} /> | ||||
|   ) | ||||
| } | ||||
| ``` | ||||
|  | ||||
| > FRAME PROCESSORS ARE STILL WIP | ||||
