i recommend at least reanimated 2.3-betha-2, 2.2.0 don't have an important PR of mrousavy, and you i'll experience a lot of issues.

The README.md example doesn't include import 'react-native-reanimated' so that might be tripping people up. The example shouldn't work without it...

[rodgomesc]

make sure that you followed all installation steps for react-native-reanimated in installation instructions

@thanhnh-implvn I ran into the same issue today. @rodgomesc is right, this was a problem with react-native-reanimated's installation. More specifically, the following directions from their docs fixed this for me (from https://github.com/mrousavy/react-native-vision-camera/blob/main/docs/docs/guides/FRAME_PROCESSORS.mdx#what-are-frame-processors)

:::note Frame Processors require react-native-reanimated 2.2.0 or higher. Also make sure to add

import 'react-native-reanimated'
to the top of the file when using useFrameProcessor. :::

Note, you need to add this to the top of your index.js or index.ts file at the root of your app (NOT the file with useFrameProcessor - they need to clarify this in their docs). See in the example app in this repo https://github.com/rodgomesc/vision-camera-qrcode-scanner/blob/master/example/index.tsx

Hope this fixes your issue!
