vision-camera-resize-plugin

A VisionCamera Frame Processor Plugin for fast buffer resizing.

By resizing buffers to a smaller resolution, you can achieve much faster frame processor executions than by running AI on a full-sized (4k) buffer.

Installation

npm install vision-camera-resize-plugin
cd ios && pod install

Add the plugin to your babel.config.js:

module.exports = {
  plugins: [
    [
      'react-native-reanimated/plugin',
      {
        globals: ['__resize'],
      },
    ],

    // ...

Note: You have to restart metro-bundler for changes in the babel.config.js file to take effect.

Usage

{ 'worklet'; if (frame.width > 1920) { frame = resize(frame, 1920, 1080) } // run AI on smaller buffer here }, []); ">

import { resize } from "vision-camera-resize-plugin";

// ...

const frameProcessor = useFrameProcessor((frame) => {
  'worklet';
  if (frame.width > 1920) {
    frame = resize(frame, 1920, 1080)
  }
  // run AI on smaller buffer here
}, []);

Implicit conversion of Objective-C pointer type 'Frame *' to C pointer type 'CMSampleBufferRef'
Hey,

that's exactly the plugin I'd need right now, but it looks like it's not really ready to use (like: at all) 😅

I get an error

Implicit conversion of Objective-C pointer type 'Frame *' to C pointer type 'CMSampleBufferRef' aka 'struct opaqueCMSampleBuffer *') requires a bridged cast

in line 27 and line 30 when I try to create a build in xcode

Also, as somebody else pointed out already: the JS part of this plugin is still the labelImage function. Any chance to get this fixed on the short term? 🙂
