Native Video Editing/trimming/compressing Library for React-Native


Getting Started

npm install react-native-video-processing --save
yarn add react-native-video-processing

You can check test by running

$ npm test or $ yarn test


Note: For RN 0.4x use 1.0 version, for RN 0.3x use 0.16


  • Open up android/app/src/main/java/[...]/

  • Add import com.shahenlibrary.RNVideoProcessingPackage; to the imports at the top of the file

  • Add new new RNVideoProcessingPackage() to the list returned by the getPackages() method

  • Append the following lines to android/settings.gradle:

include ':react-native-video-processing'
project(':react-native-video-processing').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-video-processing/android')

  • Insert the following lines inside the dependencies block in android/app/build.gradle:
    compile project(':react-native-video-processing')

  • Add the following lines to AndroidManifest.xml:
   <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>


  1. In Xcode, right click your Xcode project and create New Group called RNVideoProcessing.

  2. Go to node_modules/react-native-video-processing/ios/RNVideoProcessing and drag the .swift files under the group you just created. Press Create folder references option if not pressed.

  3. Repeat steps 1 & 2 for the subdirectories RNVideoTrimmer, RNTrimmerView, and ICGVideoTrimmer and all the files underneath them. Make sure you keep the folders hierarchy the same.

  4. Go to node_modules/react-native-video-processing/ios/GPUImage/framework and drag GPUImage.xcodeproj to your project’s root directory in Xcode.

    Project Structure

  5. Under your project’s Build Phases, make sure the .swift files you added appear under Compile Sources.

  6. Under your project’s General tab, add the following frameworks to Linked Frameworks and Libraries :

  • CoreMedia
  • CoreVideo
  • OpenGLES
  • AVFoundation
  • QuartzCore
  • MobileCoreServices
  • GPUImage
  1. Add GPUImage.frameworkiOS to Embedded Binaries.

  2. Navigate to your project’s bridging header file <ProjectName-Bridging-Header.h> and add #import "RNVideoProcessing.h".

  3. Clean and run your project.

Check the following video for more setup reference.


Update ffmpeg binaries

  1. Clone mobile-ffmpeg
  2. Setup project, see Prerequisites in README.
  3. Modify build/ so it generates binaries (more info)
    1. Delete --disable-programs line
    2. Change --disable-static line to --enable-static
    3. Delete --enable-shared line
  4. Compile binaries: ./ --lts --disable-arm-v7a-neon --enable-x264 --enable-gpl --speed. The command might finish with failed. That’s okay because we modified the build script. Make sure every build outputs: ffmpeg: ok.
  5. Find ffmpeg binaries in prebuilt/[android-arm|android-arm64|android-x86|android-x86_64]/ffmpeg/bin/ffmpeg
  6. Copy and rename binaries to android/src/main/jniLibs/[armeabi-v7a|arm64-v8a|x86|x86_64]/ Make sure you rename the binaries from ffmpeg to!

Example Usage

import React, { Component } from 'react';
import { View } from 'react-native';
import { VideoPlayer, Trimmer } from 'react-native-video-processing';

class App extends Component {
    trimVideo() {
        const options = {
            startTime: 0,
            endTime: 15,
            quality: VideoPlayer.Constants.quality.QUALITY_1280x720, // iOS only
            saveToCameraRoll: true, // default is false // iOS only
            saveWithCurrentDate: true, // default is false // iOS only
            .then((newSource) => console.log(newSource))

    compressVideo() {
        const options = {
            width: 720,
            height: 1280,
            bitrateMultiplier: 3,
            saveToCameraRoll: true, // default is false, iOS only
            saveWithCurrentDate: true, // default is false, iOS only
            minimumBitrate: 300000,
            removeAudio: true, // default is false
            .then((newSource) => console.log(newSource))

    getPreviewImageForSecond(second) {
        const maximumSize = { width: 640, height: 1024 }; // default is { width: 1080, height: 1080 } iOS only
        this.videoPlayerRef.getPreviewForSecond(second, maximumSize) // maximumSize is iOS only
        .then((base64String) => console.log('This is BASE64 of image', base64String))

    getVideoInfo() {
        .then((info) => console.log(info))

    render() {
        return (
            <View style={{ flex: 1 }}>
                    ref={ref => this.videoPlayerRef = ref}
                    startTime={30}  // seconds
                    endTime={120}   // seconds
                    play={true}     // default false
                    replay={true}   // should player play video again if it's ended
                    rotate={true}   // use this prop to rotate video if it captured in landscape mode iOS only
                    playerWidth={300} // iOS only
                    playerHeight={500} // iOS only
                    style={{ backgroundColor: 'black' }}
                    onChange={({ nativeEvent }) => console.log({ nativeEvent })} // get Current time on every second
                    onTrackerMove={(e) => console.log(e.currentTime)} // iOS only
                    currentTime={} // use this prop to set tracker position iOS only
                    themeColor={'white'} // iOS only
                    thumbWidth={30} // iOS only
                    trackerColor={'green'} // iOS only
                    onChange={(e) => console.log(e.startTime, e.endTime)}

Or you can use ProcessingManager without mounting VideoPlayer component:

import React, { Component } from 'react';
import { View } from 'react-native';
import { ProcessingManager } from 'react-native-video-processing';
export class App extends Component {
  componentWillMount() {
    const { source } = this.props;
      .then(({ duration, size, frameRate, bitrate }) => console.log(duration, size, frameRate, bitrate));

    // on iOS it's possible to trim remote files by using remote file as source
    ProcessingManager.trim(source, options) // like VideoPlayer trim options
          .then((data) => console.log(data));

    ProcessingManager.compress(source, options) // like VideoPlayer compress options
              .then((data) => console.log(data));

    ProcessingManager.reverse(source) // reverses the source video 
              .then((data) => console.log(data)); // returns the new file source

    ProcessingManager.boomerang(source) // creates a "boomerang" of the surce video (plays forward then plays backwards)
              .then((data) => console.log(data)); // returns the new file source

    const maximumSize = { width: 100, height: 200 };
    ProcessingManager.getPreviewForSecond(source, forSecond, maximumSize)
      .then((data) => console.log(data))
  render() {
    return <View />;

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
