#### [Android]
- Open up android/app/src/main/java/[...]/MainApplication.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:
`


`

#### [iOS]

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

7. Add GPUImage.frameworkiOS to Embedded Binaries.

8. Navigate to your project's bridging header file and add #import "RNVideoProcessing.h".

9. Clean and run your project.

Update ffmpeg binaries


1. Clone mobile-ffmpeg
2. Setup project, see Prerequisites in README.
3. Modify build/android-ffmpeg.sh 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: ./android.sh --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]/libffmpeg.so. Make sure you rename the binaries from ffmpeg to libffmpeg.so!

Example Usage

`javascript
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
};
this.videoPlayerRef.trim(options)
.then((newSource) => console.log(newSource))
.catch(console.warn);
}

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
};
this.videoPlayerRef.compress(options)
.then((newSource) => console.log(newSource))
.catch(console.warn);
}

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))
.catch(console.warn);
}

getVideoInfo() {
this.videoPlayerRef.getVideoInfo()
.then((info) => console.log(info))
.catch(console.warn);
}

render() {
return (

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
source={'file:///sdcard/DCIM/....'}
playerWidth={300} // iOS only
playerHeight={500} // iOS only
style={{ backgroundColor: 'black' }}
resizeMode={VideoPlayer.Constants.resizeMode.CONTAIN}
onChange={({ nativeEvent }) => console.log({ nativeEvent })} // get Current time on every second
/>
source={'file:///sdcard/DCIM/....'}
height={100}
width={300}
onTrackerMove={(e) => console.log(e.currentTime)} // iOS only
currentTime={this.video.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:
`javascript
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;
ProcessingManager.getVideoInfo(source)
.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 ;
}
}
