README
A Flutter package for trimming videos
### Features
* Customizable video trimmer.
* Supports two types of trim viewer, fixed length and scrollable.
* Video playback control.
* Retrieving and storing video file.
Also, supports conversion to **GIF**.
> NOTE: Versions `3.0.0` and above uses the "Full" version of Flutter FFmpeg. To install the "LTS" version, use the "x.x.x-LTS" version of this package.
Following image shows the structure of the `TrimViewer`. It consists of the `Duration` on top (displaying the start, end, and scrubber time), `TrimArea` consisting of the thumbnails, and `TrimEditor` which is an overlay that let's you select a portion from the video.
## Example
The [example app](https://github.com/sbis04/video_trimmer/tree/main/example) running on an iPhone 13 Pro device:
## Usage
Add the dependency `video_trimmer` to your **pubspec.yaml** file:
For using main version of FFmpeg package:
```yaml
dependencies:
video_trimmer: ^3.0.0
```
For using LTS version of FFmpeg package:
```yaml
dependencies:
video_trimmer: ^3.0.0-LTS
```
### Android configuration
No additional configuration is needed for using on Android platform. You are good to go!
### iOS configuration
* Add the following keys to your **Info.plist** file, located in `/ios/Runner/Info.plist`:
```
NSCameraUsageDescription
Used to demonstrate image picker plugin
NSMicrophoneUsageDescription
Used to capture audio for image picker plugin
NSPhotoLibraryUsageDescription
Used to demonstrate image picker plugin
```
## FFmpeg Release
This package supports both Main and [LTS version](https://github.com/arthenica/ffmpeg-kit/wiki/LTS-Releases) of the FFmpeg implementation.

## Functionalities
### Loading input video file
```dart
final Trimmer _trimmer = Trimmer();
await _trimmer.loadVideo(videoFile: file);
```
### Saving trimmed video
Returns a string to indicate whether the saving operation was successful.
```dart
await _trimmer
.saveTrimmedVideo(startValue: _startValue, endValue: _endValue)
.then((value) {
setState(() {
_value = value;
});
});
```
### Video playback state
Returns the video playback state. If **true** then the video is playing, otherwise it is paused.
```dart
await _trimmer.videoPlaybackControl(
startValue: _startValue,
endValue: _endValue,
);
```
### Advanced Command
You can use an advanced **FFmpeg** command if you require more customization. Just define your FFmpeg command using the `ffmpegCommand` property and set an output video format using `customVideoFormat`.
Refer to the [Official FFmpeg Documentation](https://ffmpeg.org/documentation.html) for more information.
> **NOTE:** Passing a wrong video format to the `customVideoFormat` property may result in a crash.
```dart
// Example of defining a custom command
// This is already used for creating GIF by
// default, so you do not need to use this.
await _trimmer
.saveTrimmedVideo(
startValue: _startValue,
endValue: _endValue,
ffmpegCommand:
'-vf "fps=10,scale=480:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0',
customVideoFormat: '.gif')
.then((value) {
setState(() {
_value = value;
});
});
```
## Widgets
### Display a video playback area
```dart
VideoViewer(trimmer: _trimmer)
```
### Display the video trimmer area
```dart
TrimViewer(
trimmer: _trimmer,
viewerHeight: 50.0,
viewerWidth: MediaQuery.of(context).size.width,
maxVideoLength: const Duration(seconds: 10),
onChangeStart: (value) => _startValue = value,
onChangeEnd: (value) => _endValue = value,
onChangePlaybackState: (value) =>
setState(() => _isPlaying = value),
)
```
## Example
Before using this example directly in a Flutter app, don't forget to add the `video_trimmer` & `file_picker` packages to your `pubspec.yaml` file.
You can try out this example by replacing the entire content of `main.dart` file of a newly created Flutter project.
```dart
import 'dart:io';
import 'package:file_picker/file_picker.dart';
import 'package:flutter/material.dart';
import 'package:video_trimmer/video_trimmer.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Video Trimmer',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: HomePage(),
);
}
}
class HomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Video Trimmer"),
),
body: Center(
child: Container(
child: ElevatedButton(
child: Text("LOAD VIDEO"),
onPressed: () async {
FilePickerResult? result = await FilePicker.platform.pickFiles(
type: FileType.video,
allowCompression: false,
);
if (result != null) {
File file = File(result.files.single.path!);
Navigator.of(context).push(
MaterialPageRoute(builder: (context) {
return TrimmerView(file);
}),
);
}
},
),
),
),
);
}
}
class TrimmerView extends StatefulWidget {
final File file;
TrimmerView(this.file);
@override
_TrimmerViewState createState() => _TrimmerViewState();
}
class _TrimmerViewState extends State {
final Trimmer _trimmer = Trimmer();
double _startValue = 0.0;
double _endValue = 0.0;
bool _isPlaying = false;
bool _progressVisibility = false;
Future _saveVideo() async {
setState(() {
_progressVisibility = true;
});
String? _value;
await _trimmer
.saveTrimmedVideo(startValue: _startValue, endValue: _endValue)
.then((value) {
setState(() {
_progressVisibility = false;
_value = value;
});
});
return _value;
}
void _loadVideo() {
_trimmer.loadVideo(videoFile: widget.file);
}
@override
void initState() {
super.initState();
_loadVideo();
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Video Trimmer"),
),
body: Builder(
builder: (context) => Center(
child: Container(

_saveVideo().then((outputPath) {
print('OUTPUT PATH: $outputPath');
final snackBar = SnackBar(
content: Text('Video Saved successfully'));
ScaffoldMessenger.of(context).showSnackBar(
snackBar,
);
});
},
child: Text("SAVE"),
),
Expanded(
child: VideoViewer(trimmer: _trimmer),
),
Center(
child: TrimViewer(
trimmer: _trimmer,
viewerHeight: 50.0,
viewerWidth: MediaQuery.of(context).size.width,
maxVideoLength: const Duration(seconds: 10),
onChangeStart: (value) => _startValue = value,
onChangeEnd: (value) => _endValue = value,
onChangePlaybackState: (value) =>
setState(() => _isPlaying = value),
),
),
TextButton(
child: _isPlaying
? Icon(
Icons.pause,
size: 80.0,
color: Colors.white,
)
: Icon(
Icons.play_arrow,
size: 80.0,
color: Colors.white,
),
onPressed: () async {
bool playbackState = await _trimmer.videoPlaybackControl(
startValue: _startValue,
endValue: _endValue,
);
setState(() {
_isPlaying = playbackState;
});
},
)
],
),
),
),
),
);
}
}
```
## Troubleshooting LTS version
While running on the Android platform if it gives an error that the `minSdkVersion` needs to be `24`, or on iOS platform that the Podfile platform version should be `11`, first go to `pubspec.lock` file and see if the version of `ffmpeg_kit_flutter` has `-LTS` suffix. This should fix all issues for iOS platform.
On Android, if you still face the same issue, try adding the following to the `/android/app/src/main/AndroidManifest.xml`:
```
```
