Methods

Function	Parameter	Description	Return
getThumbnail	String path, int quality(1-100)	Return a thumbnail of the video from the input file uri	Uint8List bitmap
startCompress	String path, bool deleteOrigin	Compress the video file and return a new path or path(event stop compress)	String path
stopCompress	None	stop the video being compressed	Future

Usage

Creating instance.

FlutterVideoCompress _flutterVideoCompress = FlutterVideoCompress();

Get a video file thumbnail

final Uint8List _image = await _flutterVideoCompress
  .getThumbnail(path: file.path, quality: 50)

Compress a Video

final String newPath = await _flutterVideoCompress
  .startCompress(path: file.path, deleteOrigin: true);
  
print(newPath);

Stop Compress

await _flutterVideoCompress.stopCompress()

Notice! Android will print InterruptedException, but does not affect the use

import 'package:image_picker/image_picker.dart' show ImagePicker, ImageSource;

void main() => runApp(MyApp());

      print(newPath);
    }
  }

      FlatButton(child: Text('stop compress'), onPressed: _stopCompress),
    ];
    if (_image != null) {
      _list.add(Flexible(child: Image.memory(_image)));
    }
    return _list;

    // dart 2.3

    //   FlatButton(child: Text('stop compress'), onPressed: _stopCompress),
    //   if(_image != null) Flexible(child: Image.memory(_image))
    // ];
    // return _list;
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: const Text('Plugin example app')),
        body: Column(
          crossAxisAlignment: CrossAxisAlignment.stretch,
          children: _builColumnChildren(),
        ),
      ),
    );
  }
}

Notice

If you find that the size of the apk is significantly increased after importing the plugin, it may be due to the following reasons:

• x86 folder is included in you apk (./assets)

• This Package only use ffmpeg without ffprobe,but the ffprobe still in you apk (asssets/arm or assets/x86)

add this config in build.gradle:

• Do not use ignoreAssetsPattern "!x86" in debug mode, the simulator will. crash

android {
 ...

   // to build apk with unnecessary dependence, you might use this config blow
  aaptOptions {
       ignoreAssetsPattern "!x86:!*ffprobe"
  }
  
  buildTypes {
  ...
  
  }
