Before Android installation

If your program not enabled AndroidX, you will need to add the following code to the last line of the android/build.gradle file.

rootProject.allprojects {
    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'androidx.core' && !details.requested.name.contains('androidx')) {
                    details.useVersion "1.0.1"
                }
            }
        }
    }
}

Before IOS installation

If your program not support swift, you need to add the following code in ios/Podfile.detail

target 'Runner' do
  use_frameworks! # <--- add this
  ...
end

# -----insert code start-----
pre_install do |installer|
  installer.analysis_result.specifications.each do |s|
      if s.name == 'Regift'
        s.swift_version = '4.0'
    # elsif s.name == 'other-Plugin'
    #   s.swift_version = '5.0'
    # else
    #   s.swift_version = '4.0'
      end
  end
end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['ENABLE_BITCODE'] = 'NO'
    end
  end
end
# -----insert code end-----

Usage

Installing
add flutter_video_compress as a dependency in your pubspec.yaml file.

dependencies:
  flutter_video_compress: ^0.3.x

Creating instance.

final _flutterVideoCompress = FlutterVideoCompress();

Get thumbnail by video file

final uint8list = await _flutterVideoCompress.getThumbnail(
  file.path,
  quality: 50,
);

Get thumbnail file by video file

final thumbnailFile = await _flutterVideoCompress.getThumbnailWithFile(
  file.path,
  quality: 50,
);

Converts provided video to a gif.

final file = await _flutterVideoCompress.convertVideoToGif(
  videoFile.path,
  startTime: 0,
  duration: 5,
);
print(file.path);

Get media information

Currently only supports video

final info = await _flutterVideoCompress.getMediaInfo(file.path);
print(info.toJson());

Compression Video

Compatible with ios in Android and web after compression

final info = await _flutterVideoCompress.compressVideo(
  file.path,
  deleteOrigin: true,
);
print(info.toJson());

Check Compressing state

_flutterVideoCompress.isCompressing

Stop compression

Android will print InterruptedException, but does not affect the use

await _flutterVideoCompress.cancelCompression()

delete all cache file

Delete all the files generated by this plugin, I think you ought to know what you are doing.

await _flutterVideoCompress.deleteAllCache()

Subscribe the conversion progress steam

class ... extends State<MyApp> {
  Subscription _subscription;

  @override
  void initState() {
    super.initState();
    _subscription =
        _flutterVideoCompress.compressProgress$.subscribe((progress) {
      print('progress: $progress');
    });
  }

  @override
  void dispose() {
    super.dispose();
    _subscription.unsubscribe();
  }
}

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:

  • exclude x86 related files (./assets)

  • This library does not use ffprobe, only usesffmpeg, but the application still has ffprobe, so it needs to be excluded (asssets/arm or assets/x86)

add this config in build.gradle:

  • Do not use ignoreAssetsPattern "!x86" in debug mode, will crash on the simulator
android {
 ...
   
   // Reduce your application size with this configuration
  aaptOptions {
       ignoreAssetsPattern "!x86:!*ffprobe"
  }
  
  buildTypes {
  ...
  
  }
