  file.path,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Get thumbnail file from video path

final thumbnailFile = await _flutterVideoCompress.getThumbnailWithFile(
  file.path,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Convert video to a gif

final file = await _flutterVideoCompress.convertVideoToGif(
  videoFile.path,
  startTime: 0, // default(0)
  duration: 5, // default(-1)
  // endTime: -1 // default(-1)

final info = await _flutterVideoCompress.compressVideo(
  file.path,
  quality: VideoQuality.DefaultQuality, // default(VideoQuality.DefaultQuality)
  deleteOrigin: false, // default(false)
);
debugPrint(info.toJson().toString());

await _flutterVideoCompress.cancelCompression()

await _flutterVideoCompress.deleteAllCache()

Subscribe the compression progress steam

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

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

Notice

If your application is significantly larger after using the plugin, you can reduce the application size in the following way:

  • exclude x86 related files (./assets)

  • This library not use ffprobe, only used ffmpeg, but the application still has ffprobe, so you will need to exclude (asssets/arm or assets/x86)

add this config in build.gradle:

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

Questions

If your application is 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"
                }
            }
        }
    }
}

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

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

look detail

If your application never used a swift plugin before, maybe you would meet the error, you need to add the following code in ios/Podfile.

The ‘Pods-Runner’ target has transitive dependencies that include static binaries

pre_install do |installer|
  # workaround for https://github.com/CocoaPods/CocoaPods/issues/3289
  Pod::Installer::Xcode::TargetValidator.send(:define_method, :verify_no_static_framework_transitive_dependencies) {}
end

If the above method not work, you report bug of the error repository. The reason is「can’t support swift」

look detail

if show error of Regift

  • Regift does not specify a Swift version and none of the targets (Runner) integrating it have the SWIFT_VERSION attribute set. Please contact the author or set the SWIFT_VERSION attribute in at least one of the targets that integrate this pod.
pre_install do |installer|
  installer.analysis_result.specifications.each do |s|
      if s.name == 'Regift'
        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
