Compressed video generates a new path with flutter

flutter_video_compress

Compressed video generates a new path, keep the source video or delete it. provide get video information or get thumbnail of the video file.

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 {
  ...
  
  }
