VideoHelper is a utility package for handling video processing in Flutter projects. powered by `ffmpeg_kit_flutter_full_gpl` package to easily execute video processing operations such as cropping, scaling, adjusting frame rates, setting bitrates, and more.

## Usage

Create a VideoHelper instance and use method chaining to process videos

```dart

// Initialize VideoHelper with the video file path

VideoHelper VideoHelper = VideoHelper(input: '/video_file.mp4');

// Set the output path

VideoHelper.setOutputPath('/processed_video_directory');

// Set the start and end time of the video

VideoHelper.setVideoSliceTime(startPoint: Duration(seconds: 0), endPoint: Duration(seconds: 10));

// Set the video scale

VideoHelper.setVideoScale(1280, 720);

// Set the video frame rate

VideoHelper.setVideoFrameRate(30);

// Set the video bitrate

VideoHelper.setVideoBitRate(2000);

// Set the video codec

VideoHelper.setVideoCodec('h264');

// Set the video quality

VideoHelper.setVideoCrf(20);

// Set the video filename

VideoHelper.setVideoFilename('processed_video_file_name.mp4');

// Set the video output format (optional)

VideoHelper.setVideoFormat('mp4');

// Disable video

VideoHelper.setDisableVideo();

// Disable audio

VideoHelper.setDisableAudio();

// Execute the FFmpeg command asynchronously

await VideoHelper.execAsync(

  completeCallback: (session) {

    print('Processing completed!');

    // Callback function after processing is completed

  },

  logCallback: (log) {

    print('FFmpeg log: $log');

    // Callback function for FFmpeg logs

  },

  statisticsCallback: (statistics) {

    print('FFmpeg statistics: $statistics');

    // Callback function for FFmpeg statistics

  },

);

// Get the media information of the video file

MediaInformation? mediaInfo = await VideoHelper.getMediaInfo();

// Output the media information of the video file

if (mediaInfo != null) {

  print('Video duration: ${mediaInfo.getDuration()}');

  print('Video resolution: ${mediaInfo.getStreams()[0].getWidth()}x${mediaInfo.getStreams()[0].getHeight()}');

}

```

chaining to process videos👇

```dart

VideoHelper(input: 'video_file.mp4')

  ..setOutputPath('processed_video_directory') // set target directory

  ..setVideoFilename('processed_video_file_name.mp4') // set video name

  ..setVideoSliceTime( // slice

    startPoint: const Duration(seconds: 20),

    endPoint: const Duration(seconds: 30),

  )

  ..setDisableAudio(); // disabled audio

```
