Compress videos, remove audio, manipulate thumbnails, and make your video

September 12, 2020 Flutter App, Video

video_compress

Compress videos, remove audio, manipulate thumbnails, and make your video compatible with all platforms through this lightweight and efficient library. 100% native code was used, we do not use FFMPEG as it is very slow, bloated and the GNU license is an obstacle for commercial applications. In addition, google chrome uses VP8/VP9, safari uses h264, and most of the time, it is necessary to encode the video in two formats, but not with this library. All video files are encoded in an MP4 container with AAC audio that allows 100% compatibility with safari, mozila, chrome, android and iOS.

Works on ANDROID and IOS.

How to use

Video compression

MediaInfo mediaInfo = await VideoCompress.compressVideo(
  path,
  quality: VideoQuality.DefaultQuality, 
  deleteOrigin: false, // It's false by default
);

Check compress state

VideoQuality.isCompressing

Get memory thumbnail from VideoPath

final uint8list = await VideoCompress.getByteThumbnail(
  videopath,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Get File thumbnail from VideoPath

final thumbnailFile = await VideoCompress.getFileThumbnail(
  videopath,
  quality: 50, // default(100)
  position: -1 // default(-1)
);

Get media information

final info = await VideoCompress.getMediaInfo(videopath);

delete all cache files

Delete all files generated by this will delete all files located at ‘video_compress’, you shoule ought to know what are you doing.

await VideoCompress.deleteAllCache()

Listen the compression progress

class _Compress extends State<Compress> {

  Subscription _subscription;

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

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