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, IOS and desktop (just MacOS for now).

Lets Get Started
1. Depend on it
Add this to your package's pubspec.yaml file:
dependencies:
video_compress: ^3.1.0
2. Install it
You can install packages from the command line:
with pub:
$ pub get
3. Import it
Now in your Dart code, you can use:
import 'package:video_compress/video_compress.dart';
How to use
Imports
import 'package:video_compress/video_compress.dart';
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();
}
}
TODO
- Add the trim video function
- Add cancel function to Android
