How to compress a video in flutter? I'm using image_picker to pick video from gallery which compress the video from 30MB to 10MB on iOS but in android there is no compression. Is there a way to manipulate the size or quality of video using dart? Are there any existing packages in flutter to compress video?

推荐答案

更新:由于我的原始答案(如评论中所指出)，因此还有另一个包

Update: since my original answer (as pointed out in the comment), there's another package https://pub.dev/packages/flutter_video_compress with friendlier API

在另一个类似问题中看到我的答案:

See my answer in another similar question:

https://pub.dartlang.org/packages/flutter_ffmpeg 很好，并有详细记录的说明

https://pub.dartlang.org/packages/flutter_ffmpeg is pretty good, and has well-documented instruction

import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';

 final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();

 _flutterFFmpeg.execute("-i file1.mp4 -c:v mpeg4 file2.mp4").then((rc) => print("FFmpeg process exited with rc $rc"));

检查 rc 代码，如果成功，则打开 file2.mp4 ，它是压缩/处理后的文件.

Check the rc code, and if it's successful, open file2.mp4, which is the compressed/processed file.
