推荐答案

更新：由于我的原始回答，因此还有另一个软件包 https://pub.dev/packages/flutter_video_compress 使用更友好的API

Update: since my original answer, there's another package https://pub.dev/packages/flutter_video_compress with friendlier API

https://pub.dartlang.org/packages/flutter_ffmpeg 非常好，并且有详细记录的说明

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，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.
