在Flutter中更新使用bytearray创建的MP3文件中的MetaData

dependencies:
  flutter_ffmpeg: ^0.4.0

import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';

void updateMetaData() async {
  final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();

  // 输入文件路径和输出文件路径
  String inputPath = "path/to/input.mp3";
  String outputPath = "path/to/output.mp3";

  // 更新MetaData的命令
  String command = "-i $inputPath -metadata title='New Title' -metadata artist='New Artist' -codec copy $outputPath";

  // 执行命令
  int result = await _flutterFFmpeg.execute(command);
  if (result == 0) {
    print("MetaData更新成功");
  } else {
    print("MetaData更新失败");
  }
}
