HarmonyOS 鸿蒙Next系统是否支持从视频中分离音频的API？或有推荐的三方API吗？

import { ICallBack, MP4Parser } from "@ohos/mp4parser";
import { promptAction } from "@kit.ArkUI";
import axios from "@ohos/axios";
import fs from '@ohos.file.fs';

@Component
export struct Mp4parserAudio {
  build() {
    Flex() {
      Button("下载mp4").onClick((event: ClickEvent) => {
        let exist = fs.accessSync(`${getContext().cacheDir}/3.mp4`);
        if (exist) {
          promptAction.showToast({
            message: "文件已存在"
          })
          return
        }
        axios.request({
          url: 'http://localhost:3000/download',
          method: 'GET',
          filePath: `${getContext().cacheDir}/3.mp4`
        }).then(() => {
          promptAction.showToast({
            message: "下载完成"
          })
        })
      })
      Button("执行ffmpeg方法").onClick((event: ClickEvent) => {
        let context = getContext()
        let cacheDir = context.cacheDir;
        let sourceMP4 = `${cacheDir}/3.mp4`;
        let outAudio = `${cacheDir}/output.aac`;
        let callBack: ICallBack = {
          callBackResult(code: number) {
            promptAction.showToast({ message: `${code}` })
          }
        }
        // ffmpeg -i input.mp4 -vn -c:a copy output.aac
        MP4Parser.ffmpegCmd(`ffmpeg -i ${sourceMP4} -vn -c:a copy ${outAudio}`,
          callBack)
      })
    }
  }
}
