I'm developing an ionic app, where user can record a new video. Then I want to break the video into frames and send frames to a server. I'm using createThumbnail function from ionic-native VideoEditor plugin. But when I try to call createThumbnail function, it throws

ERROR Error: Uncaught (in promise): TypeError: Object(...) is not a function

ERROR Error: Uncaught (in promise): TypeError: Object(...) is not a function

这是我的源代码.

<ion-content padding>
  <button ion-button full (click)="captureVideo()">Capture video</button>
  <br/>
  <ion-list>
    <ion-item *ngFor="let file of mediaFiles" tappable (click)="playFile(file)" text-wrap>
      {{file.name}}
      <p>{{file.size/1000/1000 | number}} MB</p>
    </ion-item>
  </ion-list>
  <video controls autoplay #myvideo></video>
</ion-content>

打字稿代码

captureVideo() {
    let options: CaptureVideoOptions = {
      limit: 1,
      duration: 30
    }
    this.mediaCapture.captureVideo(options).then((res: MediaFile[]) => {

      let videoData = JSON.stringify(res);
      let res1 = JSON.parse(videoData);
      this.videoURL = res1[0]['fullPath'];
      
      let video = this.myvideo.nativeElement;
      video.src =  this.videoURL;
      video.play();

      var option: CreateThumbnailOptions = {
        fileUri: res[0].fullPath,
        outputFileName: 'aaaa',
        atTime: 2,
        width: 320,
        height: 480,
        quality: 100
      };
      console.log("option :" ,option);
      this.videoEditor.createThumbnail(option).then(res=>{
        console.log('Thumbnail result: ' + res);
      }).catch(err=>{
        console.log("ERROR ERROR", err)
      });

    }, (err) => {
      console.log("ERROR", "error selecting video");
    });
  }
