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>

TypeScript 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");
    });
  }

谁能帮帮我，为什么我会收到这样的错误?

推荐答案

似乎 ionic 团队对他们的原生插件做了一些更改.您需要安装与您的项目类型相对应的正确版本的原生插件.并根据您的角度版本正确导入.你需要做的就是，

It seems ionic team has made some changes to their native plugins. You need to install the correct version of the native plugin corresponding to your project type. And import it correctly based on your angular version. All you need to do is,

在 ionic.config.json 文件中检查您的项目类型.

Check your project type in ionic.config.json file.

如果类型是ionic-angular"，则安装 4.x.x 版本.你的情况

If the type is "ionic-angular", then install 4.x.x version. In your case

npm i -s @ionic-native/video-editor@4.20.0

如果类型为angular"，则安装5.x.x-beta版

If the type is "angular", then install 5.x.x-beta version

npm i -s @ionic-native/video-editor@5.0.0-beta.24

注意:

仅当您使用 Angular 6 时，才在导入结束时添加 ngx

Add ngx at the end of import only if you are using Angular 6

import { VideoEditor } from '@ionic-native/video-editor/ngx';

如果不从 app.module.ts 和 app.component.ts 中的导入中删除 ngx

if not remove ngx from the import both in app.module.ts and app.component.ts

import { VideoEditor } from '@ionic-native/video-editor';
