How To Make Video Fileupload In Angular 4?

I created a Java API to do fileupload from any file, it's something simple, it just takes any selected image and sends it to C: \ images, I'm using it with Angular 4, my goal is to do this with video, but I had tried before with images since they are easier to find available codes and ready with images implementation.

I did it with video and it did not work, I think it's something I should change in my Front-end Angular. Then see the code below;

This is my service;

export class MidiaService {

  midiasUrl = 'http://localhost:8080/midias';


  constructor(private http: Http) { }


  urlUploadAnexo(): string {
    return '${this.midiasUrl}/files';
}

And that's my component:

get urlUploadAnexo() {
    return this.midiaService.urlUploadAnexo();
}

And this is my page:

<div class="ui-g-6 ui-md-3 ui-fluid">
        <label>URL</label>
        <p-fileUpload name="files" mode="basic" auto="true" maxFileSize="1000000000000000000000000000"
        chooseLabel="Anexar" accept="image/*,application/*"
        [url]="urlUploadAnexo"
    ></p-fileUpload>
      </div>

I think the place where I should change to accept video files should be on the page, would anyone have a suggestion how should I make the change? please!
