接口
Video(value: {src?: string, currentProgressRate?: number | string, previewUri?: string, controller?: VideoController})

示例代码：

// @ts-nocheck
@Entry
@Component
struct VideoExample {

  @State autoPlay: boolean = false
  @State controls: boolean = true
  @State startStaus: boolean = true
  myVideoController: VideoController = new VideoController()

  build() {
    Column({ space: 10 }) {
