HarmonyOS 鸿蒙Next录制视频功能实现，通过设备传入图片生成视频

您之前提过此类的单子，目前没有完整demo，您可以走赋能套件提需求。或者看看是否可以使用帧动画组件来实现您的需求，请参考以下文档：

示例代码：

// xxx.ets

[@Entry](/user/Entry)
[@Component](/user/Component)
struct ImageAnimatorExample {
  [@State](/user/State) state: AnimationStatus = AnimationStatus.Initial
  [@State](/user/State) reverse: boolean = false
  [@State](/user/State) iterations: number = 1
  build() {
    Column({ space: 10 }) {
      ImageAnimator()
        .images([
          {
            src: $r('app.media.test1'),
            duration:1500//单位毫秒
          },
          {
            src: $r('app.media.test2'),
            duration:1000
          },
          {
