HarmonyOS 在使用AVplayer中如何自定义播放视频的大小？

XComponent({ 
  id: 'video_player_id', 
  type: XComponentType.SURFACE, 
  controller: this.mXComponentController 
}) 
  .border({ width: 1, color: Color.Red }) 
  .onLoad(() => { 
    this.surfaceId = this.mXComponentController.getXComponentSurfaceId() 
    this.xComponentContext = this.mXComponentController.getXComponentContext() as Record<string, () => void> 
    let surfaceRect: SurfaceRect = { 
      offsetX: 200, 
      offsetY: 200, 
      surfaceWidth: 5000, 
      surfaceHeight: 1000 
    } 
    this.mXComponentController.setXComponentSurfaceRect(surfaceRect) 
    this.rect = this.mXComponentController.getXComponentSurfaceRect() 
    this.player = new AVPlayerDemo(); 
    this.player.setSurfaceID(this.mXComponentController.getXComponentSurfaceId()); 
    this.player_changed = !this.player_changed; 
    this.player.avPlayerLiveDemo() 
  }) 
  .onTouchIntercept((event: TouchEvent) => { 
    console.log("OnTouchIntercept + " + JSON.stringify(event)); 
    return HitTestMode.None 
  })
