2
3The **MovingPhotoView** component is used to play moving photos and control the playback status.
4
5> **NOTE**
6>
7> - This component is supported since API version 12. Updates will be marked with a superscript to indicate their earliest API version.
8> - Currently, the **MovingPhotoView** component cannot be used in Previewer.
9
10## Modules to Import
11
12```
13import { MovingPhotoView, MovingPhotoViewController, MovingPhotoViewAttribute } from '@kit.MediaLibraryKit';
14```
15
16## MovingPhotoView
17
18> **NOTE**
19>
20> - Currently, live attributes cannot be set.
21> - Currently, **expandSafeArea** in the ArkUI common attribute **ComponentOptions** cannot be set.
22> - When this component is long pressed to trigger playback, the component area is zoomed in to 1.1 times.
23> - This component uses [AVPlayer](../apis-media-kit/_a_v_player.md#avplayer) to play moving photos. A maximum of three [AVPlayers](../apis-media-kit/_a_v_player.md#avplayer) can be used at the same time. Otherwise, frame freezing may occur during the playback.
