点击资料库右上角的加号，通过系统“文件”选择器选择视频。IINV 默认保存文件引用，不会额外复制视频。
外部文件可能已被移动、删除，或者所在网盘暂时不可访问。请确认文件仍在原位置且已经下载到设备，然后重新添加。
长按视频并选择“保存离线”。IINV 会创建应用内副本，你可以随时移除该副本。
画中画需要受支持的真实设备和可播放的视频。模拟器可能不会提供完整的画中画能力。
请查看 IINV 隐私政策。IINV 不要求账户，也不会上传你的视频或播放记录。

Tap the plus button and choose a video with the system Files picker. IINV stores a file reference by default and does not create another copy.
The external file may have moved, been deleted, or become unavailable from its cloud provider. Confirm that the file is still present and downloaded, then add it again.
Touch and hold a video, then choose Save Offline. IINV creates an app-local copy that you can remove at any time.
Picture in Picture requires a supported physical device and playable media. The simulator may not expose the full capability.
Read the IINV Privacy Policy. IINV requires no account and does not upload videos or playback history.
