 *
 *  1. This file declares the TUIVideoItem class, TUISnapshotItem class, and TUIVideoMessageCellData class.
 *    - TUIVideoItem corresponds to V2TIMVideoElem in the IM SDK. We convert the classes in the SDK to TUIVideoItem, which is convenient for us to further
 * process and operate the data.
 *    - TUISnapshotItem corresponds to the video cover class in the IM SDK. It is still an image in essence, but is bound to the corresponding Video.
 *    - TUIVideoMessageCellData inherits from the TUIMessageCellData class and is used to store a series of data and information required by the image message
 * unit.
 *  2. The business logic for obtaining video information and cover information has been implemented in this document. When you need to get video and cover
 * data, you can directly call the relevant member functions declared in this file
