        """Set a new chat photo or video (H.264/MPEG-4 AVC video, max 5 seconds).

        The ``photo`` and ``video`` arguments are mutually exclusive.
        Pass either one as named argument (see examples below).

        You must be an administrator in the chat for this to work and must have the appropriate admin rights.

        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.

            photo (``str`` | ``BinaryIO``, *optional*):
                New chat photo. You can pass a :obj:`~pyrogram.types.Photo` file_id, a file path to upload a new photo
                from your local machine or a binary file-like object with its attribute
                ".name" set for in-memory uploads.

            video (``str`` | ``BinaryIO``, *optional*):
                New chat video. You can pass a :obj:`~pyrogram.types.Video` file_id, a file path to upload a new video
                from your local machine or a binary file-like object with its attribute
                ".name" set for in-memory uploads.

        Returns:
            ``bool``: True on success.

        Raises:
            ValueError: if a chat_id belongs to user.
