-
-        Parameters
-        ----------
-        data : unicode, str or bytes
-            The raw image data or a URL or filename to load the data from.
-            This always results in embedded image data.
-
-        url : unicode
-            A URL to download the data from. If you specify `url=`,
-            the image data will not be embedded unless you also specify `embed=True`.
-
-        filename : unicode
-            Path to a local file to load the data from.
-            Images from a file are always embedded.
-
-        format : unicode
-            The format of the image data (png/jpeg/jpg/gif). If a filename or URL is given
-            for format will be inferred from the filename extension.
-
-        embed : bool
-            Should the image data be embedded using a data URI (True) or be
-            loaded using an <img> tag. Set this to True if you want the image
-            to be viewable later with no internet connection in the notebook.
-
-            Default is `True`, unless the keyword argument `url` is set, then
-            default value is `False`.
-
-            Note that QtConsole is not able to display images if `embed` is set to `False`
-
-        width : int
-            Width in pixels to which to constrain the image in html
-
-        height : int
-            Height in pixels to which to constrain the image in html
-
-        retina : bool
-            Automatically set the width and height to half of the measured
-            width and height.
-            This only works for embedded images because it reads the width/height
-            from image data.
-            For non-embedded images, you can just set the desired display width
-            and height directly.
-
-        unconfined : bool
-            Set unconfined=True to disable max-width confinement of the image.
-
-        metadata : dict
-            Specify extra metadata to attach to the image.
-
-        alt : unicode
-            Alternative text for the image, for use by screen readers.
-
-        Examples
-        --------
-        embedded image data, works in qtconsole and notebook
-        when passed positionally, the first arg can be any of raw image data,
-        a URL, or a filename from which to load image data.
-        The result is always embedding image data for inline images.
-

-
-        When this object is returned by an input cell or passed to the
-        display function, it will result in the video being displayed
-        in the frontend.
-
-        Parameters
-        ----------
-        data : unicode, str or bytes
-            The raw video data or a URL or filename to load the data from.
-            Raw data will require passing ``embed=True``.
-
-        url : unicode
-            A URL for the video. If you specify ``url=``,
-            the image data will not be embedded.
-
-        filename : unicode
-            Path to a local file containing the video.
-            Will be interpreted as a local URL unless ``embed=True``.
-
-        embed : bool
-            Should the video be embedded using a data URI (True) or be
-            loaded using a <video> tag (False).
-
-            Since videos are large, embedding them should be avoided, if possible.
-            You must confirm embedding as your intention by passing ``embed=True``.
-
-            Local files can be displayed with URLs without embedding the content, via::
-
-                Video('./video.mp4')
-
-        mimetype : unicode
-            Specify the mimetype for embedded videos.
-            Default will be guessed from file extension, if available.
-
-        width : int
-            Width in pixels to which to constrain the video in HTML.
-            If not supplied, defaults to the width of the video.
-
-        height : int
-            Height in pixels to which to constrain the video in html.
-            If not supplied, defaults to the height of the video.
-
-        html_attributes : str
-            Attributes for the HTML ``<video>`` block.
-            Default: ``"controls"`` to get video controls.
-            Other examples: ``"controls muted"`` for muted video with controls,
-            ``"loop autoplay"`` for looping autoplaying video without controls.
