/**

* @see_also: GstVideoBox
*
* <refsect2>
* <para>
* This element crops video frames, meaning it can remove parts of the
* picture on the left, right, top or bottom of the picture and output
* a smaller picture than the input picture, with the unwanted parts at the
* border removed.
* </para>
* <para>
* The videocrop element is similar to the videobox element, but its main
* goal is to support a multitude of formats as efficiently as possible.
* Unlike videbox, it cannot add borders to the picture and unlike videbox
* it will always output images in exactly the same format as the input image.
* </para>
* <para>
* If there is nothing to crop, the element will operate in pass-through mode.
* </para>
* <para>
* Note that no special efforts are made to handle chroma-subsampled formats
* in the case of odd-valued cropping and compensate for sub-unit chroma plane
* shifts for such formats in the case where the "left" or "top" property is
* set to an odd number. This doesn't matter for most use cases, but it might
* matter for yours.
