* @title: d3d11convert
* @short_description: A Direct3D11 based color conversion and video resizing element
*
* This element resizes video frames and change color space.
* By default the element will try to negotiate to the same size on the source
* and sinkpad so that no scaling is needed.
* It is therefore safe to insert this element in a pipeline to
* get more robust behaviour without any cost if no scaling is needed.
*
* ## Example launch line
* ```
* gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12 ! d3d11upload ! d3d11convert ! d3d11videosink
* ```
* This will output a test video (generated in NV12 format) in a video
* window. If the video sink selected does not support NV12
* d3d11convert will automatically convert the video to a format understood
* by the video sink.
*
* Since: 1.18
