/**
* SECTION:plugin-d3d11
*
* Microsoft Direct3D11 plugin.
*
* This plugin consists of various video filter, screen capture source,
* video sink, and video decoder elements.
*
* GstD3D11 plugin supports H.264/AVC, H.265/HEVC, VP8, VP9, H.262/MPEG-2 video,
* and AV1 codecs for decoding as well as hardware-accelerated video
* deinterlacing. Note that minimum required OS version for video decoder and
* deinterlacing elements is Windows 8.
*
* Plugin feature names of decoders:
* - d3d11h264dec
* - d3d11h265dec
* - d3d11vp8dec
* - d3d11vp9dec
* - d3d11mpeg2dec
* - d3d11av1dec
*
* Similar to the video decoder case, deinterlacing element would be registered
* only if its supported by hardware with the feature name `d3d11deinterlace`
*
* However, depending on the hardware it runs on, some elements might not be
* registered in case that underlying hardware doesn't support the feature.
* For a system with multiple Direct3D11 compatible hardwares (i.e., GPU),
* there can be multiple plugin features having the same role.
* The naming rule for the non-primary decoder element is
* `d3d11{codec}device{index}dec` where `index` is an arbitrary index number of
* hardware starting from 1.
*
* To get a list of all available elements, user can run
* ```sh
* gst-inspect-1.0.exe d3d11
* ```
*
