Our D3D11/DXVA codecs implementation has been verified during 1.18 and 1.20 development cycle and also via the Fluster test framework. Similar to the case of nvdec and vtdec, we can prefer hardware over software in most cases Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1672>

/**

* 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
|
|
* ```
