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