8-bit per channel planar YUV 4:2:0 video resource format. This format is subsampled where each pixel has its own Y value,

the layout of the data within the resource is completely opaque to applications. Applications cannot use the CPU to map
the resource and then access the data within the resource. You cannot use shaders with this format. Because of this behavior,
legacy hardware that supports a non-NV12 4:2:0 layout (for example, YV12, and so on) can be used. Also, new hardware that has
a 4:2:0 implementation better than NV12 can be used when the application does not need the data to be in a standard layout.
Width and height must be even. Direct3D 11 staging resources and initData parameters for this format use
(rowPitch * (height + (height / 2))) bytes.
An app using the YUY 4:2:0 formats must map the luma (Y) plane separately from the chroma (UV) planes.
Developers do this by calling ID3D12Device::CreateShaderResourceView twice for the same texture and passing
in 1-channel and 2-channel formats. Passing in a 1-channel format compatible with the Y plane maps only the Y plane.
Passing in a 2-channel format compatible with the UV planes (together) maps only the U and V planes as a single resource view.

Most common YUV 4:2:2 video resource format. Valid view formats for this video resource format are DXGI_FORMAT_R8G8B8A8_UNORM
and DXGI_FORMAT_R8G8B8A8_UINT. For UAVs, an additional valid view format is DXGI_FORMAT_R32_UINT. By using DXGI_FORMAT_R32_UINT
for UAVs, you can both read and write as opposed to just write for DXGI_FORMAT_R8G8B8A8_UNORM and DXGI_FORMAT_R8G8B8A8_UINT.
Supported view types are SRV and UAV. One view provides a straightforward mapping of the entire surface. The mapping to the
view channel is Y0->R8, U0->G8, Y1->B8, and V0->A8.
A unique valid view format for this video resource format is DXGI_FORMAT_R8G8_B8G8_UNORM. With this view format,
the width of the view appears to be twice what the DXGI_FORMAT_R8G8B8A8_UNORM or DXGI_FORMAT_R8G8B8A8_UINT
view would be when hardware reconstructs RGBA automatically on read and before filtering.
This Direct3D hardware behavior is legacy and is likely not useful any more. With this view format,
the mapping to the view channel is Y0->R8, U0->G8[0], Y1->B8, and V0->G8[1].
