Parameters

format
DirectXPixelFormat

A value from the DirectXPixelFormat enumeration, specifying the pixel format of the created VideoFrame. Not all pixel formats are supported. See the Remarks section for more information.

width
Int32

int

The width, in pixels, of the created VideoFrame.

height
Int32

int

The height, in pixels, of the created VideoFrame.

Returns

A VideoFrame.

Attributes

Windows requirements

Device family
Windows 10, version 1803 (introduced in 10.0.17134.0)
API contract
Windows.Foundation.UniversalApiContract (introduced in v6.0)

Remarks

The following pixel formats, defined in the DirectXPixelFormat enumeration, are supported by VideoFrame.

  • DirectXPixelFormat_R16G16B16A16UIntNormalized
  • DirectXPixelFormat_R8G8B8A8UIntNormalized
  • DirectXPixelFormat_B8G8R8X8UIntNormalized
  • DirectXPixelFormat_B8G8R8A8UIntNormalized
  • DirectXPixelFormat_NV12
  • DirectXPixelFormat_P010
  • DirectXPixelFormat_Yuy2
  • DirectXPixelFormat_R16UIntNormalized
  • DirectXPixelFormat_R8UIntNormalized

All other formats are unsupported. Attempting to create a VideoFrame with an unsupported format will cause the method to fail with a COM exception.

The overload of this method, CreateAsDirect3D11SurfaceBacked, allows you to supply the IDirect3DDevice that is used to allocate the backing surface of the video frame.
