Constructors
VideoFrame(BitmapPixelFormat, Int32, Int32, BitmapAlphaMode) |
Initializes a new instance of the VideoFrame class. |
VideoFrame(BitmapPixelFormat, Int32, Int32) |
Initializes a new instance of the VideoFrame class. |
Properties
Direct3DSurface |
Gets the IDirect3DSurface object containing the pixel data of the video frame, when one is present. |
Duration |
Gets or sets the duration of the video frame. |
ExtendedProperties |
Gets the extended property set which enables getting and setting properties on the media frame. |
IsDiscontinuous |
Gets or sets a value that indicates whether an video frame is the first frame after a gap in the stream. |
IsReadOnly |
Gets a value indicating whether the video frame is read-only. |
RelativeTime |
Gets or sets the relative time of the frame within the video stream. |
SoftwareBitmap |
Gets the SoftwareBitmap object containing the pixel data of the video frame, when one is present. |
SystemRelativeTime |
Gets or sets a timestamp that is relative to the system and is correlatable across multiple media sources on the same device. |
Type |
Gets a string indicating the type of video data the video frame contains. |
Methods
Close() |
Disposes of the object and associated resources. |
CopyToAsync(VideoFrame, IReference<BitmapBounds>, IReference<BitmapBounds>) |
Copies the specified rectangle in the current VideoFrame into the specified rectangle of a provided VideoFrame object. |
CopyToAsync(VideoFrame) |
Copies the current VideoFrame into a provided VideoFrame object. |
CreateAsDirect3D11SurfaceBacked(DirectXPixelFormat, Int32, Int32, IDirect3DDevice) |
Creates a new instance of the VideoFrame class for which the image data is stored in an IDXGISurface allocated by the supplied Direct3D device. |
CreateAsDirect3D11SurfaceBacked(DirectXPixelFormat, Int32, Int32) |
Creates a new instance of the VideoFrame class for which the image data is stored in an IDXGISurface allocated by the default Direct3D device. |
CreateWithDirect3D11Surface(IDirect3DSurface) |
Creates a new instance of the VideoFrame class for which the image data is stored in the provided IDXGISurface. |
CreateWithSoftwareBitmap(SoftwareBitmap) |
Creates a new instance of the VideoFrame class from the provided SoftwareBitmap. |
Dispose() |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. |
