Members

get_Handle

A handle to OS shared memory containing the texture.

public HRESULT get_Handle(HANDLE * value)

You can open it with ID3D11Device1::OpenSharedResource1 and write your texture data to it. Do not close it yourself. The underlying texture will be closed by WebView2. Do not change the texture after calling ICoreWebView2TextureStream::PresentTexture before you can retrieve it again with GetAvailableTexture, or you the frame may not be rendered and the ICoreWebView2TextureStream ErrorReceived event will be raised.

get_Resource

Returns IUnknown type that could be query interface to IDXGIResource.

public HRESULT get_Resource(IUnknown ** value)

The caller can write incoming texture to it.

get_Timestamp

Gets timestamp of presenting texture.

public HRESULT get_Timestamp(UINT64 * value)

put_Timestamp

Sets timestamp of presenting texture.

public HRESULT put_Timestamp(UINT64 value)

value is video capture time with microseconds units. The value does not have to be exact captured time, but it should be increasing order because renderer (composition) ignores incoming video frame (texture) if its timestamp is equal or prior to the current compositing video frame. It also will be exposed to the JS with VideoFrame::timestamp. (https://docs.w3cub.com/dom/videoframe/timestamp.html).
