pSwapchainImages

pSwapchainImages is a property of the Direct3D 10 and 11 APIs that refers to an array of presentation targets for a swap chain. A swap chain is a set of resources used to render multiple frames of a 3D scene in parallel. This property is accessed through the ID3D11DeviceContext11 and ID3D11Device interfaces.

The pSwapchainImages property is an array of ID3D11RenderTargetView objects that represent the buffers in the swap chain where video data is stored. Each element in the array corresponds to a planned frame in the queue, where a frame is an array of pixels luminance sample values. The ID3D11RenderTargetView objects are the key to accessing the pixel data, allowing for the fetching of pixel data from the presented frame.

The pSwapchainImages property is provided to get the necessary buffer information for the current frame being presented by an ID3D11DeviceContext11 interface, such as the ID3D11DeviceContext11::GetDecoderBufferInfo or the ID3D11DeviceContext11::GetVideoDecoderBuffer method.

When accessed, the array returned by the pSwapchainImages property can give information about resources, specific frames in the swap chain, the frame that will be swapped out next, and the ID of the frame to present. A specified present-only flag can be set to render changes made to the current render target view. It is required when presenting the current frame cached in the corresponding swap chain.

It is used interchangeably with the GetSwap Chain Dependent Render Targets function combined with the Presentation-related Outputs which return required Buffered Render Target View List that inturn intercepts the result returned by pSwapchainImages to run the system and to stop it from dying to min-delaying resources
