Function Documentation

WSC_SubmitTexture()

WSCResult WSC_SubmitTexture	(	int	outputId,
		void *	d3d11Texture2D )

Submit a D3D11 texture directly (GPU→GPU, no CPU copy).

Parameters

outputId	Output ID.
d3d11Texture2D	Pointer to ID3D11Texture2D in BGRA format.

Returns

WSC_OK on success.

WSC_SubmitTextureNV12()

WSCResult WSC_SubmitTextureNV12	(	int	outputId,
		void *	d3d11Texture2D,
		int	subresourceIndex )

Submit an NV12 texture via D3D11 Video Processor.

Uses hardware color conversion (YUV→RGB), scaling, and ProcAmp (brightness/contrast/saturation/hue) on the GPU Copy/Video engine instead of the 3D pipeline. Shows as "GPU-Copy" in Task Manager.

Parameters

outputId	Output ID.
d3d11Texture2D	Pointer to ID3D11Texture2D in NV12 format.
subresourceIndex	Subresource index within texture array (e.g. from DXVA).

Returns

WSC_OK on success.

WSC_SubmitFrameNV12()

WSCResult WSC_SubmitFrameNV12	(	int	outputId,
		const void *	nv12Data,
		int	width,
		int	height,
		int	pitch )

Submit raw NV12 frame data from CPU memory.

Data layout: Y plane (height * pitch bytes) followed by UV plane ((height/2) * pitch bytes, interleaved U/V).

Parameters

outputId	Output ID.
nv12Data	Pointer to NV12 data (Y + UV planes).
width	Frame width in pixels.
height	Frame height in pixels.
pitch	Row stride in bytes (Y and UV share the same pitch).

Returns

WSC_OK on success.
