vpiCreateImageFFT()

VPIStatus vpiCreateImageFFT	(	VPIStream	stream,
		uint32_t	inputWidth,
		uint32_t	inputHeight,
		const VPIImageType	inType,
		const VPIImageType	outType,
		VPIPayload *	payload
	)

#include <vpi/algo/ImageFFT.h>

Creates payload for vpiSubmitImageFFT.

Parameters

stream	[in] a stream handle
inputWidth	[in] width of input image
inputHeight	[in] height of input image
inType	[in] input image type
outType	[in] output image type
payload	[out] pointer to a payload handle

Returns

an error code on failure else VPI_SUCCESS

vpiSubmitImageFFT()

VPIStatus vpiSubmitImageFFT	(	VPIPayload	payload,
		VPIImage	input,
		VPIImage	output,
		uint32_t	flags
	)

#include <vpi/algo/ImageFFT.h>

Runs FFT on single image.

Parameters

payload	[in] payload created with vpiSubmitImageFFT
input	[in] input image
output	[in] output image
flags	[in] control flags, currently it must be set to 0.

Returns

an error code on failure else VPI_SUCCESS
