Parameters

Parameter	Description
width	Width of the source image
height	Height of the source image
widthStride	Width of the source image after alignment
heightStride	Height of the source image after alignment
format	Image format. The default value is MXBASE_PIXEL_FORMAT_YUV_SEMIPLANAR_420. For details about the definition of the DVPP image format, see MxbasePixelFormat.
frameId	ID of an image frame
channelId	ID of an image channel
dataSize	Image data size, in bytes. The size must be the same as the actual image size. Otherwise, a core dump may occur.
outDataSize	Size of the output image data, in bytes. The value of outDataSize must be the same as that of the output image. Otherwise, a core dump may occur.
dataType	Image data type
data	Image data
outData	Address of the pre-allocated memory, which is used to store the image data after video decoding.
resizeWidth	Resizes the width during video decoding. Currently, only Atlas inference product support this parameter. The default value is 0, indicating that no resizing is performed. The value range is [10, 4096].
resizeHeight	Resizes the height during video decoding. Currently, only Atlas inference product support this parameter. The default value is 0, indicating that no resizing is performed. The value range is [6, 4096].
device	Device ID
deviceId	Device ID
destroy	Callback function for destroying the DVPP data
