Field Documentation

inFmt

Fvid2_Format Ldc_Config::inFmt

Input Frame format, describing input frames storage format Following parametes are used from this width = width of the input frame height = height of the input frame pitch = line offset for the input data, only pitch[0] is used for all dataformats For YUV420, pitch is common for both luma and chroma dataFormat = Input DataFormat sfcc = Storage format

enableOutput

UInt32 Ldc_Config::enableOutput[LDC_MAX_OUTPUT]

Flags to enable LDC Outputs Output[0] must be enabled Output[1] is optional 1: Enables the output 0: Disables the output

outFmt

Fvid2_Format Ldc_Config::outFmt[LDC_MAX_OUTPUT]

Output Frame format, describing output frames storage format

Following parametes are used from this pitch = line offset for the input data, used based on the data format dataFormat = Input DataFormat sfcc = Storage format

Frame size for all the outputs is same and is configured in outputFrameWidth and outputFrameHeight in common place

enableBackMapping

uint32_t Ldc_Config::enableBackMapping

Flag to enable/disable LDC Back Mapping 1: Enables LDC back mapping 0: Disables LDC Back mapping

lumaIntrType

uint32_t Ldc_Config::lumaIntrType

Luma Interpolation Type, Look into Ldc_LumaIntrType for valid values

perspTrnsformCfg

Ldc_PerspectiveTransformCfg Ldc_Config::perspTrnsformCfg

Affine transformation parameters

lutCfg

Ldc_LutCfg Ldc_Config::lutCfg

LDC Lut configuration

outputFrameWidth

uint32_t Ldc_Config::outputFrameWidth

Output Frame Width, could be different from input frame width

outputFrameHeight

uint32_t Ldc_Config::outputFrameHeight

Output Frame Height, could be different from input frame width

pixelPad

uint32_t Ldc_Config::pixelPad

Pixel pad

outputBlockWidth

uint32_t Ldc_Config::outputBlockWidth

Output block width must be multiple of 8 in 422/422 mode must be greater than or equal to 8

outputBlockHeight

uint32_t Ldc_Config::outputBlockHeight

Output block Height must be even and greater than 0

outputStartX

uint32_t Ldc_Config::outputStartX

Output starting X-coordinate (must be even and multiple of 8)

outputStartY

uint32_t Ldc_Config::outputStartY

Output starting Y-coordinate (must be even)

enableMultiRegions

uint32_t Ldc_Config::enableMultiRegions

Enable Multi Region Processing

regCfg

Ldc_RegionConfig Ldc_Config::regCfg

Region Configuration Used only when enableMultiRegions = TRUE Used to configure different block size and pixel pad for each region Output Width of all enabled regions in a vetical slice must be same Similarly Output Height of all enabled region in a horizontal slice must be same The sum of width of all enabled regions in a vertical slice must be equal or less than outputFrameWidth Similarly, The sum of height of all enabled regions in a horizontal slice must be equal or less than outputFrameHeight
