| NvMediaJPHuffmanTableSpecfication* NvMediaJPEncAttributes::chromaDC |
A Huffmann table for Chroma DC sample, initialized to NULL for using default table in JPEG specification.
The corresponding attribute mask is NVMEDIA_IMAGE_JPEG_ATTRIBUTE_HUFFTABLE Only support in T210 or greater
Definition at line 148 of file nvmedia_ijpe.h.
| uint8_t NvMediaJPEncAttributes::chromaQuant[64] |
A table for Chroma quantization, initialized to default standard table at NvMediaIJPE creation.
The corresponding attribute mask is NVMEDIA_IMAGE_JPEG_ATTRIBUTE_QUANTTABLE
Definition at line 130 of file nvmedia_ijpe.h.
| NvMediaJPHuffmanTableSpecfication* NvMediaJPEncAttributes::lumaAC |
A Huffmann table for Luma AC sample, initialized to NULL for using default table in JPEG specification.
The corresponding attribute mask is NVMEDIA_IMAGE_JPEG_ATTRIBUTE_HUFFTABLE Only support in T210 or greater
Definition at line 142 of file nvmedia_ijpe.h.
| NvMediaJPHuffmanTableSpecfication* NvMediaJPEncAttributes::lumaDC |

| uint8_t NvMediaJPEncAttributes::lumaQuant[64] |
A table for Luma quantization, initialized to default standard table at NvMediaIJPE creation.
The corresponding attribute mask is NVMEDIA_IMAGE_JPEG_ATTRIBUTE_QUANTTABLE
Definition at line 126 of file nvmedia_ijpe.h.
| uint8_t NvMediaJPEncAttributes::quality |
A value clamped to between 1 and 100, set to generate luma/chroma Quant tables.
It is initialized to 0 at NvMediaIJPE creation, so encoder will use default standard Luma/Chroma quant tables. The corresponding attribute mask is NVMEDIA_IMAGE_JPEG_ATTRIBUTE_QUALITY
