JPEG quantization tables are used to determine DCT compression for YUV data, as an alternative to specifying Q factor, providing exact control of compression
STRUCT MEMBERS: nSize : Size of the structure in bytes nVersion : OMX specification version information nPortIndex : Port that this structure applies to eQuantizationTable : Quantization table type nQuantizationMatrix[64] : JPEG quantization table of coefficients stored in increasing columns then by rows of data (i.e. row 1, ... row 8). Quantization values are in the range 0-255 and stored in linear order (i.e. the component will zig-zag the quantization table data if required internally)
