rfx_default_quantization_values

const UINT32 rfx_default_quantization_values[] = { 6, 6, 6, 6, 7, 7, 8, 8, 8, 9 }

static

The quantization values control the compression rate and quality. The value range is between 6 and 15. The higher value, the higher compression rate and lower quality.

This is the default values being use by the MS RDP server, and we will also use it as our default values for the encoder. It can be overrided by setting the context->num_quants and context->quants member.

The order of the values are: LL3, LH3, HL3, HH3, LH2, HL2, HH2, LH1, HL1, HH1
