pub(super) const INTEL_LOW_POWER_MIN_QP: u32 = 10;Expand description
The finest quantizer Intel’s low-power HEVC encoder codes: the driver clips the slice’s to 10..51 when it programs VDENC and looks its rate tables up from 10, and its rate control floors its own minimum at 10. A slice naming a finer one is coded at this one regardless, so the decoder dequantizes it too fine and the picture comes out washed out, the more so the finer the slice names (31 dB at 9 and 16 dB at 2 against 59 dB at 10, Arc A750).
