Description

For 8bit photos the codec works. For 10bit it doesn't work anymore. What function is invariant for 10bit.

  if (!m_lmcsEnabled && m_sampleRange == 1 && m_matrixCoefficients == 0 && m_useColorTrans && m_iQP == 0)
  {
    if (m_costMode == COST_STANDARD_LOSSY || m_costMode == COST_MIXED_LOSSLESS_LOSSY_CODING)
    {
      msg( VERBOSE, "NearbyLossless < ");
    }
    if (m_costMode == COST_LOSSLESS_CODING)
    {
      msg( VERBOSE, "Lossless < ");
    }
  }

I didn't know that for a 10bit or more m_iQP isn't equal to zero. m_iQP is always close to zero. I wonder why this is so?
