    Limit cyclic refresh on steady background blocks. · 3f7656cc
    Marco authored
    Use the existing QP condition on limiting cyclic refresh, and add
    addiitonal condition that block has been encoded with zero/small motion
    x frames in row (where x is at least several times the refresh period).
    Additional condition only affect non-screen content mode.
    
    This helps to improve visual stability for noisy input, where on steady
    background areas the application of delta_qp may lead to encoding the noise.
    
    Also added a change to use the true skip (after encoding) to update the
    last QP.
