  • Revision 9f79259e54 : adapt the adjustment limit for rate correction factor in RTC mode Rate correcti

    13 novembre 2014, par Yaowu Xu

    adapt the adjustment limit for rate correction factor in RTC mode

    Rate correction factor is used to correct the estimated rate for any
    given quantizer, and feeds into rate control for quantizer selection.
    We make use of the actual bits used to calculate this rate correction
    factor with an adjustment limit to prevent over-adjustment.

    This commit adapts the adjustment limit to the difference between the
    estimated bits and the actual bits, allows the adjustment limit to vary
    between 0.125 (when estimate is close to actual) and 0.625 (when there
    is >10X factor off between estimated and actual bits). By doing this,
    the commit appears to have largely corrected two observed issues :
    1. Adjustment is too slow when the actual bits used is way off from
    estimate due to the small adjustment limit.
    2. Extreme oscillating quantizer choices due to the feedback loop.

    avcodec/vc1 : fix mquant calculation

    In vc1_decode_i_blocks_adv mquant needs to be reset to its default value for
    
each macroblock, instead of once at the beginning of the slice.
    

    DQPROFILE specifies which macroblocks can have an alternative quantizer step
    
size. When DQPROFILE specifies edges, the selection is applicable to the edges
    
of the picture. Slice edges are not selected by DQPROFILE.

    vaapi_encode : Fix GOP sizing

    This change makes the configured GOP size be respected exactly -
    
previously the value could be exceeded slightly due to flaws in the
    
frame type selection logic.
