    1 pass VBR mode bug fix. · cea5e1c1
    paulwilkins authored
    The one pass VBR mode selects a Q range based on a
    moving average of recent Q values. This calculation
    should have been excluding arf overlay frames as these
    are usually coded at the highest allowed value. Their
    inclusion skews the average and can cause it to drift
    upwards even when the clip as a whole is undershooting.
    As such it can undermine correct adaptation of the allowed
    Q range especially for easy content.
