    Add encoder/decoder support to frame_sign_bias · 17af2748
    Zoe Liu authored
    Frame sign bias value will not be signaled in frame header. Instead,
    the sign bias of reference frames are derived from their corresponding
    frame offsets at both encoder and decoder.
    The tool of 'frame_sign_bias' is dependent of 'frame_marker'. Compared
    against baseline, the enabling of both tools obtains a small coding gain
    of -0.08 ~ -0.11% in BDRate over Google lowres/midres tests.
