  • Revision 1e168d12d9 : Enable motion vector based prediction mode decision This commit enables vpxenc

    18 juillet 2014, par Jingning Han

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c



    Enable motion vector based prediction mode decision

    This commit enables vpxenc to compare the motion vector provided
    by external file to the predicted motion vectors and select the
    prediction mode with minimum rate cost if motion vector is matched.
    It doesn’t change reconstruction distortion, but provide rate
    savings.
