  • Revision 645b7cdf03 : move clear_system_state() call before using double Floating point is used in vp

    27 janvier 2015, par Yaowu Xu

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



    move clear_system_state() call before using double

    Floating point is used in vp9_convert_qindex_to_q(), so sometime unit
    test ActiveMapTest would cause run time error without properly call
    to clear_system_state to reset register status.
