    Use fast HEX search in real time mode · 360c80cf

    In good quality mode motion search, the best matches are normally
    found after searching in a large area. In real time mode, to make
    encoding fast, a center-biased fast HEX search is used, which
    converges quickly most of the time. A 4-point diamond search is
    also carried out as the following refining search, which gives more
    precise results, and maintains good motion search quality.
    At speed 5, the borg test on rtc set showed an overall PSNR loss of
    0.936%. The encoding speed gain is 4% - 5%.
