    Skip intra mode tests depending on inter residuals · 4282955e
    Jingning Han authored
    This commit allows encoder to skip intra coding mode test, when
    the known inter residual is less than the source variance. It
    reduces the runtime of speed 3 for test clips:
    bus cif 1000 kbps: 8587 ms -> 8260 ms, 3.8% speed-up
    pedestrian 1080p 2000 kbps: 161381 ms -> 155241 ms, 3.7% speed-up.
    The compression performance is down by
    derf   -0.36%
    stdhd  -0.25%
