    Fixes for key frame coding at speed 5. · fb2a89b1
    Marco authored
    Keep the same transform cutoff and partition selection
    for speed 5 as in speeds >=6 (non-rd speed settings).
    Existing setting for key frame at speed 5 allowed transform size
    up to 32x32 on key frames, and did not allow for 4x4 block partition size.
    This created more visual artifacts on first few frames.
    avgPSNR/overallPSNR/SSIM gains of 0.2/0.7/0.8 for rtc_derf(low-res) set,
    and 0/0.7/1.1 gains for rtc set.
