  • Revision 1092140379 : No longer use use_lastframe_partitioning speed feature The speedup in rd_pick_p

    6 septembre 2014, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_speed_features.c



    No longer use use_lastframe_partitioning speed feature

    The speedup in rd_pick_partition() function makes it possible
    to drop use_lastframe_partitioning feature. By doing that, we
    achieve good PSNR gain with small speed loss. Also, this makes
    encoding loop less complicated. The code cleanup patch will
    follow.

    Borg tests showed :
    1. At speed 2,
    stdhd set : 0.201% PSNR gain, 0.133% SSIM gain ;
    derf set : 0.262% PSNR gain, 0.276% SSIM gain.
    2. At speed 3,
    stdhd set : 0.139% PSNR gain, 0.109% SSIM gain ;
    derf set : 0.447% PSNR gain, 0.442% SSIM gain.

    The average speed loss over selected test clips is within 1%
    with the worst case of 4%.

    Speed up compound inter prediction mode check

    This commit allows the encoder to store outcomes of single reference
    frame modes and compares them to decide if the inter prediction
    filter, forward transform, and quantization can be skipped.

    The compression performance of speed 3 is down
    derf -0.364%
    stdhd -0.198%

    For test sequences, the speed 3 runtime is reduced
    highway CIF 100 kbps, 51976 ms -> 45033 ms, 13% speed-up
    stockholm 720p 1000 kbps, 71826 ms -> 67838 ms, 5.5% speed-up
    pedestrian 1080p 2000 kbps, 154924 ms -> 150702 ms, 2.6% speed-up
