      Yunqing Wang authored
      Spatial/temporal svc code was removed. Verified using Borg test,
      and the results before and after the change are matching.

      Fix a setting in cyclic refresh. · dc36e5af
      Marco authored
      Use the correct period (in terms of cr->percent_refresh) for the condition
      of larger delta-qp following key frame.
      And account for larger interval for temporal layers.

      aq-mode=3: Reduce boost for segment#2 at low bitrates/low res. · 517a6620
      Marco authored
      Reduce boost for segment#2 for low bitrates and low-res.
      
      This change is to reduce the rate overshoot at low bitrates.
      No change in behavior, except at the very low bitrates.

      Limit cyclic refresh revisitng blocks at the same quantizer. · 90c9ede8
      Alex Converse authored
      For screen content don't refresh a block at a quantizer higher than
      it was last coded at. PReviosuly at realtime speeds the encoder had a
      tendency to recode a block from GOLDEN with a higher Q than it was last
      coded at.

      Add dynamic resize logic for 1 pass CBR. · d77f51ba
      Marco authored
      Decision to scale down/up is based on buffer state and average QP
      over previous time window. Limit the total amount of down-scaling
      to be at most one scale down for now.
      
      Reset certain quantities after resize (buffer level, cyclic refresh,
      rate correction factor).
      
      Feature is enable via the setting rc_resize_allowed = 1.

      Marco authored
      Reduce motion threshold and boost factor for second segment,
      for low bitrates, at low resolutions for now.
      This is to reduce the rate fluctuation/frame dropping that occurs

      Improve golden frame refreshing in non-rd mode · d31698b0
      Yunqing Wang authored
      The default golden frame interval was doubled. After encoding a
      frame, the background motion was measured. If the motion was high,
      the current frame was set as the golden frame. Currently, the
      changes were applied only while aq-mode 3 was on.
      
      Borg tests(rtc set) showed a 0.226% PSNR gain and 0.312% SSIM gain.
      No speed changes.

      Factor in segment#2 and skip blocks into the postencode estimated bits,

      Adjustments to cyclic refresh (aq-mode=3). · 0187f4b4
      Marco authored
      Target higher delta-qp for big blocks with zero motion,
      and for segment#1: avoid 64x64 partition size and force 8x8 tx size.
      
      Metrics on RTC set mostly positive: SSIM up by ~4%, PSRN by ~1.5%.
      Doesn't seem to be any change in speed.

      Add distortion threshold condition to refresh state of a coding block,

      vp9_ethread: modify the cyclic refresh struct · 8ee605f1
      Yunqing Wang authored
      Two members in struct CYCLIC_REFRESH
        int64_t projected_rate_sb;
        int64_t projected_dist_sb;
      are updated at the superblock level, which makes them shared data
      in the multi-thread situation, and requires extra work to handle
      them. However, those values are updated and used immediately, and
      therefore can be removed. This patch cleaned up the code and
      removed the two members.

      Rework cut-off decisions in cyclic refresh aq mode · caaf63b2
      Jingning Han authored
      This commit removes the cyclic aq mode dependency on
      in_static_area and reworks the corresponding cut-off thresholds.
      It improves the compression performance of speed -5 by 1.47% in
      PSNR and 2.07% in SSIM, and the compression performance of speed
      -6 by 3.10% in PSNR and 5.25% in SSIM. Speed wise, about 1% faster
      in both settings at high bit-rates.

      Split vp9_rdopt into vp9_rdopt and vp9_rd. · 03c276ea
      Alex Converse authored
      vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all
      other rd related routines. Anything used outside of making an rd optimal
      decision belongs in rd.

      Enable background detection for adaptive quantizer control · 80a4f559
      Jingning Han authored
      This commit enables a background detection approach for adaptive
      quantizer control. It combines the cyclic refresh pattern and the
      background information to determine the segment id for adaptive
      quantizer selection, prior to the non-RD mode decision process.
      It hence allows proper quantization information update for a more
      precise rate-distortion modeling in the non-RD mode decision.
      
      The compression performance of speed -5 for rtc set is improved
      by 2.5%, at no speed change.
