      High-bitdepth bugfixes · a160d725
      Deb Mukherjee authored
      Miscellaneous bug-fixes for high bitdepth functionality.
      With this patch, high bit-depth profiles become mostly functional,
      except for an intermittent assert failure issue that is being
      tracked.

      Modify block transform skipping check · e4aac6bb
      Yunqing Wang authored
      Block transform skipping was implemented based on DCT's energy
      conservation property. Modified the thresholds using zero bin
      parameters. AC and DC coefficients were checked separately to
      allow better identifying of skippable blocks.
      
      Borg test at speed 3 showed:
      stdhd set: psnr gain: 0.153%, ssim gain: 0.051%;
      derf set: psnr gain: 0.023%, ssim gain: 0.036%
      
      For most test clips, the encoding speedup is 1% - 2%.
      parkrun(720p): 7.5% speedup, park_joy(1080p): 3.5% speedup.

      Conditionally skip reference frame check · 891793a5
      Jingning Han authored
      For regular inter frames, if the distance from GOLDEN_FRAME is larger
      than 2 and if the predicted motion vector of LAST_FRAME gives lower
      sse than that of GOLDEN_FRAME, skip the GOLDE_FRAME mode checking in
      the rate-distortion optimization. It provides about 5% speed-up at
      expense of -0.137% and -0.230% performance down for speed 3. Local

      James Zern authored
      This reverts commit eafc8c9c.
      
      tran_low_t/tran_high_t don't belong in a public header, they're private.
      Similarly the public headers shouldn't rely on config defines,
      vpx_config.h isn't installed.

      Fix compiling error in vp9_idct.h · eafc8c9c
      Jingning Han authored
      This commit fixes a compiling error in vp9_idct.h, where the codec
      checks that the intermediate steps of transformation fit within
      16-bit length. The issue was due to broken file dependency.

      Fix a bug in calculating delta in VP9 denoiser. · 7ba646f7
      JackyChen authored
      When calculating delta in VP8 denoiser, since the block size is fixed to 16x16,
      the divisor is 256, which is the number of the pixel.
      But in VP9, the block size varies, the divisor should correspond to the block
      size.

      Adds two new subpel search methods · 4e9c0d2a
      Deb Mukherjee authored
      One is a more aggressive version of the pruned subpel tree
      search where only a single halfpel candidate is searched.
      The search candidate is based on a surface fit result.
      The other is a method to obtain the subpel position at one
      shot based on the same surface fit.
      
      The methods have not been deployed in any speed setting yet.

      Skip certain ALTREF inter modes in ARF coding · ccdb518f
      Jingning Han authored
      This commit enables the encoder to skip checking ALTREF inter modes
      in ARF coding, if the predicted motion vectors suggest that the
      GOLDEN_FRAME provides higher prediction accuracy than ALTREF_FRAME.
      
      It improves the speed 3 encoding speed by about 5%, at the expense
      of compression performance loss -0.041% and -0.225% for derf and
      stdhd, respectively.

      Skip the partition search for still frames · 1fcbf6ed
      Yunqing Wang authored
      This patch re-enabled the feature in Pengchong's patch
      (commit 12861260). Originally, it
      was turned on while use_lastframe_partitioning > 0(not used anymore).
      Now it was added as a feature, and turned on while speed >= 2.
      As described in the original patch, this feature helps speed up the
      slideshows in YouTube.
