      fixed a bug of context overwritten by key frame recoding · ea43ba4a
      Yaowu Xu authored
      The recoding loop save and restore frame coding context for recodes.
      However in recoding of key frames, some of the coding context saved
      was stale from last encoded inter frame. The save/restore sometimes
      overwrites the re-inintialized coding context with saved context
      from last frame, resulting in encoder/decoder mismatch

      Changed MAX_PSNR to be consistent with internal stats · 8cf28d34
      Yaowu Xu authored
      The maximum psnr has a marginal impact on the overall output in high
      quality encodings, the change will make sure the psnr output to be
      consistent with encoder internal stats.

      This gives a modest gain on derf overall, although at low bitrates the
      cost is still too high, so this can be improved further.

      Changed how UV r/d estimates are done for Intra Modes · 6898e8b7
      Yaowu Xu authored
      The commit changed to compute UV intra RD estimates for 4x4 and 8x8
      separately to be used in mode decision for MB modes associated with
      the appropriate transform size respectively. Now finally after many
      other changes related 8x8 quantizer zbin boost and zbin_mode_boost,
      this change overall helps the HD(with 8x8) by around ~.13%.
      (avg .13%  glb .13% ssim .17%)
      
      The commit also has a few changes for eliminating compiler warnings.

      Initial refactoring of high_precision mv code. · 3e1cad9c
      Deb Mukherjee authored
      This is the first patch for refactoring of the code related to
      high-precision mv, so that 1/4 and 1/8 pel motion vectors can
      co-exist in the same bit-stream by use of a frame level flag.
      The current patch works fine for only use of 1/4th and
      only use of 1/8th pel mv, but there are some issues with the
      mode switching in between. Subsequent patches on this change Id
      will fix the remaining issues.
      
      Patch 2: Adds fixes to make sure that multiple mv precisions can
      co-exist in the bit-stream. Frame level switching has been tested
      to work correctly.
      
      Patch 3: Fixes lines exceeding 80 char
      
      Patch 4:
      http://www.corp.google.com/~debargha/vp8_results/enhinterp.html
      
      Results on derf after ssse3 bugfix, compared to everything
      enabled but the 8-tap, 1/8-subpel and 1/16-subpel uv. Overall the
      gains are about 3% now. Hopefully there are no more bugs lingering.
      Apparently the sse3 bug affected the quartel subpel results more than
      the eighth pel ones (which is understandabale because one bad predictor
      due to the bug, matters less if there are a lot more subpel options
      available as in the 1/8 subpel case).
      The results in the 4th column correspond to the current settings.
      The first two columns correspond to two settings of adaptive switching
      of the 1/4 or 1/8 subpel mode based on initial Q estimate. These
      do not work as good as just using 1/8 all the time yet.

      fixed a wrong intialization value · eb87b56e
      Yaowu Xu authored
      The "update" variable was used as a flag in coef_prob update dry run
      that tests if a frame should encodes update at all. The wrong init
      value forced the update happening always. fixing this has a minor
      improvement in low bit rate situation when 8x8 transform is allowed.
