      fixed new intra code for rectanglar blocks · 4747c6ed
      Yaowu Xu authored
      Also fixed two minor subtle boundary conditions in intra prediction
      code, and replaced memcpy/memset with vpx_ prefixed version.

      Use same intra prediction for all block size · 3d655805
      Yaowu Xu authored
      The commmit changed to use same intra prediction function for all
      block sizes.
      
      Some details on the changes:
      1. All directional modes except DC/TM/V/H now have built-in filtering
      for all pixels with filter taps either (1, 2, 1)/4 or (1, 1)/2.
      2. Above edge get automatic extended to double width (bw*2), which
      makes a lot of the prediciton mode computation simpler.
      3. Same intra prediction function is called with different size
      for i4x4_pred and all other larger size.
      
      Overall, the change helped keyframe only coding for both cif size
      and std-hd size test sets by .5% consistently on all encodings.
      For normal coding with single/auto key frame, the change now also
      is consistently net positive for all encodings. The overall gains
      is about .15% on std-hd set.

      Use foreach_transformed_block with tokenize_b · 5c24469c
      John Koleszar authored
      Updates the tokenizer to use the common block walker used by the
      detokenizer, to support non-4:2:0 and more than 3 planes.

      Fix mi_row argument to update_stats(). · 7c5eb6d5
      Ronald S. Bultje authored
      This doesn't change output, because the argument isn't actually used
      ATM. However, we should fix it for consistency.

      This is shorter than fully writing out all cases (52 vs. 84 LOC), and

      Immigrate tokenize_mb into tokenize_sb · 3ac3c469
      Jingning Han authored
      Unify the tokenize_ function and enable configurable block size for
      superblock 8x8. We are immigrating the functionalities of
      macroblock handles into superblock ones, and eventually will remove
      encode_mb and decode_mb. To be continued on detokenize_ module.

      Output changes slightly because of a minor bug in (at least) the sb32x16
      block2above tx16x16 tables that previously existed in vp9_blockd.c.

      Turning model based reverse update on for coefs · 040eeed9
      Deb Mukherjee authored
      Turns model based reverse updates on for coefficients in an
      effort to reduce the memory requirement for counters.
      
      With this patch the counters needed will be reduced by about
      75% since only 3 counts are needed instead of 12.
      
      The impact in performance is:
      derf300: -0.252%
      stdhd250: -0.046%
      
      However retraining should alleviate some of the drop in
      performance.

      Unify decode_sb for >16x16 in vp9_decodframe.c · d8a120c1
      John Koleszar authored
      First patch to make sb decoding based on the transform size. This patch
      is working for the sb modes, combining the parts of decode_mb that fit
      into this framework will come as a second patch.
