      Moving segmentation related vars into separate struct. · c4ad3273
      Dmitry Kovalev authored
      Adding segmentation struct to vp9_seg_common.h. Struct members are from
      macroblockd and VP9Common structs. Moving segmentation related constants
      and enums to vp9_seg_common.h.

      Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps
      goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is
      x86-64 only, it needs some minor modifications to be 32bit compatible,
      because it uses 15 xmm registers, whereas 32bit only has 8.

      Fix partition coding of corner block · 551f37d6
      Jingning Han authored
      This commit fixed the allowable partition types for bottom-right
      corner blocks.
      
      When a block has over half of its pixels as valid content in both
      vertical and horizontal directions, allow all the four partition
      types in the bit-stream. Otherwise, apply partition type constraints.

      The partition types of blocks sitting on the frame boundary are
      constrained by the block size and the position of each sub-block

      New intra mode and partitioning probabilities. · ad343687
      Ronald S. Bultje authored
      Split partition probabilities between keyframes and non-keyframes,
      since they are fairly different. Also have per-blocksize interframe
      y intramode probabilities, since these vary heavily between different
      blocksizes.
      
      Lastly, replace default probabilities for partitioning and intra modes
      with new ones generated from current codec. Replace counts with actual
      probabilities also.

      Initial version of alpha channel support · 679e4abd
      John Koleszar authored
      This is a mostly-working implementation of an extra channel in the
      bitstream. Configure with --enable-alpha to test. Notable TODOs:
      
       - Add extra channel to all mismatch tests, PSNR, SSIM, etc
       - Configurable subsampling
       - Variable number of planes (currently always uses all 4)
       - Loop filtering
       - Per-plane lossless quantizer
       - ARNR support
      
      This implementation just uses the same contents as the Y channel
      for the A channel, due to lack of content and general pain in
      playing back 4 channel content. A later patch will use the actual
      alpha channel passed in from outside the codec.
