      vp9_ethread: modify VP9_COMP structure · edbd61e1
      Yunqing Wang authored
      This patch modified struct VP9_COMP. Created a struct ThreadData
      to include data that need to be copied for each thread. In
      multiple thread case, one thread processes one tile. all threads
      share one copy of VP9_COMP,
      (refer to VP9_COMP *cpi in the code)
      but each thread has its own copy of ThreadData,
      (refer to ThreadData *td in the code).
      Therefore, within the scope of encode_tiles(), both cpi and td
      need to be passed as function parameters.
      
      In single thread case, the FRAME_COUNTS pointer in ThreadData
      points to "counts" in VP9_COMMON.

      Rework partition search skip scheme · bb260d90
      Jingning Han authored
      This commit enables the encoder to skip split partition search if
      the bigger block size has all non-zero quantized coefficients in low
      frequency area and the total rate cost is below a certain threshold.
      It logarithmatically scales the rate threshold according to the
      current block size. For speed 3, the compression performance loss:
      derf  -0.093%
      stdhd -0.066%
      
      Local experiments show 4% - 20% encoding speed-up for speed 3.

      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

      In the decoder we don't need to save eobs, we can pass eob as an argument.
      That's why removing eob arrays from VP9Decompressor and TileWorkerData,
      and moving eob pointer from macroblockd_plane to macroblock_plane.

      Using 128 entry look up table for coef models · de4d682c
      Deb Mukherjee authored
      Reverts to using 128 bit LUT for the coef models rather than 48
      to ease hardware implementation.
      
      Also incorporates some cleanups including removing various
      hooks to support different lookup tables based on block_type and
      ref_type.

      Updating the model coef experiment · 39a90bc8
      Deb Mukherjee authored
      Cleans up the experiment. Actually uses reduced counts for backward
      updates, and reduced number of probabilities in the context.
      
      No change in bitstream when the experiment is on.
      
      Between expt on and off:
      derfraw300 is down only -0.062% (which is better than when expts
      were run previously).

      This cleans out various other sub-experiments that were part
      of the origiinal patch, which will be later included if found
      useful.
      
      Results are slightly positive on all sets (0.1 - 0.2% range).

      Make SB coding size-independent. · a3874850
      Ronald S. Bultje authored
      Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
      gives identical encoder results before and after. There are a few
      macros for rectangular block sizes under the sbsegment experiment; this
      experiment is not yet functional and should not yet be used.

      Use above/left (instead of previous in scan-order) as token context. · 790fb132
      Ronald S. Bultje authored
      Pearson correlation for above or left is significantly higher than for
      previous-in-scan-order (absolute values depend on position in scan, but
      in general, we gain about 0.1-0.2 by using either above or left; using
      both basically just makes this even better). For eob branch skipping,
      we continue to use the previous token in scan order.
      
      This helps about 0.9% on derf after re-training on a limited data set.
      Full re-training and results on larger-resolution clips are pending.
      
      Note that this commit breaks trellis, so we can probably get further
      gains out of it by fixing trellis at some later point.

      Make superblocks independent of macroblock code and data. · 111ca421
      Ronald S. Bultje authored
      Split macroblock and superblock tokenization and detokenization
      functions and coefficient-related data structs so that the bitstream
      layout and related code of superblock coefficients looks less like it's
      a hack to fit macroblocks in superblocks.
      
      In addition, unify chroma transform size selection from luma transform
      size (i.e. always use the same size, as long as it fits the predictor);
      in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma
      transform will now use the 16x16 (instead of the 8x8) chroma transform,
      and 64x64 superblocks using the 32x32 luma transform will now use the
      32x32 (instead of the 16x16) chroma transform.
      
      Lastly, add a trellis optimize function for 32x32 transform blocks.
      
      HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's
      a few negative points here and there that I might want to analyze
      a little closer.
