      Super transform - ported from nextgen branch · 3787b174
      Debargha Mukherjee authored
      Various additional changes were made to make the experiment
      compatible with misc_fixes.
      
      derflr: +0.979%
      hevcmr: +0.865%
      
      Speed-wise with --enable-supertx the encoder is only about 10%
      slower than without. Decoding impact is about 30% slowdown.
      
      Note this does not work with ext-tx or var-tx yet. That is
      a TODO.

      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.

      Moving eob array to the encoder. · f00d157c
      Dmitry Kovalev authored
      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.
