      Always recode SUPERTX blocks. · f33755ef
      Geza Lore authored
      There is still an assertion failure when tokenizing transform
      coefficients for a supertx block, due to the eob not being set
      consistently with the coefficients, so we always recode supertx blocks
      for now. Also added further PICK_MODE_CONTEXT instances to avoid
      potential clash between horizontal/vertical/split partition SUPERTX
      trials.

      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.

      vp10: skip unreachable cat6 token extrabits. · 3461e8ce
      Ronald S. Bultje authored
      We have historically added new bits to cat6 whenever we added a new
      transform size (or bitdepth, for that matter). However, we have
      always coded these new bits regardless of the actual transform size,
      which means that for smaller transforms, we code bits that cannot
      possibly be set. The coding (quality) impact of this is negligible,
      but the bigger issue is that this allows creating bitstreams with
      coefficient values that are nonsensible and can cause int overflows,
      which then de facto become part of the bitstream spec. By not coding
      these bits, we remove this possibility.
      
      See issue 1065.

      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.
