      vpx_dsp/bitreader.h: vp9_->vpx_ · bf82514b

      Replace vp9_ in names to vpx_ as they are not codec specific.

      Reduce dqcoeff array size in decoder · cccad1c5
      Jingning Han authored
      The decoding process handles detokenization and reconstruction per
      transform block sequentially. There is no need to offset the dqcoeff
      buffer according to the transform block index. This allows to
      reduce the memory spill and improve cache performance.

      Re-worked header files · b962646f
      Scott LaVarnway authored
      Various header/test files had to be re-worked in order to
      build "Remove cm parameter from vp9_decode_block_tokens()".
      
      This patch reverts the "Remove cm" part and only contains
      the re-worked header files.

      Revert "Remove mi_grid_* structures." · 8b17f7f4
      Scott LaVarnway authored
      (see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6)
      
      For the test clip used, the decoder performance improved by ~2%.
      This is also an intermediate step towards adding back the
      mode_info streams.

      vp9_dthread: pass frame counts to decoder functions · 85a9bc04
      Yunqing Wang authored
      The current multi-threaded tile decoder requires that the videoes
      are encoded with frame_parallel_decoding_mode = 1. This requirement
      is not necessary, and is better to be removed. This patch includes
      the first part of the work.

      vp9_ethread: allocate frame contexts outside VP9_COMMON struct · 7c7e4d4e
      Yunqing Wang authored
      This patch allocated frame contexts outside VP9_COMMON. This allows
      multiple threads to share the same copy of frame contexts, and
      reduces the overhead. It also guarantees the correct update of
      these contexts during bitstream packing. This patch doesn't change
      encoding result.

      Add range checking for decoded coefficients. · 9751aa12
      Yaowu Xu authored
      The coefficient range checking is enabled when configured with
      --enable-debug --enable-coefficient-range-checking
      for vpxdec to detect ill-formed input stream. This addresses the
      problem raised by issue #792.

      Remove mi_grid_* structures. · c70cea97
      hkuang authored
      mi_grid_* are arrays of pointer to pointer. They save the pointers that point
      to the MIs in cm->mi. But they are unnecessary and complicated. The original
      goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer
      inside MODE_INFO_t, same goal could be achieved.
      
      This commit totally removes the mi_grid_* structures. But there are still
      many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit
      will do on-demand MODE_INFO_t allocation in order to save these memories.

      Adds high bitdepth transform functions and tests · 10783d4f
      Deb Mukherjee authored
      Adds various high bitdepth transform functions and tests.
      Much of the changes are related to using typedefs tran_low_t
      and tran_high_t for the final transform cofficients and intermediate
      stages of the transform computation respectively rather than fixed
      types int16_t/int. When vp9_highbitdepth configure flag is off,
      these map tp int16_t/int32_t, but when the flag is on, they map
      to int32_t/int64_t to make space for needed extra precision.

      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.

      Using local variable for token_cache. · 5ab920d2
      Dmitry Kovalev authored
      The difference with the old code is that originally the whole token_cache
      was initialized with zeros at the beginning of decode_coefs() function.
      Now we set several zero values explicitly with "token_cache[scan[c]] = 0".
