      Clamp inverse transform coefficients · 79b78b7d
      Sebastien Alaiwan authored
      When --enable-coefficient-range-checking isn't specificed, clamp the
      coefficient at each stage.
      
      This doesn't change the decoder behaviour for existing AV1 streams.
      However, some AV1 bitstreams that would have been rejected by the
      decoder as illegal (range check failure) are now legal bitstreams.
      
      There is no impact on video quality.

      Resolve compiler warning when highbd is off · 105eecf4
      Jingning Han authored
      The highbd_clip_pixel_add() function is generalized to be used in
      the regular 8 bit path. Move its defintions outside the highbd
      experimental flag.
      
      This resolves the comiler warning in unit tests when high bit-depth
      is turned off.

      Drop support for CONFIG_EMULATE_HARDWARE · c6a48a25
      Sebastien Alaiwan authored
      This experiment complexifies DSP function dispatch, without bringing
      any real value (it's non-normative arbitrary behaviour).
      Moreover, it only has an effect on obsolete transforms, the new ones
      don't implement this mechanism.

      Move range checks into WRAPLOW · aa909836

      Provides more comprehensive coverage for --enable-coefficient-checking.
      The intent is to make the --enable-coefficient-checking option
      consistent with the VP9 spec.

      Factor inverse transform functions into vpx_dsp · e8b133c7
      Jingning Han authored
      This commit moves the module inverse transform functions from vp9
      to vpx_dsp folder. The hybrid transform wrapper functions stay in
      the vp9 folder, since it involves codec-specific data structures.

      Code refactor on InterpKernel · 7186a2dd
      Zoe Liu authored
      It in essence refactors the code for both the interpolation
      filtering and the convolution. This change includes the moving
      of all the files as well as the changing of the code from vp9_
      prefix to vpx_ prefix accordingly, for underneath architectures:
      (1) x86;
      (2) arm/neon; and
      (3) mips/msa.
      The work on mips/drsp2 will be done in a separate change list.

      Separate the common coefficient constant into vpx_dsp/txfm_common.h.
      Move the SSE2 macro definitions to vpx_dsp/x86/txfm_common_sse2.h.

      Refactored idct routines and headers · 3a8c43a4
      Peter de Rivaz authored
      This change is made in preparation for a
      subsequent patch which adds acceleration
      for the highbitdepth transform functions.
      
      The highbitdepth transform functions attempt
      to use 16/32bit sse instructions where possible,
      but fallback to using the C implementations if
      potential overflow is detected.  For this reason
      the dct routines are made global so they can be
      called from the acceleration functions in the
      subsequent patch.

      James Zern authored
      This reverts commit eafc8c9c.
      
      tran_low_t/tran_high_t don't belong in a public header, they're private.
      Similarly the public headers shouldn't rely on config defines,
      vpx_config.h isn't installed.

      This commit fixes a compiling error in vp9_idct.h, where the codec
      checks that the intermediate steps of transformation fit within
      16-bit length. The issue was due to broken file dependency.

      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.

      configure: add --enable-coefficient-range-checking · 0a2b25dc
      Yaowu Xu authored
      This commit adds a configure time option used to enable strict error
      checking in decoder to make sure intermediate stage cofficients of
      inverse transforms are within valid range of signed 16 bit integer.
      
      For valid VP9 input streams, intermediate stage coefficients should
      always stay within the range of a signed 16 bit integer. Coefficients
      can go out of this range for invalid/corrupt VP9 streams. However,
      strictly checking this range for every intermediate coefficient can
      be a burden for decoder, therefore such validation is only enabled
      with configure option --enable-coefficient-range-checking.
