      Relocate memory operations for common code · 1d7ccd53
      Johann authored
      With the sad functions, and hopefully the variance functions soon,
      moving to the vpx_dsp location, place the defines used in the
      reference C code in a common location.

      Correct the miscalculation in uv dimensions · 4bca73b6
      Yaowu Xu authored
      The calculation of required extension used in HBD case was wrong due
      to rounding for UV when y dimension is odd. This commit replace the
      computation with correct version.
      
      This fixes a crash caused by writting beyond buffer boundary.

      Enable decoder to pass through color space info · 6b223fcb
      Yaowu Xu authored
      This commit added a field to vpx_image_t for indicating color space,
      the field is also added to YUV_BUFFER_CONFIG. This allows the color
      space information pass through the decoder from input stream to the
      output buffer.
      
      The commit also updated compare_img() function with added verification
      of matching color space to ensure the color space information to be
      correctly passed from encode to decoder in compressed vp9 streams.

      Add support for setting byte alignment on the Y, U, and V plane of the
      reference buffers. The byte alignment must be a power of 2, from 32 to
      1024. A value of 0 sets legacy alignment.

      Remove asm offset dependencies · 6eec73a7
      Johann authored
      The obj_int_extract code is no longer worth maintaining. It creates
      significant issues when adapting for different build systems and no
      longer offers as significant of a performance benefit due to
      improvements in intrinsics.
      
      Source files will remain until the various third-party builds are updated.
      
      The neon fast quantizer has been moved to intrinsics. The armv6 version
      has been removed because so few remaining targets require it.
      
      Compilers and processors have improved significantly since the
      pack_tokens code was written. The assembly is no longer faster than the
      C code.
      
      pack_tokens were the only optimizations for the armv5te targets so the targets
      will be removed after the test infrastructure has been updated.

      Remove memset of every external frame buffer. · 175d9dfe
      Frank Galligan authored
      Libvpx was memseting every external frame buffer before decode. This
      was to work around a valgrind issue in our C loop filter. Most of
      the time this was not needed and we have noticed some significant
      performance loss on some platforms. Now we require the application to
      zero out the buffers if it is using external frame buffers.

      Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
      Also includes most vpx level high bit-depth functions. However
      encode/decode in the highbitdepth profiles will not work until
      the rest of the code is in place.

      Set and use uv_crop_[width|height] · e956c007
      Johann authored
      Ensure consistent border extension by rounding uv_crop_* at image
      creation time. Where it was rounded problems could arise with the right
      and bottom extensions.
      When padding = 32, y_width = 64, and y_crop_width = 63:
       (padding + width - crop_width + 1) / 2
       32 + 64 - 63 + 1 should equal 32 *but*
       32 + 1 + 1 equals 34 giving a right buffer of 17 instead of 16.
      By calculating uv_crop_* earlier we round up at the appropriate time and
      for the same values:
       (y_crop_width + 1) / 2
       63 + 1 / 2
       64
       (padding / 2) + uv_width - uv_crop_width
       16 + 16 - 16
       16

      significantly speeds up file generation.
      
      the goal of this change is to convert rtcd.sh to perl as directly as
      possible to allow for simple comparison. future changes can make it more
      perl-like.

      Add get release decoder frame buffer functions. · e8e15279
      Frank Galligan authored
      This CL changes libvpx to call a function when a frame buffer
      is needed for decode. Libvpx will call a release callback when
      no other frames reference the frame buffer. This CL adds a
      default implementation of the frame buffer callbacks. Currently
      only VP9 is supported. A future CL will add support for
      applications to supply their own frame buffer callbacks.
