      Scott LaVarnway authored
      This patch eliminates the intermediate diff buffer usage by
      combining the short idct and the add residual into one function.
      The encoder can use the same code as well.

      to set the threshold for this correctly at the moment.

      convolve: support larger blocks, fix asm saturation bug · a9ebbcc3
      John Koleszar authored
      Updates the common convoloution code to support blocks larger than
      16x16, and rectangular blocks. This uncovered a bug in the SSSE3
      filtering routines due to the order of application of saturation.
      This commit fixes that bug, adjusts the unit test to bias its
      random values towards the extremes, and adds a test to ensure that
      all filters conform to the expected pairwise addition structure.

      fix superframe index marker masks · bd9cd9a1
      John Koleszar authored
      The superframe index marker byte carries data in the lower 5 bits. Only the
      upper 3 should be used as part of the mask to detect it. By masking with
      0xf0, the previous code was incorrect for frames over 65k bytes.

      Add 'superframe' index · 522d4bf8
      John Koleszar authored
      A 'superframe' is a group of frames that share the same PTS, but have a
      defined decoding order. This commit adds the ability to append an index
      to such a group of frames, allowing for random access to the constituent
      frames. This could be useful for frame-level parallelism or partial
      decoding in a multilayer scenario.
      Decoding the stream serially without such an index should work as a
      fallback, and VP9/TestSuperframeIndexIsOptional verifies that.

      convolve test: validate 1D filters are 1D · 04c24078
      John Koleszar authored
      Since the 8-tap lowpass filter is non-interpolating, the results are
      different between applying it at whole-pel values and not. This
      means that 1D-only versions are requried to be implemented, as
      opposed to being an optimization of the 2D case. Calling the 2D
      filter instead of the horizontal-only filter is not equivalent
      in this case. Update the test to pass invalid filters to the
      unused stage of the 1D-only calls, to verify they're unused.

      Spatial resamping of ZEROMV predictors · eb939f45
      John Koleszar authored
      This patch allows coding frames using references of different
      resolution, in ZEROMV mode. For compound prediction, either
      reference may be scaled.
      To test, I use the resize_test and enable WRITE_RECON_BUFFER
      in vp9_onyxd_if.c. It's also useful to apply this patch to

      Ensure that all inter prediction goes through a common code path
