      Change scaling of rectangular fwd transforms · f0aa420c
      Debargha Mukherjee authored
      Modifies the C fwd txfms to have correct scaling. Rectangular
      transforms now are always implemented in a way that the samller
      side is transformed first.
      The SSE2 tests are temporarily disabled until the SSSE2 code
      is modified to be consistent with the C code.
      Also includes a fdct32 fix.
      borgtest results show a slight improvement.

      Disable filtering for Cb and Cr components · 818e42a7
      Debargha Mukherjee authored
      The parameters are optimized only on Y, so disable chrominance
      filtering for now. Later we can extend the syntax to have
      separate parameters for the chrominance, or optimize the
      parameters jointly over luminance and chrominance components.
      lowres: -0.676% (from -0.759%) becomes a little worse
      midres: -1.837% (from -1.520%) substantial improvement
      hdres: pending

      1. The ethread test can only be ran when both the encoder and decoder are
      available. This is also true for ext_tile test.
      2. Modify the ethread speed test range to speed 0 to 3 for AV1.

      Not to call reset_use_upsampled_references() while encoding key frames · fe1e58ec
      Yunqing Wang authored
      A crash was reported while encoding >1080p file using best mode.
      (aom issue 107 and issue 108). The cause was that the speed features
      were initialized using good mode in AV1. The patch(commit f330ca)
      disabled the upsampled reference usage only for good mode, but not for
      best mode. So, for 1st key frame, the encoder incorrectly called
      reset_use_upsampled_references() that caused the segfault.
      The patch(commit e4e93b) disabled the upsampled reference usage for all
      encoding modes and resolved the issue. This patch fixed issue 108 and
      further made sure the upsampled references would be used correctly.

      Remove saturate_int16 from fdct_round_shift · 48c06da2
      Angie Chiang authored
      1) Not every transform's internal signal is designed to fit in 16 bits.
      2) If overflow happens in this function, it indicates that we need to
      adjust the txfm's scaling. We shouldn't mute the overflow signal.
      3) Saturation might be handy when all of our transform design are stable,
      but I don't think we are at the stable point yet.
      4) This will fix C/Trans16x16DCT.AccuracyCheck/1 failure in highbd mode.
