      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.

      Support affine/homography models for global motion · b0f6bd44
      Debargha Mukherjee authored
      With this patch affine or homography models can be enabled
      by simply changing the value of the GLOBAL_TRANS_TYPES
      macro in common/mv.h to 4 and 5 respectively. Currently
      it is left at supporting only rotzoom. There is a small
      gain with enabling affine.
      Also refactors costing to change based on the model type.
