      Change scan orders for tx64x64 · c345d4c9
      Debargha Mukherjee authored
      Changes scan orders for 32x64, 64x32 and 64x64 transforms to scan
      the top-left 32x32 coefficients first.

      Generate scan order one frame earlier · fabbd7eb
      Angie Chiang authored
      This should relief the concern of latency incurred by generating
      scan order
      
      The performance on lowres and midres remains neutral

      Revert "Clamp inverse transform coefficients" · 71adf529
      Jingning Han authored
      This reverts commit 79b78b7d.
      
      The transform coefficient range needs some more tuning.
      Before we finalize on that front, directly applying clamping
      would cause multiple unit test failure issues. Hence revert
      this Cl temporarily.

      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.

      cb4x4: Move sub-4X4 TX sizes behind CONFIG_CHROMA_2X2. · fe67ed6a
      Timothy B. Terriberry authored
      cb4x4 itself should not require these sizes.
      
      This simplifies compatibility with other experiments, since we can
      first make them work with cb4x4 (which is now on by default), and
      then worry about chroma_2x2 (which is not) in separate steps.
      
      Encoder and decoder output should remain unchanged.

      Refactor av1_update_neighbors · 0cfaeeaf
      Angie Chiang authored
      Beside above and left positions, additional above-left,
      above-right, and bottom-left positions are added as
      neighbor candidates.
      
      In av1_update_neighbors, two available positions will be picked as
      context neighbors.
      
      The picking priority is
      above -> left -> above-left -> above->right -> bottom->left
