      Remove experimental flag of EXT_TX · 3bac9928
      Sebastien Alaiwan authored
      This experiment has been adopted, we can simplify the code
      by dropping the associated preprocessor conditionals.

      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.

      Add configurations for hbd identity transform · 3eed4175
      Sarah Parker authored
      This adds the proper cfgs to av1_{inv/fwd}_txfm1d_cfg for
      the identity transform so all hbd transforms can use
      the same codepath. This has no impact on performance
      since the new identity transforms that correspond with
      the cfgs are not yet being called. Once this is checked in,
      we should be able to delete all deprecated transform functions
      and have a single code flow for all hbd transforms.

      Huge speedup for range checking. · 1a02439f
      Sebastien Alaiwan authored
      De-duplicate implementations of 'range_check', and use precomputed pixel value
      boundaries instead of computing the log2 of each pixel value.
      Overall speedup: encoding with enabled-range checks goes 3.3 times
      faster.
