      Don't calculate chroma data in monochrome mode · af8e2648
      Imdad Sardharwalla authored
      Encoder: Prior to this patch, some chroma data was calculated and
      later discarded when in monochrome mode. This patch ensures that
      the chroma planes are left uninitialised and that chroma
      calculations are not performed.
      Decoder: Prior to this patch, some chroma calculations were still
      being performed in monochrome mode (e.g. loop filtering). This
      patch ensures that calculations are only performed on the y
      plane, with the chroma planes being set to a constant.

      Fix Valgrind warning in av1_pick_filter_restoration · b08544de
      Imdad Sardharwalla authored
      Some array elements were defined and left uninitialised. This wasn't causing a
      problem, as the elements were later ignored, but it did cause Valgrind to
      produce warnings.
      The function now initialises the full array immediately after its definition in
      order to quiet these warnings.

      Optimise self-guided restoration SIMD functions · f32dabd2
      Imdad Sardharwalla authored
      Improvements have been made to calc_ab for both the
      SSE4.1 and AVX2 versions of the self-guided filter.
      These result in an increase in the speed of between
      3% and 5% depending on the bit depth.

      SIMD implementation of horz superres · 454697ca
      Imdad Sardharwalla authored
      SSE4.1 implementations of av1_convolve_horiz_rs and
      av1_highbd_convolve_horiz_rs have been added, along
      with the corresponding speed and correctness tests.
      The interp_taps argument was defunct and has now been
      removed and replaced with the UPSCALE_NORMATIVE_TAPS
      Code associated with values of UPSCALE_NORMATIVE_TAPS
      that are no longer used has been removed.

      Rework fast tx type search speed feature for intra frame · 00121edb
      Hui Su authored
      Fix tx type as the default type and search for the best prediction mode;
      then do a final search for the best tx type.
      When it's enabled at speed 0, encoding speed increases to 3x with 2%
      compression loss on keyframes. It's currently turned on for speed
      2 and above.
