      Fix a bug in jnt_comp · 5b5f3d50
      Cheng Chen authored
      (1). index may go out side of range
      (2). when d0 <= d1, comparison is invalid.
      Performance impact on Google lowres testset:
      Turn on jnt_comp vs baseline,
      Without fix: -0.211% gain
      With fix: -0.357% gain

      Added a test for monochrome encoding. · 26ac0478
      Imdad Sardharwalla authored
      The test encodes 5 frames of a video using the --monochrome flag and
      verifies that the decoded frames satisfy:
      - each frame's monochrome flag is set to 1
      - each frame's U and V planes are set to a constant, and this constant
        is the same for all decoded frames
      - the initial frame's Y PSNR value is 'high enough'
      - the Y PSNR values remain fairly constant across all of the frames

      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.

      By avoiding break CPU's pipeline,
      this patch achieves a small encoder
      speedup at the range of 0.2%~0.71%.

      Reorder operation to avoid UBsan warning · 6394f0fd
      Yaowu Xu authored
      The original order of operations lead to all variables upgraded to
      unsigned int during computation, and enc->cnt being negative then
      would cause UBsan warning.
