      Ban op->idc that may drop all layer-specific OBUs · 50e876c6
      Wan-Teh Chang authored
      If c->operating_point_idc is nonzero and either bits 0-7 or bits 8-11 in
      it are all 0s, it will cause dav1d_parse_obus() to drop all
      layer-specific OBUs. Prohibit any op->idc with such properties because
      it could be selected as c->operating_point_idc.

      arm64: mc: Apply tuning from w4/w8 case to w2 case in 16 bpc 8tap_hv · 4ae3f5f7
      Martin Storsjö authored
      Narrowing the intermediates from the horizontal pass is beneficial
      (on most cores, but a small slowdown on A53) here as well. This
      increases consistency in the code between the cases.
      
      (The corresponding change in the upcoming arm32 version is beneficial
      on all tested cores except for on A53 - it helps, on some cores a lot,
      on A7, A8, A9, A72, A73 and only makes it marginally slower on A53.)

      cli: Use proper integer math in Y4M PAR calculations · 3bfe8c7c
      Henrik Gramner authored
      The previous floating-point implementation produced results that were
      sometimes slightly off due to rounding errors.
      
      For example, a frame size of 432x240 with a render size of 176x240
      previously resulted in a PAR of 98:240 instead of the correct 11:27.
      
      Also reduce fractions to produce more readable numbers.

      checkasm: Add ifdefs around the readtime check · 5bbd9632
      Martin Storsjö authored
      This fixes building in configurations where no readtime implementation
      is available at all, such as MSVC targeting 32 bit ARM.
      
      This was missed when the check was added in
      95a19254.

      checkasm: Enforce declare_func to be outside of check_func · 0b824944
      Martin Storsjö authored
      Move the declaration of func_ref/func_new into declare_func. This
      enforces that declare_func is a scope outside of/before check_func.
      
      This ensures that if the signal handler is triggered, we rewind
      to a scope outside of check_func, where check_func makes sure we
      don't rerun the test that just triggered the signal handler.
