      Improve SSE2 loopfilter functions · bead039d
      Yunqing Wang authored
      Restructured and rewrote SSE2 loopfilter functions. Combined u and
      v into one function to take advantage of SSE2 128-bit registers.
      Tests on test clips showed a 4% decoder performance improvement on
      Linux desktop.

      The generated project is vpx.vcproj, change vpx_decoder references to
      match. Remove .rules file dependency as it will be pulled from the
      source tree.

      Fixed buffer selection for UV in AltRef filtering · aa8fe0d2
      Adrian Grange authored
      Corrected setting of "which_buffer" for U & V cases to match that
      used for Y, i.e. to refer to the temporally most recent frame of
      those to be filtered.

      Redo the forward 4x4 dct · d0dd01b8
      Yaowu Xu authored
      The new fdct lowers the round trip sum squared error for a
      4x4 block ~0.12. or ~0.008/pixel. For reference, the old
      matrix multiply version has average round trip error 1.46
      for a 4x4 block.
      
      Thanks to "derf" for his suggestions and references.

      vp8cx : bestsad declared and initialized incorrectly. · a5906668
      Fritz Koenig authored
      bestsad needs to be a int and set to INT_MAX because at the end
      of the function it is compared to INT_MAX to determine if there
      was a match in the function.

      vp8cx : bestsad declared and initialized incorrectly. · cecdd73d
      Fritz Koenig authored
      bestsad should be an int initialized to INT_MAX.  The optimized
      SAD function expects a signed value for bestsad to use for comparison
      and early loop termination.  When no match is made, which is
      determined by a comparison of bestsad to INT_MAX, INT_MAX is returned.

      Remove INLINE/FORCEINLINE · 5e344614

      These are mostly vestigial, it's up to the compiler to decide what
      should be inlined, and this collided with certain Windows platform SDKs.

      This information is in git, so it's better to use that as a source than
      updating this file manually. This script can be run manually at release
      time for now, or we can set up a cron job sometime in the future.

      Avoid encoding garbage when ivfenc encounters an unsupported Y4M file. · e703af97
      Tom Finegan authored
      This change stops ivfenc from treating unsupported Y4M files as raw
      input.
      
      For example, if given an interlaced Y4M file, ivfenc treated the input
      as if it were raw data because the unsupported Y4M file case previously
      fell through without being handled.

      gen_scalers: fix 64-bit integer promotion bug · bbfeefc7
      John Koleszar authored
      i needs to be treated as signed to get the proper indexing on 64-bit
      platforms. This behavior was accidentally reverted when fixing an
      unsigned/signed comparison warning.

      Change bitreader to use a larger window. · c17b62e1
      Timothy B. Terriberry authored
      Change bitreading functions to use a larger window which is refilled less
       often.
      
      This makes it cheap enough to do bounds checking each time the window is
       refilled, which avoids the need to copy the input into a large circular
       buffer.
      This uses less memory and speeds up the total decode time by 1.6% on an ARM11,
       2.8% on a Cortex A8, and 2.2% on x86-32, but less than 1% on x86-64.
      
      Inlining vp8dx_bool_decoder_fill() has a big penalty on x86-32, as does moving
       the refill loop to the front of vp8dx_decode_bool().
      However, having the refill loop between computation of the split values and
       the branch in vp8_decode_mb_tokens() is a big win on ARM (presumably due to
       memory latency and code size: refilling after normalization duplicates the
       code in the DECODE_AND_BRANCH_IF_ZERO and DECODE_AND_LOOP_IF_ZERO cases.
      Unfortunately, refilling at the end of vp8dx_bool_decoder_fill() and at the
       beginning of each decode step in vp8_decode_mb_tokens() means the latter
       requires an extra refill at the end.
      Platform-specific versions could avoid the problem, but would require most of
       detokenize.c to be duplicated.
