      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.

      ARM WinCE VS8 build update · a23ec527
      James Zern authored
      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.

      Further adjustment of RD behaviour with Q and Zbin. · 1ca39bf2
      Paul Wilkins authored
      Following conversations with Tim T (Derf) I ran a large number of
      tests comparing the existing polynomial expression with a simpler
      ^2 variant. Though the polynomial was sometimes a little better at
      the extremes of Q it was possible to get close for most clips and
      even a little better on some.
      
      This code also changes the way the RD multiplier is calculated
      when the ZBIN is extended to use a variant of the same ^2
      expression.
      
      I hope that this simpler expression will be easier to tune further
      as we expand our test set and consider adjustments based on content.

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

      ivfenc: correct fixed kf interval, --disable-kf · b1e36f28
      John Koleszar authored
      ivfenc was setting the VPX_KF_FIXED mode when the kf_min_dist and
      kf_max_dist parameters were set to each other. This flag actually means
      that keyframes are disabled, and that name was deprecated to avoid
      confusion such as this. Instead, a new option is exposed for setting the
      VPX_KF_DISABLED mode, and the intervals are passed through to the codec,
      which will do automatic placement at a fixed interval as expected.
