      Reduce partial frame copy in encoder's pick_filter_level_fast · de828094
      Attila Nagy authored
      The partial frame copy function used to copy an extra 8 lines above
      and  below. The partial frame filtering can only modify 3 pixel rows
      above the partial frame. Reduce copy to bare minimum needed, which is
      4 lines, so that partial filtering on copied frame is possible.
      
      Define the "magic" fraction number for partial filtering in
      loopfilter.h .

      fix sharpness bug and clean up · a04ed0e8
      Johann authored
      sharpness was not recalculated in vp8cx_pick_filter_level_fast
      
      remove last_filter_type. all values are calculated, don't need to update
      the lfi data when it changes.
      
      always use cm->sharpness_level. the extra indirection was annoying.
      
      don't track last frame_type or sharpness_level manually. frame type
      only matters for motion search and sharpness_level is taken care of in
      frame_init
      
      move function declarations to their proper header

      New loop filter interface · 62295844
      Attila Nagy authored
      Separate simple filter with reduced no. of parameters.
      MB filter level picking based on precalculated table. Level table updated for
      each frame. Inside and edge limits precalculated and updated just when
      sharpness changes. HEV threshhold is constant.
      ARM targets use scalars and others vectors.
      
      Change works only with --target=generic-gnu
      All other targets have to be updated!

      remove simpler_lpf · 01527e74
      Johann authored
      the decision to run the regular or simple loopfilter is made outside the
      function and managed with pointers
      
      stop tracking the option in two places. use filter_type exclusively

      Eliminate more warnings. · 97b766a4
      Timothy B. Terriberry authored
      This eliminates a large set of warnings exposed by the Mozilla build
       system (Use of C++ comments in ISO C90 source, commas at the end of
       enum lists, a couple incomplete initializers, and signed/unsigned
       comparisons).
      It also eliminates many (but not all) of the warnings expose by newer
       GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
       without checking the return values).
      There are a few spurious warnings left on my system:
      
      ../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
       uninitialized in this function
      gcc seems to be unable to figure out that the value shortcut doesn't
       change between the two if blocks that test it here.
      
      ../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
       expression >= 0 is always true
      ../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
       expression >= 0 is always true
      This is true, so far as it goes, but it's comparing against an enum,
       and the C standard does not mandate that enums be unsigned, so the
       checks can't be removed.

      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.

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
