      obj_int_extract for Visual Studio · 128d2c23
      Johann authored
      Enable extraction of assembly offsets from compiled examples in MSVS.
      This will allow us to remove some stub functions from x86 assembly since
      we will be able to reliably determine structure offsets at compile time.
      
      see ARM code for examples:
      vp8/encoder/arm/armv5te/
      vpx_scale/arm/neon/

      Added missing format specifier in print statement · 6daacdb7
      Adrian Grange authored
      Printout of firstpass stats for frame had one fewer
      format specifiers than arguments.

      Removed firstpass motion map · ed40ff9e
      Adrian Grange authored
      The firstpass motion map consists of an 8-bit flag for
      each MB indicating how strongly the firstpass code
      believes it should be filtered during the second pass
      ARNR filtering.
      
      For long or large format material the motion map can
      become extremely large and hamper the operation of
      the encoding process.
      
      This change removes the motion map altogether, leaving
      the second pass to rely on the magnitude of the motion
      compensated error to determine the filter weight to
      use for the MB during ARNR filtering.
      
      Tests on the derf set indicate that the effect of this
      change is neutral, with some small wins and losses. The
      motion map has therefore been removed based on
      a cost/benefit evaluation.

      Fix incorrect macroblock counts in twopass rate control · f3e9e2a0
      James Berry authored
      The previous calculation of macroblock count (w*h)/256
      is not correct when the width/height are not multiples of
      16. Use the precalculated macroblock count from
      cpi->common instead. This manifested itself as a divide
      by zero when the number of pixels was less than 256.
      num_mbs updated in estimate_max_q, estimate_q,
       estimate_kf_group_q, and estimate_cq

      Fix format-string warning · fe9a604b
      Ralph Giles authored
      Cast size_t to (unsigned long) and print it with the %lu format
      string, which is more portable than C99's explict %zu for size_t.
      
      This truncates on Windows x64 but otherwise works on 32 and 64 bit
      platforms. In practice the stats file is unlikely to be so large.

      Improved key frame detection. · bc9c30a0
      Paul Wilkins authored
      In some cases where clips have been encoded with
      borders (eg. some wide-screen content where there is a
      border top and bottom and slide shows containing portrait
      format photographs (border left and right)) key frames were
      not being correctly detected.
      
      The new code looks to measure cases where a portion of
      the image can be coded equally easily using intra or inter
      modes and where the resulting error score is also very low.
      These "neutral" areas are then discounted in the key frame
      detection code.

      Improved KF insertion after fades to still. · 9fc8cb39
      Paul Wilkins authored
      This code extends what was previously done for GFs, to pick
      cases where insertion of a key frame after a fade (or other
      transition or complex motion)  followed by a still section, will
      be beneficial and will reduce the number of forced key frames.
