      Limit mv search range for first pass and mbgraph · 35c5d79e
      Yaowu Xu authored
      Both first pass and mbgraph search use block size 16x16 for motion
      estimation. This commit put a limit of motion vector range. The
      effective range allows the entire 16x16 with required subpel
      interpolation input to be completely outside image border, but
      not any further away from image border.

      New mode_info_context storage -- undo revert · ac6093d1
      Scott LaVarnway authored
      mode_info_context was stored as a grid of MODE_INFO structs.
      The grid now constists of pointers to MODE_INFO structs.  The
      MODE_INFO structs are now stored as a stream (decoder only),
      eliminating unnecessary copies and is a little more cache
      friendly.

      For the test clips used, the decoder performance improved
      by ~4.3% (1080p) and ~9.7% (720p).
      
      Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
      and 5.9% (720p).

      Clean ups of the subpel search functions · 71b43b0f
      Deb Mukherjee authored
      Removes some unused code and speed features, and organizes the
      interfaces for fractional mv step functions for use in new speed
      features to come.
      
      In the process a new speed feature - number of iterations per
      step during the subpel search - is exposed.
      
      No change when this parameter is set as the original value of 3.
      
      Results:
      subpel_iters_per_step = 3: baseline
      subpel_iters_per_step = 2: psnr -0.067%, 1% speedup
      subpel_iters_per_step = 1: psnr -0.331%, 3-4% speedup

      Flexible support for various pattern searches · 15b5a6a2
      Deb Mukherjee authored
      Adds a few pattern searches to achieve various tradeoffs
      between motion estimation complexity and performance.
      The search framework is unified across these searches so that a
      common pattern search function is used for all. Besides it will
      be easier to experiment with various patterns or combinations
      thereof at different scales in the future.
      
      The new pattern search is multi-scale and is capable of using
      different patterns at different scales.
      
      The new hex search uses 8 points at the smallest scale
      and 6 points at other scales.
      Two other pattern searches - big-diamond and square are
      also added. Big diamond uses 4 points at the smallest scale and
      8 points in diamond shape at the larger scales.
      Square is very similar conceptually to the default n-step search
      but is somewhat faster since it keeps only one survivor across
      all scales.
      
      Psnr/speed-up results on derf300:
      
      hex: -1.6% psnr%, 6-8% speed-up
      big-diamond: -0.96% psnr, 4-5% speedup
      square: -0.93% psnr, 4-5% speedup

      Make intra prediction pointers RTCD-based. · 8350e7fe
      Ronald S. Bultje authored
      This probably has a mildly negative impact on performance, but will
      (in future commits - or possibly merged with this one) allow SIMD
      implementations of individual intra prediction functions. We may
      perhaps want to consider having separate functions per txfm-size
      also (i.e. 4x4, 8x8, 16x16 and 32x32 intra prediction functions for
      each intra prediction mode), but I haven't played much with that
      yet.

      Change meaning of cpi->sf.first_step and rename. · e606cac0
      Paul Wilkins authored
      Renamed cpi->sf.first_step to cpi->sf.reduce_first_step_size
      and changed its meaning such that it is a delta applied to
      reduce the default first step size (>> x) in the motion search
      rather than an absolute value.
      
      The default first step size is already changed according to the image
      dimensions (smaller for smaller images). cpi->sf.reduce_first_step_size
      now applies a further correction from the default.

      Extend diff MV limit from +/-256 to +/-1024 · 2a5278bd
      Jingning Han authored
      Increase the motion search range by 4x. Change MV_CLASS tree of the
      entropy coding to allow two additional mv classes to cover the
      extended motion vector limit. The codec determines the effective
      motion search range conditioned on the actual frame dimension.
      
      It provides coding gains:
      
      stdhd 0.39%
      yt    0.56%
      hd    0.47%
      
      Major coding performance gains are packed in several sequences with
      intense motion activities, e.g., ped_1080p gains 7% at high bit-rates,
      and on average 3%.
      
      TODO: Need to further tune the rate control and motion search units.

      Use ref_frame_map vice active_ref_idx on the encoder · 800ad0b8
      John Koleszar authored
      This patch makes the encoder's use of ref_frame_map and active_ref_idx
      consistent with the decoder. ref_frame_map[] maps a reference buffer
      index to its actual location in the yv12_fb array, since many
      references may share an underlying buffer. active_ref_idx[] mirrors
      cpi->{lst,gld,alt}_fb_idx, holding the active references in each
      slot.
      
      This also fixes a bug in setup_buffer_inter() where the incorrect
      reference was used to populate the scaling factors.
