      Propagate macroblock MV to subblocks for error concealment · 91206793
      John Koleszar authored
      EC expects the subblock MVs to be populated, but
      f1d6cc79 removed this code. This
      commit restores it, protected by CONFIG_ERROR_CONCEALMENT. May move this
      to the EC code more directly in the future.

      Disable error concealment until first key frame is decoded · 3e10be93
      Stefan Holmer authored
      When error concealment is enabled the first key frame must
      be successfully received before error concealment is activated.
      Error concealment will be activated when the delta following
      delta frame is received.
      
      Also fixed a couple of bugs related to error tracking in
      multi-threading. And avoiding decoding corrupt residual
      when we have multiple non-resilient partitions.

      Fix potential OOB read with Error Concealment · 810a06b1
      John Koleszar authored
      This patch fixes an OOB read when error concealment is enabled and the
      partition sizes are corrupt. The partition size read from the bitstream
      was not being validated in EC mode.

      Fix source buffer selection · 238dae86
      John Koleszar authored
      This patch fixes a bug in the interaction between the recode loop and
      spatial resampling. If the codec was in a spatial resampling state,
      and a subsequent iteration of the recode loop disables resampling,
      then the source buffer must be reset to the unscaled source.

      Adjust half-pixel only search · b9f19f89
      Yunqing Wang authored
      Changed motion search in vp8_find_best_half_pixel_step() to be the
      same as in vp8_find_best_sub_pixel_step(), which checks 5 points
      instead of 8 points. This only affects real-time mode with
      cpu-used >=9. Tests showed it gives 2% encoding speedup with
      a quality loss(psnr) of up to 0.5%.

      Convert rc_max_intra_bitrate_pct to control · 1654ae9a
      John Koleszar authored
      Since this is the only ABI incompatible change since the last release,
      convert it to use the control interface instead. The member of the
      configuration struct is replaced with the VP8E_SET_MAX_INTRA_BITRATE_PCT
      control.
      
      More significant API changes were expected to be forthcoming when this
      control was first introduced, and while they continue to be expected,
      it's not worth breaking compatibility for only this change.

      Preload reference area in sub-pixel motion search (real-time mode) · 2f2302f8
      Yunqing Wang authored
      This change implemented same idea in change "Preload reference area
      to an intermediate buffer in sub-pixel motion search." The changes
      were made to vp8_find_best_sub_pixel_step() and vp8_find_best_half
      _pixel_step() functions which are called when speed >= 5. Test
      result (using tulip clip):
      
      1. On Core2 Quad machine(Linux)
      rt mode, speed (-5 ~ -8), encoding speed gain: 2% ~ 3%
      rt mode, speed (-9 ~ -11), encoding speed gain: 1% ~ 2%
      rt mode, speed (-12 ~ -14), no noticeable encoding speed gain
      
      2. On Xeon machine(Linux)
      Test on speed (-5 ~ -14) didn't show noticeable speed change.

      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

      Preload reference area to an intermediate buffer in sub-pixel motion search · 20bd1446
      Yunqing Wang authored
      In sub-pixel motion search, the search range is small(+/- 3 pixels).
      Preload whole search area from reference buffer into a 32-byte
      aligned buffer. Then in search, load reference data from this buffer
      instead. This keeps data in cache, and reduces the crossing cache-
      line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux)
      showed encoder speed improvement:
        3.4%   at --rt --cpu-used =-4
        2.8%   at --rt --cpu-used =-3
        2.3%   at --rt --cpu-used =-2
        2.2%   at --rt --cpu-used =-1
      
      Test on Atom notebook showed only 1.1% speed improvement(speed=-4).
      Test on Xeon machine also showed less improvement, since unaligned
      data access latency is greatly reduced in newer cores.
      
      Next, I will apply similar idea to other 2 sub-pixel search functions
      for encoding speed > 4.
      
      Make this change exclusively for x86 platforms.

      Increase chrow row alignment to 16 bytes. · 7d1b37cd
      Timothy B. Terriberry authored
      This is done by expanding luma row to 32-byte alignment, since
       there is currently a bunch of code that assumes that
       uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c,
       common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm,
       encoder/temporal_filter.c, and possibly others; I haven't done a
       full audit).
      It also uses replaces the hardcoded border of 16 in a number of
       encoder buffers with VP8BORDERINPIXELS (currently 32), as the
       chroma rows start at an offset of border/2.
      Together, these two changes have the nice advantage that simply
       dumping the frame memory as a contiguous blob produces a valid,
       if padded, image.

      Improved 1-pass CBR rate control · b5ea2fbc
      John Koleszar authored
      This patch attempts to improve the handling of CBR streams with
      respect to the short term buffering requirements. The "buffer level"
      is changed to be an average over the rc buffer, rather than a long
      running average. Overshoot is also tracked over the same interval
      and the golden frame targets suppressed accordingly to correct for
      overly aggressive boosting.
      
      Testing shows that this is fairly consistently positive in one
      metric or another -- some clips that show significant decreases
      in quality have better buffering characteristics, others show
      improvenents in both.
