      [spatial svc]Implement alt reference frames · e899859c
      Minghai Shang authored
      All changes are for spatial svc only.
      1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
      2. Use golden reference idx for spatial reference
      3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
      4. Add "auto-alt-refs" in svc options

      Dual ARF changes: Buffer index selection. · 60244ec1
      Paul Wilkins authored
      Add indirection to the section of buffer indices.
      This is to help simplify things in the future if we
      have other codec features that switch indices.
      Limit the max GF interval for static sections to fit
      the gf_group structures.

      Experiment for mid group second arf. · 2e430cba
      Paul Wilkins authored
      This patch implements a mechanism for inserting a second
      arf at the mid position of arf groups.
      It is currently disabled by default using the flag multi_arf_enabled.
      Results are currently down somewhat in initial testing if
      multi-arf is enabled. Most of the loss is attributable to the
      fact that code to preserve the previous golden frame
      (in the arf buffer) in cases where we are coding an overlay
      frame, is currently disabled in the multi-arf case.

      These tables were almost the same and for
      VBR the arf table was not used at all.

      Rate control adjustment. · 38ff3e32
      Paul Wilkins authored
      Small adjustment to the active Q range calculations.
      These changes should slightly extend the available Q range
      for KF/GF/ARF and narrow it for other frames.
      The results for this change in isolation are broadly positive
      for SSIM and average PSNR and slightly up but mixed for opsnr.

      The end_useage parameter  is confusingly named since it
      now actually defines the rate control method used.

      Add experimental VBR adaptation method. · 085f76e5
      Paul Wilkins authored
      Add code to monitor over and under spend and
      apply limited correction to the data rate of subsequent
      frames. To prevent the problem of starvation or overspend
      on individual frames (especially near the end of a clip) the
      maximum adjustment on a single frame is limited to a %
      of its un-modified allocation.

      Fix rate control bug. · 658daf36
      Paul Wilkins authored
      Fix rate control bug whereby the rate factor heuristics
      were being updated on arf overlays causing a rate surge
      for a few frames followed by a corrective drop.
      This fix eliminates many of the overshoot problems that
      we were seeing on hard clips (even without applying
      stricter vbr rate control) and also helps quality on
      almost all clips with some hard clips improving by >5%.
      Overall quality results measured at speed 2.
      Derf  +1.78% opsnr , +2.44% SSIM
      Stdhd +2.41% opsnr, +2.85% SSIM

      Change Qlimit for arf kf. · d83f6f06
      Paul Wilkins authored
      The limits applied under the flag
      behaved in an undesirable way if the gap between
      active_worst_quality and active_best_quality was
      In this patch, the adjustment is made using the
      vp9_compute_qdelta_by_rate() function and fixed
      rate multiplier values. Hence it is not impacted by
      the relative value of active_best_quality.
