      abstract apply_temporal_filter · 092b5bef
      Johann authored
      allow for optimized versions of apply_temporal_filter
      (now vp8_apply_temporal_filter_c)
      
      the function was previously declared as static and appears to have been
      inlined. with this change, that's no longer possible. performance takes
      a small hit.
      
      the declaration for vp8_cx_temp_filter_c was moved to onyx_if.c because
      of a circular dependency. for rtcd, temporal_filter.h holds the
      definition for the rtcd table, so it needs to be included by onyx_int.h.
      however, onyx_int.h holds the definition for VP8_COMP which is needed
      for the function prototype. blah.

      propagate user private data on decode · c49f49b1
      John Koleszar authored
      The pointer passed in the user_priv argument to vpx_codec_decode()
      should be propagated through to the corresponding output frame and
      made available in the image's user_priv member. Fixes issue #252

      Add psnr/ssim tuning option · b0da9b39
      John Koleszar authored
      Add a new encoder control, VP8E_SET_TUNING, to allow the application
      to inform the encoder that the material will benefit from certain
      tuning. Expose this control as the --tune option to vpxenc. The args
      helper is expanded to support enumerated arguments by name or value.
      
      Two tunings are provided by this patch, PSNR (default) and SSIM.
      Activity masking is made dependent on setting --tune=ssim, as the
      current implementation hurts speed (10%) and PSNR (2.7% avg,
      10% peak) too much for it to be a default yet.

      Inform caller of decoder about updated references · 2a87491f
      Henrik Lundin authored
      Inform the caller of the decoder if a decoded frame updated last,
      golden, or altref frames, required for realtime communication
      proposed in document VP8 RTP payload format.
      
      Added a new vpx_codec_control called VP8D_GET_LAST_REF_UPDATES, to be
      called after vpx_codec_decode. The control will indicate which of the
      reference frames that were updated by setting the 3 LSBs in the input
      int (pointer).

      Changed segmentation check order · 64baa8df
      Scott LaVarnway authored
      In SPLITMV, the 8x8 segment will be checked first.  If the 8x8 rd
      is better than the best, we check the other segments.  Otherwise
      bail.  Adjustments to the thresh_mult were necessary to make
      up for the initial quality loss.
      The performance improved by 20% (average) for good quality,
      speed 0 and speed 1, while the overall quality remained the same.

      Adjusted breakout RD for SPLITMV · 81cdeb71
      Scott LaVarnway authored
      vp8_rd_pick_best_mbsegmentation looks at y only.  The new
      breakout does not include the frame cost, the prob_skip_false
      cost, or the uv rate.  Performance improved by a few percent
      and the quality remained the same.

      Correct q_low and q_high limits for the recode loop · c63fc881
      Paul Wilkins authored
      Corrected the initial Q range limits for the recode loop
      to reflect the current allowed range for the frame.
      
      In experimental work on constrained quality this bug was
      causing unnecessary recodes.

      Change to inter_minq table. · cec6a596
      Paul Wilkins authored
      The inter_minq table controls the range of quantizers available
      for a particular frame in two pass relative to a max Q value.
      
      The changes reduces the range somewhat. The effect of this
      was a small increase (0.3% average) in psnr for the test set
      but it should also help encode speed somewhat for higher
      quality modes as it will reduce the number of iterations in the
      recode loop.
      
      The change damps the range of quantizers available locally
      within a section of a clip and should therefore help keep quality
      more uniform. If there is systematic overshoot or undershoot the
      range can shift gradually to accommodate. However, there is
      some increased risk of overshoot or undershoot against the target
      bit rate in VBR mode and this risk will be more pronounced for short
      clips.

      Improve MV prediction accuracy to achieve performance gain · c3bbb291
      Yunqing Wang authored
      Add vp8_mv_pred() to better predict starting MV for NEWMV
      mode in vp8_rd_pick_inter_mode(). Set different search
      ranges according to MV prediction accuracy, which improves
      encoder performance without hurting the quality. Also,
      as Yaowu suggested, using diamond search result as full
      search starting point and therefore adjusting(reducing)
      full search range helps the performance.
