      Rate control changes on active_worst_quality · 1e59cbf2
      Deb Mukherjee authored
      Various cleanups and refactoring.
      Removes feedback of active worst qaulity and uses last_q
      instead to make the interface cleaner. Active worst quality
      is now decided only once for a frame being coded in the
      beginning based on last_q and other stats. Also, adds other
      cleaups on last_q to store also the last_q for altref frames,
      and reduces the altref interval a little.
      
      The output does change a little.

      Enable adaptive pred filter type for sub8x8 · 3b5a90bd
      Jingning Han authored
      This commit enables an adaptive prediction filter type selection
      for sub8x8 block sizes. In speed 1, it re-uses the filter type of
      collocated 8x8 block if it is tested in the rate-distortion optimization
      loop, for the sub8x8 blocks. Otherwise, it runs the normal test
      over all the three filter types. In speed 2, it re-uses the 8x8
      block's prediction filter type, if available. Otherwise, force it
      to be EIGHTTAP.

      Further rate control cleanups · 52d27367
      Deb Mukherjee authored
      Includes various cleanups.
      Streamlines the interfaces so that all rate control state
      updates happen in the vp9_rc_postencode_update() function.
      This will hopefully make it easier to support multiple
      rate control schemes.
      Removes some unnecessary code, which in rare cases can casue
      a difference in the constrained quality mode output, but
      other than that there is no bitstream change yet.

      Modified no memory rate control. · eec3def7
      Paul Wilkins authored
      This 2-pass rate control setting allocates bits based
      on first pass stats to each kf group, gf group and individual
      frame but does not correct the bits left and allocation after
      each frame.
      
      In other words it recommends a bit allocation for each frame
      but does not try and correct any over or under spend on a
      frame over the remainder of the clip. This reduces the accuracy
      of rate control in terms of hitting an average bitrate but prevents
      problems that may arise because early frames either use to many
      or too few bits. This mode is currently more inclined to undershoot
      than overshoot (particularly at higher data rates).
      
      Also minor changes to rate of adaption when recode loop is not
      enabled.
      
      This mode is currently enabled by default for VBR.
      It gives the following % performance gains.

      Re-design rate-distortion cost tracking buffers · fc19243c
      Jingning Han authored
      This commit re-designs the per transformed block rate-distortion
      costs tracking buffers. It removes redundant buffer usage, makes
      the needed context memory allocation per VP9_COMP instance and
      reuses the same buffer sets inside the rate-distortion optimization
      search loop, thereby avoiding repeatedly requiring memory space.
      
      It reduces speed 0 runtime:
      
      bus at 2000 kbps from 166763ms to 158967ms,
      football at 600 kbps from 246614ms to 234257ms.
      
      Both about 5% speed-up. Local tests suggest about 2% to 5% speed-up
      for speed 1 and 2 settings. This does not change compression
      performance.

      Speed setting review. · 6253cc92
      Paul Wilkins authored
      Substantial reworking of the speed vs quality trade offs for
      speed 1 and 2.
      
      In this patch I am attempting to freeze the "quality" meaning of
      speeds 1 and 2 relative to speed 0 so that in future we can
      better evaluate progress.
      
      I am targeting :
      Speed 1 quality ~-5% vs speed 0.
      Speed 2 quality ~-10% vs speed 0
      
      It is inevitable that quality will still fluctuate a little as we adjust
      settings and add new features, but we will attempt to keep as
      close as possible to these values. Above speed 2 things will remain
      a bit more fluid for now.
      
      In this patch speed 1 is approximately 4-5x as fast as speed 0. This
      is similar to before but the quality hit is a lot less. Likewise speed 2
      is approximately 2x as fast as speed 1 but is similar in quality to the
      previous speed 1 configuration.
      
      Also slight change to behavior of FLAG_EARLY_TERMINATE to insure
      all reference frames get at least one rd test. Important for very low
      variance regions.
      
      WIP :- Added a new speed level with old speed 4 becoming speed 5.
      Speed 3 and 4 tradeoffs still WIP
