      Adaptive motion control on ref and search range · a4ce53f1
      Jingning Han authored
      This commit takes a preliminary attempt to refine the motion search
      control. It detects the SAD associated with mv predictor per reference
      frame, and based on which to determine whether the encoder wants to
      reduce the motion search range (if the predicted mv provides fairly
      small SAD), or to skip the current reference frame (if there exists
      another ref frame that gives much smaller SAD cost).
      
      This feature is turned on in the settings of speed 1 and above.

      Remove redundant function and calls · ed90a176
      Yaowu Xu authored
      lf deltas are later setup in function vp9_setup_past_independence(),
      so this commit removed the redundant copy. Also renamed a function
      to better align the behavior of the funciton.

      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.
      derfraw300: +0.224% (global psnr)
      stdhdraw250: +0.442% (global psnr)
