      Trying to make encode_sb() more similar to write_modes_sb() and

      Disable early exit based on distortion in lossless · f8c06fb2
      Yaowu Xu authored
      In lossless coding, distortion is always 0. Early exit based on this
      metric was incorrect.
      This CL also changed to use best_rd instead of distortion as the metric
      for easly exit as requested by Jim.

      Full range motion search for regular block sizes · b295092b
      Jingning Han authored
      Add a full range motion search for regular block sizes. This runs
      exhaustive search within the given reference area. This commit further
      optimizes the search process by combining 4 points test into one
      pipeline, which gives 30% speed-up as compared to run each individual
      point at a time.
      This full range search serves as a best possible motion search reference.
      When replacing the diamond search with full range search, the speed 0
      runtime of bus CIF at 2000 kbps goes from 153872ms to 623051ms. The
      compression performance compared to speed 0 setting gains 0.585% for
      derf set.

      Remove rate correction factor. · 570b6d25
      Paul Wilkins authored
      Removed an adaptive rate correction factor that was having
      a negative impact on quality in many clips. This factor
      was influencing the Q range available to each frame
      independently of the bits allocated to each.

      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.
