      Enable skipping reference frame check in rd loop · d66c7486
      Jingning Han authored
      This commit allows encoder to compare the SAD cost associated with
      the best motion vector predictor, per frame. If one reference frame
      has this cost more than 4 times of the best SAD cost given by other
      reference frames, skip NEARESTMV, NEARMV, ZEROMV mode check of this
      reference frame.
      
      This setting is turned on in speed 2 and above. Compression quality
      change in speed 2:
      derf  -0.014%
      yt    -0.097%
      hd    -0.023%
      stdhd  0.046%
      
      It reduces the speed 2 runtime of test sequences:
      pedestrian_area_1080p 4000 kbps 310763 ms -> 303595 ms
      bluesky_1080p 6000 kbps         259852 ms -> 251920 ms

      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.
      
      Compression and speed performance wise:
      speed 1

      Yaowu Xu authored
      In evaluating partition split case, Wrong partition size is used in
      calling partition_plane_context(). This commit change to use the
      correct sub partition size. The incorrect partition size used were
      causing an ASAN error in unit test.

      Moving eob array to the encoder. · f00d157c
      Dmitry Kovalev authored
      In the decoder we don't need to save eobs, we can pass eob as an argument.
      That's why removing eob arrays from VP9Decompressor and TileWorkerData,
      and moving eob pointer from macroblockd_plane to macroblock_plane.

      In frame Q adjustment experiment. · 644bd87e
      Paul Wilkins authored
      The idea here is to allow "in frame" adjustment of the final Q
      value used to encode each SB64, using segmentation.
      
      There is also adjustment of the rd mult in regions of overspend.
