      EXT_INTER experiment · 1ac85879
      Yue Chen authored
      NEW2MV is enabled, representing a new motion vector predicted from
      NEARMV. It is mostly ported from nextgen, where it was named
      NEW_INTER.
      A few fixes are done for sub8x8 RDO to correct some misused
      mv references in the original patch.
      A 'bug-fix' for encoding complexity is done, reducing the additional
      encoding time from 50% to 20%. In sub8x8 case, the old patch
      did motion search for every interpolation filter (vp9 only
      searches once). This fix also slightly improves the coding gain.
      This experiment has been made compatible with REF_MV and EXT_REFS.
      
      Coding gain (derflr/hevcmr/hevchd): 0.267%/0.542%/0.257%

      Make encoder buffer allocation dynamic · 3807dd82
      Adrian Grange authored
      Frame buffers are now allocated dynamically on-demand.
      
      Entries in the reference frame map, cm->ref_frame_map,
      may now be set to -1 (INVALID_IDX) to indicate that
      there is not a valid reference buffer in that "slot".
      
      All slots in the reference frame map are now initialized
      to the empty state (-1) and each buffer is initialized
      to have a reference count of 0.

      Enable sub8x8 inter block search for RTC coding mode · dad89d5c
      Jingning Han authored
      This commit enables sub8x8 inter block coding for RTC mode. The
      use of sub8x8 blocks can be turned on by allowing
      choose_partitioning function to select 4x4/4x8/8x4 block sizes.

      vp9_ethread: modify VP9_COMP structure · edbd61e1
      Yunqing Wang authored
      This patch modified struct VP9_COMP. Created a struct ThreadData
      to include data that need to be copied for each thread. In
      multiple thread case, one thread processes one tile. all threads
      share one copy of VP9_COMP,
      (refer to VP9_COMP *cpi in the code)
      but each thread has its own copy of ThreadData,
      (refer to ThreadData *td in the code).
      Therefore, within the scope of encode_tiles(), both cpi and td
      need to be passed as function parameters.
      
      In single thread case, the FRAME_COUNTS pointer in ThreadData
      points to "counts" in VP9_COMMON.

      vp9_ethread: move filter_cache out of RD_OPT struct · 379334c2

      Similar to mask_filter, the filter_cache in RD_OPT struct can be
      moved out, and declared as a local variable since it is only
      used in pick_inter_mode functions.

      Refactor rate distortion cost structure · 811cef97
      Jingning Han authored
      This commit makes a struct that contains rate value, distortion
      value, and the rate-distortion cost. The goal is to provide a
      better interface for rate-distortion related operation. It is
      first used in rd_pick_partition and saves a few RDCOST calculations.

      This commit allows the non-RD mode decision flow to  select
      prediction filter type in NEWMV mode. It provides 8.14% compression
      performance gains in both settings of AQ=0 and 3. The current speed
      impact is about 5% to 10% slower.

      Use modeled rate distortion costs for non-RD mode · 539c961e
      Jingning Han authored
      This commit replaces SAD cost with modeled rate-distortion cost
      for non-RD mode decision. It translates the prediction residual
      SSE into estimate rate and reconstruction distorion costs, hence
      capturing the quantization setting effect. The compression
      performance of speed -7 for rtc set is improved by 14.79%.
