      vp9_rdopt: declare 'c' closer to use · bfd62cda
      Johann authored
      Clears up static clang analysis warning regarding a dead store. Only
      declare 'c' when it will be used.

      Fix real-time compression regression in hbd mode · 969957f9
      Jingning Han authored
      This commit resolves the compression performance regression in
      real-time encoding setting when high bit-depth mode is enabled.
      
      The current solution temporarily disables the SIMD implementations
      of vpx_satd, hadamard8x8, and hadamard16x16 in high bit-depth mode.
      
      The commit makes the coding results bit-wise identical between
      regular coding pipeline and high bit-depth at profile 0.

      vp9: Set low variance flag when partition is copied. · 0c65aed0
      Jerome Jiang authored
      Also set the flag to 1 when exit early choosing 64x64 block
      such that skipping new mv for golden works in these scenerios.
      
      Change the size of prev_segment_id to the number of superblocks
      to save memory.
      
      Borg test shows quality regression of 0.012% on average PSNR
      and 0.035% on SSIM.

      vp9: 1 pass cbr mode: increase threshold for gf_cbr_boost_pct usage. · f1909d26
      Marco authored
      Increase the boost threshold below which GOLDEN update will use same
      rate correction factor as INTER_NORMAL.
      
      Improves performance when gf_cbr_boost_pct is set (between 0 and 100)
      in CBR mode.

      vp9: Enable more aggresive short circuit for speed 8. · 267e7344
      Jerome Jiang authored
      Set short_circuit_low_temp_var to 3 for speed 8 for all res.
      No strong visual difference on all clips.

      Add support for VP9 level targeting · 337ad83e
      hui su authored
      Constraints on encoder config:
      -target_bandwidth is no larger than 80% of level bitrate limit
      -target_bandwidth * (1 + max_over_shoot_pct) is no larger than
      88% of level bitrate limit
      -min_gf_interval is no smaller than level limit
      -tile_columns is no larger than level limit
      
      Constraints on rate control:
      -current frame size plus previous three frames' size is no larger
      than the CPB level limit
      -current frame size is no larger than 50%/40%/20% of the CPB
      level limit if it's a key/alt-ref/other frame.

      vp9: Compute source sad for every superblock when partition copy is on. · afc8c483
      Jerome Jiang authored
      The source sad could be used to copy the partition without going into
      choose_partitioning function to speed up vp9 encoding. Computing source
      sad takes little time. Speed test on Android and Linux shows little
      encoding time gain (less than 1.4%).
      
      Turned off for now since partition copy is turned off.
