      Refactor selected partition size coding for rtc · 1fc0bde6
      Jingning Han authored
      This commit makes a refactoring of the rtc_use_partition. It allows
      the encoder to take a preferred block size for non-RD mode decision.
      The boundary blocks are handled such that smaller block sizes that
      fit in the boundary size will be used instread.
      
      In rtc mode, the coding performance of speed -6 for pedestrian_1080p
      goes from
      158980 b/f, 38.934 dB, 22721 ms to
      159008 b/f, 40.064 dB, 23721 ms.
      
      For rtc set, the speed -6 compression performance is improved by
      26%. Still about 2dB behind speed -5 at this point.

      Removed the reset of mode_info from previous frame · 896d79a5
      Yaowu Xu authored
      Prior to this commit, both encoder and decoder reset mode/mv info from
      previous frame in error resilient mode to ensure bitstreams are able to
      decode when there is loss of frame in decoder side. However, this is
      not necessary. This commit changed to remove the reset, so encoder can
      continue to use mode/mv/partition information from previously encoded
      frame without affecting decodeablilty under loss of frame.

      Initialize internal buffer pointers in rtc mode · cc10ee0a
      Jingning Han authored
      In rtc coding mode, the encoder is running non-RD mode decision. It
      does not need dual buffer swap as was the case in the RD mode. This
      commit initializes the internal buffer pointers outside the block
      coding loop for rtc mode.

      Remove redundant set_offsets in rtc coding mode · 4712877e
      Jingning Han authored
      The functionalities of set_offsets() are subsumed in later
      set_partitioning() and rtc_use_partition() functions, hence removed.

      Enable encode_breakout in real time encoding · 507fd522
      Yunqing Wang authored
      In real time encoding, we enable encode_breakout to make encoding
      fast. A speed feature "use_encode_breakout" is defined to set
      encode_breakout thresholds for different speeds.
      
      However, currently, static_thresh is an encoder option. The encode_
      breakout can be turned off if user sets static_thresh=0 specifically.
      
      The rtc set borg test result: (need to set --static_thresh=1)
      speed -5, psnr loss -3.543%;
      speed -4, psnr loss -2.358%;
      speed -3, psnr loss -0.771%.
      
      Encoding speed test:
      speed -5, 11% - 60% speedup;
      speed -4, 5.5% - 28% speedup;
      speed -3, 0.8% - 7% speedup.

      Modified Aq1 and Aq2 · f30b3231
      Paul Wilkins authored
      Aq 1 only updates segment map on kf and arf and
      only uses 3 segments. With these settings AQ1 is
      + for most clips in SSIM but negative in psnr.
      However, the penalty in PSNR is much less than
      previously.
      
      Old version aq1 average results for std hd
      -20.899% psnr, -5.809% SSIM
      New version aq1 for std hd
      -3.57% psnr, +1.23% SSIM
      
      Aq2 Now uses only 2 segments and rd.
      This mode is still slightly negative for most clips on
      psnr and SSIM but seems to have a much bigger visual
      impact on several problem clips than aq mode 1.
      
      Old results for std hd:
      -2.578% psnr, -1.151% SSIM
      New results for std hd:
      -1.561% psnr, -0.85% SSIM

      Merged two similar functions to reduce duplication · 855070e2
      Yaowu Xu authored
      Function encode_rtc_frame_internal() and encode_frame_internal() only
      differed by a couple of speed features, this commit relocation those
      difference into the setup of speed features and merged two functions
      into one to remove duplication.
      
      It also fixed a subtle bug super_fast_rtc was used before it was
      initialized.

      Only allow interp_filter change in SWITCHABLE mode · 538b1c6d
      Yaowu Xu authored
      This commit added a logic to prevent the inter_filter type from being
      changed if the default interp_filter mode is not switchable. Also, it
      sets the default interp_filter to BILINEAR at very and super fast rtc
      encoding modes
