      Moving framerate from VP9EncoderConfig to VP9_COMP. · 5a78c406

      Framerate changes over time, VP9EncoderConfig supposed to have static
      read-only data.

      Moving pass from VP9_COMP to VP9EncoderConfig. · 91c2f1e4
      Dmitry Kovalev authored
      We had a very complicated way to initialize cpi->pass from
      cfg->g_pass:
      switch (cfg->g_pass) {
        case VPX_RC_ONE_PASS:
          oxcf->mode = ONE_PASS_GOOD;
          break;
        case VPX_RC_FIRST_PASS:
          oxcf->mode = TWO_PASS_FIRST;
          break;
        case VPX_RC_LAST_PASS:
          oxcf->mode = TWO_PASS_SECOND_BEST;
          break;
      }
      
      cpi->pass = get_pass(oxcf->mode).
      
      Now pass is moved to VP9EncoderConfig and initialization is simple:
      switch (cfg->g_pass) {
        case VPX_RC_ONE_PASS:
          oxcf->pass = 0;
          break;
        case VPX_RC_FIRST_PASS:
          oxcf->pass = 1;
          break;
        case VPX_RC_LAST_PASS:
          oxcf->pass = 2;
          break;
      }

      Common encode/decode function to get reference frame · 1ebf52df
      Adrian Grange authored
      Replaced encoder and decoder functions to get a pointer
      to a reference frame with a common function, vp9_get_ref_frame,
      and simplified it.

      Use frame index directly in get_chessboard_index · c36f78b0

      The get_chessboard_index() used to call the entire VP9_COMMON
      struct pointer to retrieve the chessboard pattern index. This cl
      makes it call the frame index directly.

      [spatial svc]Implement alt reference frames · e899859c
      Minghai Shang authored
      All changes are for spatial svc only.
      1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
      2. Use golden reference idx for spatial reference
      3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
      4. Add "auto-alt-refs" in svc options

      Decide the partitioning threshold from the variance histogram · 9d41313e
      Yunqing Wang authored
      Before encoding a frame, calculate and store each 16x16 block's
      variance of source difference between last and current frame.
      Find partitioning threshold T for the frame from its variance
      histogram, and then use T to make partition decisions.
      
      Comparing with fixed 16x16 partitioning, rtc set test showed an
      overall psnr gain of 3.242%, and ssim gain of 3.751%. The best
      psnr gain is 8.653%.
      
      The overall encoding speed didn't change much. It got faster for
      some clips(for example, 12% speedup for vidyo1), and a little
      slower for others.
      
      Also, a minor modification was made in datarate unit test.

      Skip the partition search for the frame with no motion · 12861260
      Pengchong Jin authored
      This patch allows the encoder to skip the partition search for the
      frame if it is an inter frame and only zero motion vectors have
      been detected in the first pass. The partition size is directly
      assigned according to the difference variance.
      
      Borg tests show overall little performance changes in term of PSNR
      (derf -0.027%, yt 0.152%, hd 0.078%, stdhd 0%). The worst case of
      PSNR loss is -0.514% from yt. The best PSNR gain is 4.293% from yt.
      The second pass encoding speedup for slideshow clips is 15%-40%.

      Experiment for mid group second arf. · 2e430cba
      Paul Wilkins authored
      This patch implements a mechanism for inserting a second
      arf at the mid position of arf groups.
      
      It is currently disabled by default using the flag multi_arf_enabled.
      
      Results are currently down somewhat in initial testing if
      multi-arf is enabled. Most of the loss is attributable to the
      fact that code to preserve the previous golden frame
      (in the arf buffer) in cases where we are coding an overlay
      frame, is currently disabled in the multi-arf case.

      Add static-threshold skipping in non-rd mode · b91b146d
      Yunqing Wang authored
      Added a skipping test in non-rd inter-mode. After interpolation
      prediction step, the residuals are tested to see if they will be
      quantized to 0 based on modeling between spatial domain and
      frequency domain.
      
      Set static-thresh to 800 for >=720p and 300 for <720p, rtc set
      tests showed
      1. Speed 5, psnr: -0.514%; ssim: -1.748%;
         speedup on related clips: 5% -11%
      2. Speed 6, psbr: -0.628%; ssim: -1.637%;
         speedup on related clips: 4% - 9%
