      vp9 SVC: Fix the denoiser frame buffer management. · 0f8ebdde
      Jerome Jiang authored
      Change the denoiser frame buffer management for SVC to more generally
      handle the layer patterns in SVC (where last is not always refreshed).
      This change is only for SVC with denoising and is bitexact.

      vp9: Fix to SVC and denoising for fixed pattern case. · 3818a372
      Marco authored
      For fixed pattern SVC: keep track of denoised last_frame buffer
      for base temporal layer, and if alt_ref is updated on middle/upper
      temporal layers, force an update to denoised last_frame buffer.
      This allows for improved denoising on top temporal layers.

      vp9: Remove alt-ref from denoiser. · 2ac7c549
      Jerome Jiang authored
      Denoiser is used in real-time mode which does not use alt-ref.
      Reduce memory usage when denoiser is enabled.

      vp9: Fix some issues with denoiser and SVC. · a340c64a
      Marco authored
      Fix the update of the denoiser buffer when the base
      spatial layer is a key frame. And allow for better/lower
      QP on high spatial layers when their base layer is key frame.

      vp9: Incorporate source sum_diff into non-rd partition thresholds. · 7f2daa74
      Marco authored
      Increase the variance partition thresholds for superblocks that
      have low sum-diff (from source analysis prior to encoding frame).
      Use it for now only for speed >= 7 or for denoising on.
      Small change on metrics for rtc set: less than ~0.1 avgPNSR decrease
      on RTC set, for both speed 7 and 8.

      Move the logic for rechecking zeromv on denoised block out to simplify

      VP9_PICKMODE_CTX_DEN which is only used when denoiser is enabled.

      vp9-denoiser: Avoid copy-block when denoising is at LowLow level. · ac86dde3
      Marco authored
      Avoid copy-block when denoising is at LowLow level (i.e., no denoising is done).
      Instead, don't enter denoiser at all, and when level goes back up over kLowLow
      do a reset in denoiser.

      vp9 denoiser: Re-evaluate ZEROMV after denoiser filtering. · 5b0ddb93
      Marco authored
      For denoising, and for noise level above threshold, re-evaluate
      ZEROMV for mode selection after denoising.
      Current change only does this check if selected best mode (before denoising)
      was intra.

      Move noise level estimate outside denoiser. · c7da053d
      Marco authored
      Source noise level estimate is also useful for
      setting variance encoder parameters (variance thresholds,
      qp-delta, mode selection, etc), so allow it to be used also
      if denoising is not on.

      Temporary fix to denoiser when dynamic resizing is on.

      Add SSE2 code and unit test for VP9 denoiser. · 80465dae
      JackyChen authored
      This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are
      only 16x16 blocks in denoiser, while in VP9, there are 13 different
      block sizes.
      By adding this SSE2 code, the improvement of encoder speed is around
      20%(using C code vs using SSE2 code), vary for different clips.
      The unit test for VP9 denoiser is to confirm that the SSE2 code is
      bit-exact with the C code. The unit test covers all block size.

      Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
      Also includes most vpx level high bit-depth functions. However
      encode/decode in the highbitdepth profiles will not work until
      the rest of the code is in place.

      VP9 Denoiser denoises after mode/bsize search · 03819ed9
      Tim Kopp authored
      In vp8, statistics are collected about the different modes as they are searched.
      This process is more complicated due to the variable block size. Fields were
      added to the PICM_MODE_CONTEXT struct to hold this information for each point in
      the search. The information is then taken from the appropriate part of the tree
      during denoising.
