      vp9-svc: Fix the setting of is_key_frame. · 80a3e261
      Marco authored
      Change on affects 1 pass CBR.
      On key frame, temporal layer_id is reset to 0 for 1 pass CBR,
      but since "layer" is reset, the svc.layer_context[layer].is_key_frame
      was not correspondingly set properly.

      Changes to best quality settings. · 8ba98516
      paulwilkins authored
      Small changes to the best quality default speed trade off.
      Some speedup settings are worth while even for best quality as they
      have only a very small impact on quality but a significant impact on
      encode time.
      These changes give as much as a further 50-60% increase in encode
      speed for my test animations clip with minimal impact on quality.
      For this sequence these changes improve the best quality encode  speed
      to about the same level as good quality speed 0 in Q3 2015 whilst
      retaining the large quality gain of over 1 db
      For many natural videos though the quality difference from good 0
      to best is much smaller.

      Changes to exhaustive motion search. · 0149fb3d
      paulwilkins authored
      This change alters the nature and use of exhaustive motion search.
      Firstly any exhaustive search is preceded by a normal step search.
      The exhaustive search is only carried out if the distortion resulting
      from the step search is above a threshold value.
      Secondly the simple +/- 64 exhaustive search is replaced by a
      multi stage mesh based search where each stage has a range
      and step/interval size. Subsequent stages use the best position from
      the previous stage as the center of the search but use a reduced range
      and interval size.
      For example:
        stage 1: Range +/- 64 interval 4
        stage 2: Range +/- 32 interval 2
        stage 3: Range +/- 15 interval 1
      This process, especially when it follows on from a normal step
      search, has shown itself to be almost as effective as a full range
      exhaustive search with step 1 but greatly lowers the computational
      complexity such that it can be used in some cases for speeds 0-2.
      This patch also removes a double exhaustive search for sub 8x8 blocks
      which also contained  a bug (the two searches used different distortion
      For best quality in my test animation sequence this patch has almost
      no impact on quality but improves encode speed by more than 5X.
      Restricted use in good quality speeds 0-2 yields significant quality gains
      on the animation test of 0.2 - 0.5 db with only a small impact on encode
      speed. On most clips though the quality gain and speed impact are small.

      James Zern authored
      This reverts commit 380a5519.
      This causes an assertion failure in debug_check_frame_counts() which
      probably isn't valid with this change; leaving the investigation for
      later now.

      Add AVX vectorized vp9_diamond_search_sad · 5eefd3eb
      Geza Lore authored
      This function now has an AVX intrinsics version which is about 80%
      faster compared to the C implementation. This provides a 2-4% total
      speed-up for encode, depending on encoding parameters. The function
      utilizes 3 properties of the cost function lookup table, constructed
      in 'cal_nmvjointsadcost' and 'cal_nmvsadcosts'.
      For the joint cost:
        - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3]
      For the component costs:
        - For all i: mvsadcost[0][i] == mvsadcost[1][i]
              (equal per component cost)
        - For all i: mvsadcost[0][i] == mvsadcost[0][-i]
              (Cost function is even)
      These must hold, otherwise the AVX version of the function cannot be used.
