      Accumulate EXT_TX counts for multithread · 325b96dc
      Peter de Rivaz authored
      EXT_TX introduces some new symbols to be decoded.
      The encoder counts how many times these are used.
      In multithreaded mode, the counts from the worker threads
      need to be accumulated into the main thread.
      
      This change means that VP10/VPxEncoderThreadTest now works
      with more choices of cpu-used and number of passes.

      Fix merge defects · 5a27b3bb
      Yaowu Xu authored
      This commit fixes the merge conflicts between master and nextgenv2 and
      disable early termination in choose_tx_size() to avoid failure in test.
      
      The test failures are pre-existing, some of the issue were fixed in
      masterbase already, so will have another merge to introduce the fixes.

      vp10: clip MVs before adding to find_ref_mvs() list. · 293e20df
      Ronald S. Bultje authored
      This causes the output of find_ref_mvs() to always be unique or zero.
      A nice side-effect of this is that it also causes the output of
      find_ref_mvs_sub8x8() to be unique-or-zero, and it will not ignore
      available candidate MVs under certain conditions.
      
      See issue 1012.

      vp10: allow MV refs to point outside visible image. · dea99899
      Ronald S. Bultje authored
      In VP9, the ref MV had to point to a block that itself fully resided
      within the visible image, i.e. all borders of the image had to be
      within the visible borders of the coded frame. This is somewhat
      illogical, and had obscure side effects, e.g. clamping of fairly
      reasonable motion vectors such as 0,0 were clipped to negative values
      if the block was overhanging on frame edges (such as the last rows
      on 1080p content), which makes no sense whatsoever.
      
      Instead, relax clamping constraints such that the ref MVs are allowed
      to point to blocks exactly outside the visible edges in both Y as well
      as UV planes, including the 8tap filter edges (that's why the offset is
      8 pixels + block size).
      
      See issue 1037.

      - real-world default probabilities
      - why is counts sometimes NULL in the decoder? Does that mean bw
        adaptivity updates only work on some frames? (I haven't looked
        very closely yet, maybe this is a red herring.)

      vp10: remove ref-MV-dependent use of HP. · 1799f2f8
      Ronald S. Bultje authored
      This change (in a new config experiment: universal_hp) removes the
      bitstream parsing dependency of the HP MV bit on the ref MV to be
      coded. It also cleans up clearing of the HP bit in near/nearestMV,
      since HP is always on if it's set in the frame header.
      
      This admittedly doesn't clean up the crap that could be cleaned up,
      but that's mostly because I think this needs some careful review;
      not so much for coding style, but more from hardware people and from
      the codec team on what we/you want. It would also be nice to get some
      actual numbers on the real quality impact of this change. If, for
      example, hardware people come up and tell us they don't actually care
      anymore, we should probably just this code as-is and do nothing (i.e.
      discard this patch).

      This actually has no effect whatsoever, since the input MVs themselves
      are clamped by clamp_mv_ref() already, which is significantly more
      restrictive in its bounds.

      Adds an early termination to the ext_tx search, and also

      There is a 0.09% drop in performance on derflr from 1.735% to
      1.648%, but worth it with the speedup achieved.

      Rename display_{size,width,height} to render_*. · 36ffe644
      Ronald S. Bultje authored
      The name "display_*" (or "d_*") is used for non-compatible information
      (that is, the cropped frame dimensions in pixels, as opposed to the
      intended screen rendering surface size). Therefore, continuing to use
      display_* would be confusing to end users. Instead, rename the field
      to render_*, so that struct vpx_image can include it.

      In practice, this fixes the issue that if you have an odd number of

      will be skipped over odd cols as well as odd rows (because it holds a
      single variable for both edges).
