      combine loopfilter data access · 3556deac
      Johann authored
      The data processed by the loopfilter overlaps. At the block level, this
      results in some redundant transforms. Grouping the filtering allows for
      a single 16x16 transpose (and inversion) instead of three 16x8 transposes
      (and three more inversions).
      
      This implementation is x86_64 only. We retain the previous
      implementation for x86.
      
      Improvements are obviously material dependant, but it seems to be ~%1 in
      tests here.

      Call vp8_find_near_mvs lazily · 7bce513a
      Alpha Lam authored
      vp8_find_near_mvs() is being called on all possible reference frames
      but the data computed may be used if the loop exits early, which can
      be due to x->skip beign set to 1.
      
      Optimize this by call vp8_find_near_mvs() laziy only if it is going
      to be used and not computed yet.

      CQ and two pass rate control. · b6e27d5f
      Paul Wilkins authored
      Changes to the selection of Q limits for two pass
      and two pass CQ mode.
      
      Allowance made for Mode and motion vector costs.
      Some refactoring of common code.
      
      For Derf and YT sets CQ mode average improvement
      circa 1% (SSIM and Global PSNR).
      
      Some increased tendency to undershoot even when
      user CQ not reached.
      
      Patch2: Removed some test code accidentally merged.

      makefile: fix target 'all' · 22ea8592
      John Koleszar authored
      'all' is the conventional target for building everything in the
      makefile, but the child make was expecting all-$(target), for debugging
      reasons that I don't recall exactly. Restore the expected behavior.

      Multithreaded encoder, late sync loopfilter · 380d64ec
      Attila Nagy authored
      Sync with loopfilter thread just at the beginning of next frame encoding.
      This returns control to application faster and allows a better multicore scaling.
      When PSNR packets are generated the final filtered frame is needed imediatly
      so we cannot delay the sync.

      Fix necessary for input partitions iface to match the RTP profile · e529a825
      Stefan Holmer authored
      These changes fixes a glitch between the RTP profile and the input
      partitions interface. Since there's no way for the user to know the
      actual number of partitions, the decoder have to read the
      multi_token_paritition bits also when input partitions mode is
      enabled.
      
      Included are also a couple of fixes for issues with independent
      partitions and uninitialized memory reads.

      Tero Rintaluoma authored
      Modified original patch If2f07220885c4c3a0cae0dace34ea0e36124f001
      according to comments. Scheduled code a little bit to prevent some
      interlocks.
