      New RTCD implementation · a910049a
      John Koleszar authored
      This is a proof of concept RTCD implementation to replace the current
      system of nested includes, prototypes, INVOKE macros, etc. Currently
      only the decoder specific functions are implemented in the new system.
      Additional functions will be added in subsequent commits.
      
      Overview:
        RTCD "functions" are implemented as either a global function pointer
        or a macro (when only one eligible specialization available).
        Functions which have RTCD specializations are listed using a simple
        DSL identifying the function's base name, its prototype, and the
        architecture extensions that specializations are available for.
      
      Advantages over the old system:
        - No INVOKE macros. A call to an RTCD function looks like an ordinary
          function call.
        - No need to pass vtables around.
        - If there is only one eligible function to call, the function is
          called directly, rather than indirecting through a function pointer.
        - Supports the notion of "required" extensions, so in combination with
          the above, on x86_64 if the best function available is sse2 or lower
          it will be called directly, since all x86_64 platforms implement
          sse2.
        - Elides all references to functions which will never be called, which
          could reduce binary size. For example if sse2 is required and there
          are both mmx and sse2 implementations of a certain function, the
          code will have no link time references to the mmx code.
        - Significantly easier to add a new function, just one file to edit.
      
      Disadvantages:
        - Requires global writable data (though this is not a new requirement)
        - 1 new generated source file.

      Correct clamping in use of vp8_find_near_mvs() · 83cef816
      John Koleszar authored
      Commit e06c242b introduced a change to call vp8_find_near_mvs() only
      once instead of once per reference frame by observing that the only
      effect that the frame had was on the bias applied to the motion
      vector. By keeping track of the sign_bias value, the mv to use could
      be flip-flopped by multiplying its components by -1.
      
      This behavior was subtley wrong in the case when clamping was applied
      to the motion vectors found by vp8_find_near_mvs(). A motion vector
      could be in-bounds with one sign bias, but out of bounds after
      inverting the sign, or vice versa. The clamping must match that done
      by the decoder.
      
      This change modifies vp8_find_near_mvs() to remove the clamping from
      that function. The vp8_pick_inter_mode() and vp8_rd_pick_inter_mode()
      functions instead track the correctly clamped values for both bias
      values, switching between them by simple assignment. The common
      clamping and inversion code is in vp8_find_near_mvs_bias()

      Revert "Multithreaded encoder, late sync loopfilter" · 630d3b95
      John Koleszar authored
      This commit is incomplete, as it does not synchronize the loop filter
      before returning a handle to the reconstructed frame in
      vpx_codec_get_preview_frame(), which can cause (false?) failures
      when running the test_reconstruct_buffer test.
      
      This may be related to a bug that does cause visible artifacts, which
      is also under investigation.
      
      This reverts commit 380d64ec.

      Disconnect ARM tgt_isa from dsp extensions · 89210284
      Fritz Koenig authored
      A processor with ARMv7 instructions does not
      necessarily have NEON dsp extensions.  This CL
      has the added side effect of allowing the ability
      to enable/disable the dsp extensions cleanly.

      Fixed bugs in multi-layer code related to changing params · e479379a
      Adrian Grange authored
      When running multi-layer (ML) encodes and dynamically
      changing coding parameters on the fly (e.g. frame
      duration/rate, bandwidths allocated to each layer)
      the encoder would not produce sensible output.
      
      In certain cases the rate targeting would be
      hideously inaccurate.
      
      These fixes make it possible to change these coding
      parameters correctly and to maintain accurate control
      of the rate targeting.
      
      I also added the specification of the input timebase
      into the test program, vp8_scalable_patterns.c.

      Remove unnecessary ternary constructs · 0c2b2c79
      John Koleszar authored
      The code had a number of constructs like (condition)?1:0,
      which is redundant with C's semantics. In the cases where a boolean
      operator was used in the condition, simply remove the ternary part.
      Otherwise adjust the surrounding expression to remove the condition
      (eg, for rounding up. See pickinter.c and rdopt.c)

      Avoid heap allocation of firstpass stats · 26c6a44c
      John Koleszar authored
      The total_stats, this_frame_stats, and total_left_stats structures
      were previously create by a heap allocation, despite being of fixed
      size. These structures were allocated and deallocated during
      {de,}allocate_compressor_data, which is reinvoked whenever the frame
      size changes. Unfortunately, this clobbers the total_stats and
      total_left_stats data.
      
      Historically, these were variable size at one time, due to the first
      pass motion map, which necessitated their being created by a unique
      heap allocation. However, this bug with the total_stats being
      clobbered has probably been present since that initial implementation.
      
      These structures are instead moved to be stored within the struct
      twopass_rc directly, rather than being heap allocated separately.

      Only call vp8_find_near_mvs() once for each macroblock · e06c242b
      Yunqing Wang authored
      While doing motion search on a macroblock, we usually call
      vp8_find_near_mvs once per reference frame. Actually, for
      different reference frames, the only difference in calculating
      these near_mvs is they may have different sign_bias, which
      causes a sign change in resulting near_mvs. In this change, we
      only do find_near_mvs for the first reference frame. For other
      reference frames, only need to adjust the near_mvs according to
      that reference frame's sign_bias value.
