      Avoid allocating memory when resizing frames · c03d45de
      John Koleszar authored
      As long as the new frame is smaller than the size that was originally
      allocated, we don't need to free and reallocate the memory allocated.
      Instead, do the allocation on the size of the first frame. We could
      make this passed in from the application instead, if we wanted to
      support external upscaling.

      Merging and bug-fix in enhanced_interp experiment · 0ebf548c
      Deb Mukherjee authored
      Merged the enhanced_interp experiment.
      Found and fixed a bug in the include files framework, whereby
      certain encoder files were still using the old INTERP_EXTEND
      value of 3 instead of 4. The thresholds for mv range mcomp.c
      need a small adjustment to prevent crashes.
      
      The results are more or less unchanged.

      Removes all runtime initialization of global data. This commit is a
      squashed version of the following series cherry-picked from master.

      is a worthwhile thing to include in Eider anyway.

      WebM Experimental Codec Branch Snapshot · 6035da54
      Yaowu Xu authored
      This is a code snapshot of experimental work currently ongoing for a
      next-generation codec.
      
      The codebase has been cut down considerably from the libvpx baseline.
      For example, we are currently only supporting VBR 2-pass rate control
      and have removed most of the code relating to coding speed, threading,
      error resilience, partitions and various other features.  This is in
      part to make the codebase easier to work on and experiment with, but
      also because we want to have an open discussion about how the bitstream
      will be structured and partitioned and not have that conversation
      constrained by past work.
      
      Our basic working pattern has been to initially encapsulate experiments
      using configure options linked to #IF CONFIG_XXX statements in the
      code. Once experiments have matured and we are reasonably happy that
      they give benefit and can be merged without breaking other experiments,
      we remove the conditional compile statements and merge them in.
      
      Current changes include:
      * Temporal coding experiment for segments (though still only 4 max, it
        will likely be increased).
      * Segment feature experiment - to allow various bits of information to
        be coded at the segment level. Features tested so far include mode
        and reference frame information, limiting end of block offset and
        transform size, alongside Q and loop filter parameters, but this set
        is very fluid.
      * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used
        in MBs using 16x16 prediction modes within inter frames.
      * Compound prediction (combination of signals from existing predictors
        to create a new predictor).
      * 8 tap interpolation filters and 1/8th pel motion vectors.
      * Loop filter modifications.
      * Various entropy modifications and changes to how entropy contexts and
        updates are handled.
      * Extended quantizer range matched to transform precision improvements.
      
      There are also ongoing further experiments that we hope to merge in the
      near future: For example, coding of motion and other aspects of the
      prediction signal to better support larger image formats, use of larger
      block sizes (e.g. 32x32 and up) and lossless non-transform based coding
      options (especially for key frames). It is our hope that we will be
      able to make regular updates and we will warmly welcome community
      contributions.
      
      Please be warned that, at this stage, the codebase is currently slower
      than VP8 stable branch as most new code has not been optimized, and
      even the 'C' has been deliberately written to be simple and obvious,
      not fast.
      
      The following graphs have the initial test results, numbers in the
      tables measure the compression improvement in terms of percentage. The
      build has  the following optional experiments configured:
      --enable-experimental --enable-enhanced_interp --enable-uvintra
      --enable-high_precision_mv --enable-sixteenth_subpel_uv

      Increase chrow row alignment to 16 bytes. · 7d1b37cd
      Timothy B. Terriberry authored
      This is done by expanding luma row to 32-byte alignment, since
       there is currently a bunch of code that assumes that
       uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c,
       common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm,
       encoder/temporal_filter.c, and possibly others; I haven't done a
       full audit).
      It also uses replaces the hardcoded border of 16 in a number of
       encoder buffers with VP8BORDERINPIXELS (currently 32), as the
       chroma rows start at an offset of border/2.
      Together, these two changes have the nice advantage that simply
       dumping the frame memory as a contiguous blob produces a valid,
       if padded, image.

      Increase static linkage, remove unused functions · 429dc676
      John Koleszar authored
      A large number of functions were defined with external linkage, even
      though they were only used from within one file. This patch changes
      their linkage to static and removes the vp8_ prefix from their names,
      which should make it more obvious to the reader that the function is
      contained within the current translation unit. Functions that were
      not referenced were removed.
