      vp9/10: improve support for render_width/height. · 812945a8
      Ronald S. Bultje authored
      In the decoder, map this to the output variable vpx_image_t.r_w/h.
      This is intended as an improved version of VP9D_GET_DISPLAY_SIZE,
      which doesn't work with parallel frame decoding. In the encoder,
      map this to a codec control func (VP9E_SET_RENDER_SIZE) that takes
      a w/h pair argument in a int[2] (identical to VP9D_GET_DISPLAY_SIZE).
      
      Also add render_size to the encoder_param_get_to_decoder unit test.
      
      See issue 1030.

      Add support for color-range. · eeb5ef0a
      Ronald S. Bultje authored
      In decoder, export (eventually) into vpx_image_t.range field. In
      encoder, use oxcf->color_range to set it (same way as for
      color_space).
      
      See issue 1059.

      Enable decoder to pass through color space info · 6b223fcb
      Yaowu Xu authored
      This commit added a field to vpx_image_t for indicating color space,
      the field is also added to YUV_BUFFER_CONFIG. This allows the color
      space information pass through the decoder from input stream to the
      output buffer.
      
      The commit also updated compare_img() function with added verification
      of matching color space to ensure the color space information to be
      correctly passed from encode to decoder in compressed vp9 streams.

      Frank Galligan authored
      Add support for setting byte alignment on the Y, U, and V plane of the
      reference buffers. The byte alignment must be a power of 2, from 32 to
      1024. A value of 0 sets legacy alignment.

      Adds config opt for highbitdepth + misc. vpx · 5acfafb1
      Deb Mukherjee authored
      Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
      Also includes most vpx level high bit-depth functions. However
      encode/decode in the highbitdepth profiles will not work until
      the rest of the code is in place.

      Add get release decoder frame buffer functions. · e8e15279
      Frank Galligan authored
      This CL changes libvpx to call a function when a frame buffer
      is needed for decode. Libvpx will call a release callback when
      no other frames reference the frame buffer. This CL adds a
      default implementation of the frame buffer callbacks. Currently
      only VP9 is supported. A future CL will add support for
      applications to supply their own frame buffer callbacks.

      Increase border size from 96 to 160. · b02c4d36
      Ronald S. Bultje authored
      This is required because upon downscaling, if a motion vector points
      partially into the UMV (e.g. all minus 1 of 64+7 pixels, i.e. 70),
      then we can point up to 140 pixels into the larger-resolution (2x)
      reference buffer UMV, which means the UMV for reference buffers in
      downscaling needs to be 140 rounded up to the nearest multiple of 32,
      i.e. 160.
      
      Longer-term, we should probably handle the UMV differently by detecting
      edge coverage on-the-fly and using a temporary buffer for edge extensions
      instead of adding 160 pixels on all sides of the image (which means a
      CIF image uses 3x its own area size for borders).

      Subsampling aware allocs and bitstream · da58436f
      John Koleszar authored
      Make framebuffer allocations according to the chroma subsamping
      factors in use. A bit is placed in the raw part of the frame header for
      each of the two subsampling factors. This will be moved in a future
      commit to make them part of the TBD feature set bits, probably only set
      on keyframes, etc.

      Expand UMV border to 96 pixels · 9f5fd31d
      John Koleszar authored
      Ensures that the full 64 pixel border is available for prediction (need a minimum of
      64+INTERP_EXTEND on all sides, and 32+INTERP_EXTEND on UV). Value also must be a
      multiple of 32 to keep UV stride alignment. The smaller border was causing the prediction
      to read outside the frame, which can cause a mismatch.
      
      TODO: Get rid of this explicit border and use edge emulation instead.

      Fix pulsing issue with scaling · 9b7be888
      John Koleszar authored
      Updates the YV12_BUFFER_CONFIG structure to be crop-aware. The
      exiting width/height parameters are left unchanged, storing the
      width and height algined to a 16 byte boundary. The cropped
      dimensions are added as new fields.
      
      This fixes a nasty visual pulse when switching between scaled and
      unscaled frame dimensions due to a mismatch between the scaling
      ratio and the 16-byte aligned sizes.

      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

      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.

      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
