      Re-worked header files · b962646f
      Scott LaVarnway authored
      Various header/test files had to be re-worked in order to
      build "Remove cm parameter from vp9_decode_block_tokens()".
      
      This patch reverts the "Remove cm" part and only contains
      the re-worked header files.

      Add encoder control for setting color space · e94b415c
      Yaowu Xu authored
      This commit adds encoder side control for vp9 to set color space info
      in the output compressed bitstream.
      
      It also amends the "vp9_encoder_params_get_to_decoder" test to verify
      the correct color space information is passed from the encoder end to
      decoder end.

      Change the use of a reserved color space entry · af3519a3
      Yaowu Xu authored
      This commit rename a reserved color space entry to BT_2020, it intends
      to provide support for VP9 bitstream to pass along the color space
      type defined in BT.2020(Rec.2020)
      
      please note this entry does not have any effect on encoding/decoding
      behavior, but allow applications to the pass the information along
      from encoding end to decoding end.

      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.

      High-level hooks for Profile 2 (10/12 bit) · d35df2d8
      Deb Mukherjee authored
      Adds some high-level hooks for profile 2 before further
      progress on the implementation.
      
      According to the definitiion in this patch:
      1. Profile 2 only supports 10 or 12 bit color but not 8
      2. Profile 2 supports all color sampling modes: 444, 422 and 420,
      and alpha plane.
      3. Profile 3 is currently undefined.
      
      Please consider the definition carefully and suggest modifications
      to the definition as needed.

      Change to limit the mv search range · c4048dbd
      Yaowu Xu authored
      As the pixel values beyond image border are duplicates of pixels
      on edge, the change limits the mv search range, any mv beyond
      the limits no longer produce new/different prediction values
      as entire block with pixels used for subpel interpolation are
      outside image border.

      Adding ss_size_lookup table. · 8db2675b
      Dmitry Kovalev authored
      Removing the old one bsize_from_dim_lookup. Now we have a way to determine
      block size for plane using its subsampling values (ss_size_lookup). And
      then we can find the number of pixels in the block (num_pels_log2_lookup).

      Some minor cleanups for efficiency · 94c481f9
      Deb Mukherjee authored
      Implements some of the helper functions more efficiently with
      lookups rathers than branches. Modeling function is consolidated
      to reduce some computations.
      
      Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into
      one because there is no need to keep them separate (even though
      the semantics are a little different).
      
      No bitstream or output change.
      
      About 0.5% speedup

      Enable recursive partition down to 4x4 · 1f26840f
      Jingning Han authored
      This commit allows the rate-distortion optimization recursion
      at encoder to go down to 4x4 block size. It deprecates the use
      of I4X4_PRED and SPLITMV syntax elements from bit-stream
      writing/reading. Will remove the unused probability models in
      the next patch.
      
      The partition type search and bit-stream are now capable of
      supporting the rectangular partition of 8x8 block, i.e., 8x4
      and 4x8. Need to revise the rate-distortion parts to get these
      two partition tested in the rd loop.

      Add joint motion search in comp_inter_inter mode(experiment) · 9f5811c2
      Yunqing Wang authored
      In current code, motion vectors got from single prediction mode are used
      in compound prediction mode directly. These motion vectors may not give
      accurate prediction since they are searched independently. In this patch,
      we took Pascal's suggestion, and did joint motion search in compound
      prediction mode to find better motion vectors in this situation.
      Test results:
      Overall PSNR: 0.570%(derf), 0.918%(stdhd);
      SSIM: 0.572%(derf), 1.009%(stdhd);
      
      The encoder is a little slower. This can be improved since some c
      code is used in motion search.

      Extend left/above partition context to per mi(8x8) · 4a88ad89
      Jingning Han authored
      Update and buffer left/above partition information context per 8x8
      block. This allows to further enable recursive partition down to
      4x4 block size, and hence deprecating I4X4_PRED and SPLITMV.
      
      This commit also fixes a context buffer swap/restore issue in 32x32
      partition type search. This gives 0.1% performance gain for derf/yt.
      Will refactor the superblock partition type search into recursion
      form.
