      Remove i4x4_pred. · 1efa79d3
      Ronald S. Bultje authored
      It remains as a local define in rdopt.c so we can distinguish between
      split and non-split modes in the RD loop, but disappears outside that
      scope in the codec.

      Patch to remove implicit segmentation. · 1b103f25
      Paul Wilkins authored
      This patch removes the implicit segmentation
      experiment from the code base as the benefits
      were still unproven as of the bitstream deadline.

      Moved use_prev_in_find_mv_refs check to frame level · 353642bc
      Scott LaVarnway authored
      This patch checks at the frame level to see if the previous
      mode info context can be used.  This patch eliminates the
      flag check that was done for every mode and removes another
      check that was done prior to every vp9_find_mv_refs().

      a few clean-ups · 2b96ffe0
      Yaowu Xu authored
      1. remove prediction mode conversion
      2. unified bmode, same for key and non-key frame
      3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer
      coded ever. It is determined by ref_frame and block partition

      Reduce bmi buffer length from 16 to 4 · de735929
      Jingning Han authored
      This commit removes the use of bmi_ in the first-pass encoding by
      forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT
      only, as John suggested. This makes the need for bmi buffer only
      up to 4 entries, instead of 16.

      Change txfm_type decision · 22694ca1
      Yaowu Xu authored
      The changing in intra coding to base on transform block, i.e. pred->
      txfm->quant->dequant-itxfm->recon, made all blocks within a prediction
      unit behave consistently, there is no longer a need to handle blocks
      differently based on the position within a predicitn block. So this
      commit simplifies the decision of transform type to be based on
      prediction mode only.

      Merge 4x4 block level partition into codebase · 7ac5ac52
      Jingning Han authored
      Move 4x4/4x8/8x4 partition coding out of experimental list.
      
      This commit fixed the unit test failure issues. It also resolved
      the merge conflicts between 4x4 block level partition and iterative
      motion search for comp_inter_inter.

      changes intra coding to be based on txfm block · 8ba92a0b
      Yaowu Xu authored
      This commit changed the encoding and decoding of intra blocks to be
      based on transform block. In each prediction block, the intra coding
      iterates thorough each transform block based on raster scan order.
      
      This commit also fixed a bug in D135 prediction code.
      
      TODO next:
      The RD mode/txfm_size selection should take this into account when
      computing RD values.

      WIP: 4x4 idct/recon merge · ba48a111
      Scott LaVarnway authored
      This patch eliminates the intermediate diff buffer usage by
      combining the short idct and the add residual into one function.
      The encoder can use the same code as well.

      Enable bit-stream support to 8x4 and 4x8 partition · 810b612c
      Jingning Han authored
      The recursive partition type search is enabled down to 4x4, 4x8 and
      8x4, followed by the corresponding rate-distortion optimization for
      the per-partition encoding mode decisions.
      
      The bit-stream writing/reading synchronized in supporting the
      rectangular partition of 8x8 block.
      
      This provides above 1% coding performance gains on derf.
      
      To do next:
      1. re-design the rate-distortion loop for inter prediction below 8x8.
      2. re-design the rate-distortion loop for intra prediction below 4x4.
      3. make the loop-filter aware of rectangular partition of 8x8 block.
      4. clean the unused probability models.
      5. update default probability values.

      Initial version of alpha channel support · 679e4abd
      John Koleszar authored
      This is a mostly-working implementation of an extra channel in the
      bitstream. Configure with --enable-alpha to test. Notable TODOs:
      
       - Add extra channel to all mismatch tests, PSNR, SSIM, etc
       - Configurable subsampling
       - Variable number of planes (currently always uses all 4)
       - Loop filtering
       - Per-plane lossless quantizer
       - ARNR support
      
      This implementation just uses the same contents as the Y channel
      for the A channel, due to lack of content and general pain in
      playing back 4 channel content. A later patch will use the actual
      alpha channel passed in from outside the codec.

      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.

      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.

      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.
