      [CFL] Alpha signaling · f533400a
      Luc Trudeau authored
      Writes and reads alpha to and from the bitstream.
      
      A special case is needed on the encoder side to handle prediction block
      skips. Since whether or not a prediction block is skipped during CfL, a
      rollback is required if the block was skipped and the alpha index was
      not zero. The advantage of this is that no signaling is required when
      the prediction block is skipped as it is assumed tha the alpha index is
      zero.
      
      A encode facade is added to the intra prediction facade as CfL requires
      special encoder side operations.

      [CFL] Load luma as prediction for chroma · baeb3758
      Luc Trudeau authored
      Loads the stored reconstructed luma pixels for each trasnform block
      inside a prediction block. Supports 4:4:4 and 4:2:0 chroma subsampling
      modes.
      
      The CFL_CTX struct is now in cfl.h with appropriate forward declarations

      [CFL] Store luma as prediction for chroma · e3980281
      Luc Trudeau authored
      Stores the reconstructed luma pixels for each transform block inside a
      prediction block. Rectangular transform blocks are supported.
      
      As for RDO, after all the modes have been tested for luma, an extra
      encoding is perform in order to store the reconstructed pixel values of
      the best mode. These values are then used for RDO on the chromatic
      planes.

      [CFL] Custom block-level DC_PRED · f8164157
      Luc Trudeau authored
      Adds the CfL experiment flag and computes a block-level DC_PRED that is
      required by CfL in order to compute alpha_cb and alpha_cr.
      
      The rate-distorsion impact of computing DC_PRED at the prediction block level
      for chroma planes is rather small

      Adding video reader/writer APIs. · 37e6fd3d
      Dmitry Kovalev authored
      Right now only IVF format is supported which is enough for example code.
      Other formats like y4m, webm, raw yuv will be supported later.

      vpx[dec|enc]: Extract IVF support from the apps. · 00a35aab
      Tom Finegan authored
      - Move IVF reading support into ivfdec.c and ivfdec.h
      - Move IVF writing support into ivfenc.c and ivfenc.h
      - Removed IVF writing code from the SVC example in favor of ivfenc.

      Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB. · 4a0f9478
      Dmitry Kovalev authored
      Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
      them with one constant. Inlining appropriate arguments for functions:
        vp9_cond_prob_diff_update (encoder)
        vp9_diff_update_prob (decoder)

      cosmetics: trim trailing whitespace · 94c52e4d
      John Koleszar authored
      When the license headers were updated, they accidentally contained
      trailing whitespace, so unfortunately we have to touch all the files
      again.
