      Added an experiment "bidir_pred" for backward prediction · cf5083d4
      Zoe Liu authored
      Major parts have been implemented as follows:
      (1) Added BRF_UPDATE, LASTNRF_UPDATE, and NRF_UPDATE in firstpass.c;
      (2) Added the handling for the scenario of
      "cpi->common.show_existing_frame == 1" at the encoder;
      (3) Added a new reference frame of BWDREF_FRAME;
      (4) Have bwd-ref work with upsampled references.
      
      Note that when the experiment of "ext_refs" turned on, this experiment
      will be turned off automatically currently.
      
      RD performance in Overall PSNR has been improved, compared against the
      VP10 baseline:
      
      lowres: Avg -3.312; BDRate -3.154
      derflr: Avg -1.927; BDRate -1.176
      midres: Avg -2.149; BDRate -2.001
      hdres : Avg -0.567; BDRate -0.588

      vp10: fix encoder crash on flush · a7beb23d
      James Zern authored
      cherry-picked from libvpx:
      4f780e94 vp9/10: fix encoder crash on flush
      
      the lookahead buffer allocation is deferred to receipt of the first
      frame to allow profile changes. if the encoder was flushed before
      supplying any frames the encoder would crash trying to dereference the
      NULL buffer.

      Add support for setting byte alignment. · 399823b6
      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.

      Make last frame source available in current frame encoding · 4a9928e5
      Yunqing Wang authored
      While encoding a frame, its last frame source can be used to give
      acurate motion information. This patch prevents last frame to be
      overwritten so that it is available during current frame encoding.
      
      The last source is scaled when it is necessary. cpi->Last_Source
      points to the last source frame.

      Enables alt-ref frames in one pass mode · 50bf8fd4
      Deb Mukherjee authored
      Includes a few fixes and clean-ups that adds the ability
      to use alt-ref frames in one-pass mode.
      Whether alt-refs are actually used or not is controlled by a
      macro USE_ALTREF_FOR_ONE_PASS in vp9_firstpass.c.
      
      This first cut seems to improve derf by 15+% in 1-pass mode.
      But further experiments with parameters are underway.

      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.

      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.

      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.
