      Implement Chroma-from-Luma (#492) · 1e639ba3
      David Michael Barr authored
      * Add the chroma-from-luma predictor and a test
      * Add benchmarks for CfL predictor
      * Implement CfL signalling
      * Plumb from predict_intra to pred_cfl
      * Add struct for CfL parameters
      * Compute subsampled luma AC and plumb it with CfL alpha
      * Plumb CfL parameters up to RDO
      * Add CfL to RDO loop, no parameter search

      Add basic support for nonzero motion vectors (#485) · 83fcc030
      fbossen authored
      * Add motion vector paramater to inter prediction function
      Motion vector is read from added data field in Block structure
      * Add reference frame and motion vector fields/parameters
      Reference frame and motion vector are added fields to the
      RDOOutput structure and added parameters to the block
      encoding function
      * Fix inter prediction function for nonzero MVs
      * Add call to encode new motion vector
      * Import default cdfs for MV coding from libaom
      * Fix handling of MV precision in MV coding function
      * Add coding of DRL mode
      * Add motion vector stack
      * Add new MV counter to correctly determine context
      * Use motion vectors in MV stack for prediction
      * Sort MV stack according to weights
      Also update weights after near search
      * Fix log2() function
      * Compute correct context for DRL flag
      * Store MVs with 1/8 pel precision and fix MV generation
      * Add some basic motion estimation
      Motion estimation is full search (+/-16 pel range in 2-pel increments) and
      is done independently for each block
      * Fix chroma motion compensation for small blocks
      Chroma motion compensation sometimes happens on 2x2 basis

      Re-eliminate pkg-config dependency under MinGW · 15c25de5
      Andrew D'Addesio authored and Thomas Daede's avatar Thomas Daede committed
      On MinGW, the "no_build_target(cfg!(windows))" line unfortunately
      prevents out/lib/pkgconfig/aom.pc from being created, causing the
      "// MSVC" code branch to be taken which results in a linker error
      (-laom not found).
      Rather than fixing pkg-config, we can pass an absolute path to
      libaom.a like we already do to aom.lib for MSVC. This has the
      benefit that rav1e can be compiled with MinGW directly from cmd,
      where pkg-config usually isn't available.
      Tested on:
      * MinGW-Builds 8.1.0 (cmd, msys2 terminal)
      * Visual Studio 2017 15.8.1 (cmd, msys2 terminal)

      Test skip on and off in RDO loop (#474) · c2d7b6af
      fbossen authored
      * Refactor RDO loop to avoid code duplication
      Use same code regardless of whether a loop over chroma modes
      is needed
      * Test skip on and off in RDO loop
      * Don't search transform type when skipping
      * Don't try to skip when using intra modes
      * Fix issues with speed 0 and speed 1
      Handling of < 8x8 was incorrect in CDEF and in reset_skip_context()
      * Use dense sampling for chroma components in above_coeff_context and left_coeff_context

      Enable mixing intra and inter blocks in inter frames (#469) · bf537275
      fbossen authored and Thomas Daede's avatar Thomas Daede committed
      * WIP motion vector reference search
      * More searches
      * Have a version that compiles
      * Actually call MV prediction function
      Fix a few bugs along the way
      * Add computation of context for inter mode
      * Have find_mvrefs return a mode_context value and use it
      * Test but never select intra mode in inter frame
      * Fixes to context derivation for inter mode
      Some success with mixing intra and inter in a same frame but
      still buggy
      * Fixes to find MV references functions
      Can encode/decode 20 frames at speed 4, but not at slower speed
      * Fix MV scan
      Now intra/inter mixing works for all speed settings
      * Fix issues that arose from rebase
      * Remove lines that should not have been added
      * Remove superfluous empty lines
      * Supress compiler warnings
      * A few cosmetic improvements
