      vpxdec: Fix webm fps check. · a9e00cd4
      Frank Galligan authored
      If the webm file did not have a Cues then vpxdec would fail
      when creating a y4m file. If there is no Cues element print
      out a warning and set fps to 30.

      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.

      WebM Experimental Codec Branch Snapshot · 6035da54
      Yaowu Xu authored
      This is a code snapshot of experimental work currently ongoing for a
      next-generation codec.
      
      The codebase has been cut down considerably from the libvpx baseline.
      For example, we are currently only supporting VBR 2-pass rate control
      and have removed most of the code relating to coding speed, threading,
      error resilience, partitions and various other features.  This is in
      part to make the codebase easier to work on and experiment with, but
      also because we want to have an open discussion about how the bitstream
      will be structured and partitioned and not have that conversation
      constrained by past work.
      
      Our basic working pattern has been to initially encapsulate experiments
      using configure options linked to #IF CONFIG_XXX statements in the
      code. Once experiments have matured and we are reasonably happy that
      they give benefit and can be merged without breaking other experiments,
      we remove the conditional compile statements and merge them in.
      
      Current changes include:
      * Temporal coding experiment for segments (though still only 4 max, it
        will likely be increased).
      * Segment feature experiment - to allow various bits of information to
        be coded at the segment level. Features tested so far include mode
        and reference frame information, limiting end of block offset and
        transform size, alongside Q and loop filter parameters, but this set
        is very fluid.
      * Support for 8x8 transform - 8x8 dct with 2nd order 2x2 haar is used
        in MBs using 16x16 prediction modes within inter frames.
      * Compound prediction (combination of signals from existing predictors
        to create a new predictor).
      * 8 tap interpolation filters and 1/8th pel motion vectors.
      * Loop filter modifications.
      * Various entropy modifications and changes to how entropy contexts and
        updates are handled.
      * Extended quantizer range matched to transform precision improvements.
      
      There are also ongoing further experiments that we hope to merge in the
      near future: For example, coding of motion and other aspects of the
      prediction signal to better support larger image formats, use of larger
      block sizes (e.g. 32x32 and up) and lossless non-transform based coding
      options (especially for key frames). It is our hope that we will be
      able to make regular updates and we will warmly welcome community
      contributions.
      
      Please be warned that, at this stage, the codebase is currently slower
      than VP8 stable branch as most new code has not been optimized, and
      even the 'C' has been deliberately written to be simple and obvious,
      not fast.
      
      The following graphs have the initial test results, numbers in the
      tables measure the compression improvement in terms of percentage. The
      build has  the following optional experiments configured:
      --enable-experimental --enable-enhanced_interp --enable-uvintra
      --enable-high_precision_mv --enable-sixteenth_subpel_uv

      Multiframe quality enhancement postprocessing · 87aa846b
      Deb Mukherjee authored
      Adds a multiframe postprocessing module to enhance the quality of
      certain frames that are coded at lower quality than preceding frames.
      The module can be invoked from the commandline by use of the --mfqe
      option, and will be most beneficial for enhancing the quality of
      frames decoded using scalable patterns.
      
      Uses the vp8_variance_var16x16 and vp8_variance_sad16x16 function
      pointers to compute SAD and Variance of blocks.

      Adding error-concealment to the decoder. · d04f8523
      Stefan Holmer authored
      The error-concealer is plugged in after any motion vectors have been
      decoded. It tries to estimate any missing motion vectors from the
      motion vectors of the previous frame. Intra blocks with missing
      residual are replaced with inter blocks with estimated motion vectors.
      
      This feature was developed in a separate sandbox
      (sandbox/holmer/error-concealment).

      Adds "armvX-none-rvct" targets · 11a222f5
      Tero Rintaluoma authored
      Adds following targets to configure script to support RVCT compilation
      without operating system support (for Profiler or bare metal images).
       - armv5te-none-rvct
       - armv6-none-rvct
       - armv7-none-rvct
      
      To strip OS specific parts from the code "os_support"-config was added
      to script and CONFIG_OS_SUPPORT flag is used in the code to exclude OS
      specific parts such as OS specific includes and function calls for
      timers and threads etc. This was done to enable RVCT compilation for
      profiling purposes or running the image on bare metal target with
      Lauterbach.
      
      Removed separate AREA directives for READONLY data in armv6 and neon
      assembly files to fix the RVCT compilation. Otherwise
      "ldr <reg>, =label" syntax would have been needed to prevent linker
      errors. This syntax is not supported by older gnu assemblers.
