      Support for extended feature flags enumeration leaf in CPUID instruction · 9f268611
      Erik Niemeyer authored
      This CL fixes an overcite with the AVX2 support CL previously
      merged (Change-Id: Idc03f3fca4bf2d0afd33631ea1d3caf8fc34ec29) that
      prevented runtime execution of AVX2 code in WebM. 
      
      Background:
      Starting with the Sandybridge processor, the CPUID instruction was
      enhanced to add various extended feature flag enumeration leaves.
      Reading these leaves requires an additional input value for the CPUID
      instruction which is stored in ECX. This change adds this second input
      value for all ARCH_X86 and ARCH_x86_64 targets to the CPUID macros,
      allowing checks of EBX bit 5 for AVX2 support. This capability will be
      required moving forward to check for future processor features.

      Use INT64_MAX instead of LLONG_MAX · 24bc1a71
      John Koleszar authored
      These variables have the type int64_t, not long long. long long could
      be a larger type than 64 bits. Emulate INT64_MAX for older versions of
      MSVC, and remove the unreferenced vpx_ports/vpxtypes.h

      silent a lot of MSVC compiler warnings · 8a336b0d
      Yaowu Xu authored
      there are still a couple type of warning left, which are related to
      double constants assigned to float type. As those would be addressed
      by the conversion of transforms into integer version. This commit
      has left those un-dealt with.

      Clean Android build defaults · d6e80deb
      Johann authored
      Disable unit-tests. The logging in GTest would need to be adjusted.
      
      Restructure ARM cpu detection. Flatten if-else logic.
      
      Change #if defined(HAVE_*) to #if HAVE_* because we only need to check
      for features that the library was actually built with. This should have
      been harmless, as disabled feature sets wouldn't have any features to
      call.

      Enables building examples with Android NDK · 5daaa838
      Attila Nagy authored
      Soft enable runtime cpu detect for armv7-android target, so that it
      can be disabled and remove dependency on 'cpufeatures' lib.
      Change the arm_cpu_caps implementation selection such that 'no rtcd' takes
      precedence over system type.
      
      Switch to use -mtune instead of -mcpu. NDK was complaining about
      -mcpu=cortex-a8 conflicting with -march=armv7-a, not sure why.
      
      Add a linker flag to fix some cortex-a8 bug, as suggested by NDK Dev
      Guide.
      
      Examples:
      Configure for armv7+neon:
      
      ./configure --target=armv7-android-gcc \
                  --sdk-path=/path/to/android/ndk \
                  --disable-runtime-cpu-detect \
                  --enable-realtime-only \
                  --disable-unit-tests
      
      ...armv7 w/o neon:
      
      ./configure --target=armv7-android-gcc \
                  --sdk-path=/path/to/android/ndk \
                  --disable-runtime-cpu-detect \
                  --enable-realtime-only \
                  --disable-neon \
                  --cpu=cortex-a9 \
                  --disable-unit-tests

      Fix pedantic compiler warnings · 0164a1cc
      John Koleszar authored
      Allows building the library with the gcc -pedantic option, for improved
      portabilty. In particular, this commit removes usage of C99/C++ style
      single-line comments and dynamic struct initializers. This is a
      continuation of the work done in commit 97b766a4, which removed most
      of these warnings for decode only builds.

      asm_*_offsets to define variables as constants · e343988f
      Alpha Lam authored
      This change is to allow obj_int_extract to extract all integers
      in the data segment. With the const keyword these variables are
      forced into the .rodata segment even for zero variable value.
      
      We had a problem before that zero valueed variables would get
      assigned to BSS segment that fooled obj_int_extract to give
      incorrect values.

      I've forward-ported it to the current version (which mostly

      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
