-2016-07-20 v1.6.0 "Khaki Campbell Duck"
-  This release improves upon the VP9 encoder and speeds up the encoding and
-  decoding processes.
-
-  - Upgrading:
-    This release is ABI incompatible with 1.5.0 due to a new 'color_range' enum
-    in vpx_image and some minor changes to the VP8_COMP structure.
-
-    The default key frame interval for VP9 has changed from 128 to 9999.
-
-  - Enhancement:
-    A core focus has been performance for low end Intel processors. SSSE3
-    instructions such as 'pshufb' have been avoided and instructions have been
-    reordered to better accommodate the more constrained pipelines.
-
-    As a result, devices based on Celeron processors have seen substantial
-    decoding improvements. From Indian Runner Duck to Javan Whistling Duck,
-    decoding speed improved between 10 and 30%. Between Javan Whistling Duck
-    and Khaki Campbell Duck, it improved another 10 to 15%.
-
-    While Celeron benefited most, Core-i5 also improved 5% and 10% between the
-    respective releases.
-
-    Realtime performance for WebRTC for both speed and quality has received a
-    lot of attention.
-
-  - Bug Fixes:
-    A number of fuzzing issues, found variously by Mozilla, Chromium and others,
-    have been fixed and we strongly recommend updating.
-

-
-  - Bug Fixes:
-    A variety of fuzzing issues
-
-2015-04-03 v1.4.0 "Indian Runner Duck"
-  This release includes significant improvements to the VP9 codec.
-
-  - Upgrading:
-    This release is ABI incompatible with 1.3.0. It drops the compatibility
-    layer, requiring VPX_IMG_FMT_* instead of IMG_FMT_*, and adds several codec
-    controls for VP9.
-
-  - Enhancements:
-    Faster VP9 encoding and decoding
-    Multithreaded VP9 decoding (tile and frame-based)
-    Multithreaded VP9 encoding - on by default

-    files.
-
-  - Known Issues:
-    Frame Parallel decoding fails for segmented and non-420 files.
-
-2013-11-15 v1.3.0 "Forest"
-  This release introduces the VP9 codec in a backward-compatible way.
-  All existing users of VP8 can continue to use the library without
-  modification. However, some VP8 options do not map to VP9 in the same manner.
-
-  The VP9 encoder in this release is not feature complete. Users interested in
-  the encoder are advised to use the git master branch and discuss issues on
-  libvpx mailing lists.
-
-  - Upgrading:

-      In general, quality is consistent with the Eider release.
-
-  - Bug Fixes:
-      This release represents approximately a year of engineering effort,
-      and contains multiple bug fixes. Please refer to git history for details.
-
-
-2012-12-21 v1.2.0
-  This release acts as a checkpoint for a large amount of internal refactoring
-  and testing. It also contains a number of small bugfixes, so all users are
-  encouraged to upgrade.
-
-  - Upgrading:
-    This release is ABI and API compatible with Duclair (v1.0.0). Users
-    of older releases should refer to the Upgrading notes in this
-    document for that release.
-
-  - Enhancements:

-
-      Minor tweaks to ARNR filtering
-      Minor improvements to real time encoding with multiple temporal layers
-
-  - Bug Fixes:
-      Fixes multithreaded encoder race condition in loopfilter
-      Fixes multi-resolution threaded encoding
-      Fix potential encoder dead-lock after picture resize
-
-
-2012-05-09 v1.1.0 "Eider"
-  This introduces a number of enhancements, mostly focused on real-time
-  encoding. In addition, it fixes a decoder bug (first introduced in
-  Duclair) so all users of that release are encouraged to upgrade.
-
-  - Upgrading:
-    This release is ABI and API compatible with Duclair (v1.0.0). Users
-    of older releases should refer to the Upgrading notes in this
-    document for that release.
-
-    This release introduces a new temporal denoiser, controlled by the
-    VP8E_SET_NOISE_SENSITIVITY control. The temporal denoiser does not
-    currently take a strength parameter, so the control is effectively
-    a boolean - zero (off) or non-zero (on). For compatibility with
-    existing applications, the values accepted are the same as those
-    for the spatial denoiser (0-6). The temporal denoiser is enabled
-    by default, and the older spatial denoiser may be restored by
-    configuring with --disable-temporal-denoising. The temporal denoiser
-    is more computationally intensive than the spatial one.
-
-    This release removes support for a legacy, decode only API that was
-    supported, but deprecated, at the initial release of libvpx
-    (v0.9.0). This is not expected to have any impact. If you are
-    impacted, you can apply a reversion to commit 2bf8fb58 locally.
-    Please update to the latest libvpx API if you are affected.
-
-  - Enhancements:
-      Adds a motion compensated temporal denoiser to the encoder, which
-      gives higher quality than the older spatial denoiser. (See above
-      for notes on upgrading).
-
-      In addition, support for new compilers and platforms were added,
-      including:
-        improved support for XCode
-        Android x86 NDK build
-        OS/2 support
-        SunCC support
-
-      Changing resolution with vpx_codec_enc_config_set() is now
-      supported. Previously, reinitializing the codec was required to
-      change the input resolution.
-
-      The vpxenc application has initial support for producing multiple
-      encodes from the same input in one call. Resizing is not yet
-      supported, but varying other codec parameters is. Use -- to
-      delineate output streams. Options persist from one stream to the
-      next.
-
-      Also, the vpxenc application will now use a keyframe interval of
-      5 seconds by default. Use the --kf-max-dist option to override.
-
-  - Speed:
-      Decoder performance improved 2.5% versus Duclair. Encoder speed is
-      consistent with Duclair for most material. Two pass encoding of
-      slideshow-like material will see significant improvements.
-
-      Large realtime encoding speed gains at a small quality expense are
-      possible by configuring the on-the-fly bitpacking experiment with
-      --enable-onthefly-bitpacking. Realtime encoder can be up to 13%
-      faster (ARM) depending on the number of threads and bitrate
-      settings. This technique sees constant gain over the 5-16 speed
-      range. For VC style input the loss seen is up to 0.2dB. See commit
-      52cf4dca for further details.
-
-  - Quality:
-      On the whole, quality is consistent with the Duclair release. Some
-      tweaks:
-
-        Reduced blockiness in easy sections by applying a penalty to
-        intra modes.
-
-        Improved quality of static sections (like slideshows) with
-        two pass encoding.
-
-        Improved keyframe sizing with multiple temporal layers
-
-  - Bug Fixes:
-      Corrected alt-ref contribution to frame rate for visible updates
-      to the alt-ref buffer. This affected applications making manual
-      usage of the frame reference flags, or temporal layers.
-
-      Additional constraints were added to disable multi-frame quality
-      enhancement (MFQE) in sections of the frame where there is motion.
-      (#392)
-
-      Fixed corruption issues when vpx_codec_enc_config_set() was called
-      with spatial resampling enabled.
-
-      Fixed a decoder error introduced in Duclair where the segmentation
-      map was not being reinitialized on keyframes (#378)
-
-
-2012-01-27 v1.0.0 "Duclair"
-  Our fourth named release, focused on performance and features related to
-  real-time encoding. It also fixes a decoder crash bug introduced in
-  v0.9.7, so all users of that release are encouraged to upgrade.
-
-  - Upgrading:
-      This release is ABI incompatible with prior releases of libvpx, so the
-      "major" version number has been bumped to 1. You must recompile your
-      applications against the latest version of the libvpx headers. The
-      API remains compatible, and this should not require code changes in most
-      applications.
-
-  - Enhancements:
-      This release introduces several substantial new features to the encoder,
-      of particular interest to real time streaming applications.
-
-      Temporal scalability allows the encoder to produce a stream that can
-      be decimated to different frame rates, with independent rate targetting
-      for each substream.
-
-      Multiframe quality enhancement postprocessing can make visual quality
-      more consistent in the presence of frames that are substantially
-      different quality than the surrounding frames, as in the temporal
-      scalability case and in some forced keyframe scenarios.
-
-      Multiple-resolution encoding support allows the encoding of the
-      same content at different resolutions faster than encoding them
-      separately.
-
-  - Speed:
-      Optimization targets for this release included the decoder and the real-
-      time modes of the encoder. Decoder speed on x86 has improved 10.5% with
-      this release. Encoder improvements followed a curve where speeds 1-3
-      improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved
-      1.5% to 10.5%, respectively. "Best" mode speed is consistent with the
-      Cayuga release.
-
-  - Quality:
-      Encoder quality in the single stream case is consistent with the Cayuga
-      release.
-
-  - Bug Fixes:
-      This release fixes an OOB read decoder crash bug present in v0.9.7
-      related to the clamping of motion vectors in SPLITMV blocks. This
-      behavior could be triggered by corrupt input or by starting
-      decoding from a P-frame.
-
-
-2011-08-15 v0.9.7-p1 "Cayuga" patch 1
-  This is an incremental bugfix release against Cayuga. All users of that
-  release are strongly encouraged to upgrade.
-
-    - Fix potential OOB reads (cdae03a)
-
-          An unbounded out of bounds read was discovered when the
-          decoder was requested to perform error concealment (new in
-          Cayuga) given a frame with corrupt partition sizes.
-
-          A bounded out of bounds read was discovered affecting all
-          versions of libvpx. Given an multipartition input frame that
-          is truncated between the mode/mv partition and the first
-          residiual paritition (in the block of partition offsets), up
-          to 3 extra bytes could have been read from the source buffer.
-          The code will not take any action regardless of the contents
-          of these undefined bytes, as the truncated buffer is detected
-          immediately following the read based on the calculated
-          starting position of the coefficient partition.
-
-    - Fix potential error concealment crash when the very first frame
-      is missing or corrupt (a609be5)
-
-    - Fix significant artifacts in error concealment (a4c2211, 99d870a)
-
-    - Revert 1-pass CBR rate control changes (e961317)
-      Further testing showed this change produced undesirable visual
-      artifacts, rolling back for now.
-
-
-2011-08-02 v0.9.7 "Cayuga"
-  Our third named release, focused on a faster, higher quality, encoder.
-
-  - Upgrading:
-    This release is backwards compatible with Aylesbury (v0.9.5) and
-    Bali (v0.9.6). Users of older releases should refer to the Upgrading
-    notes in this document for that release.
-
-  - Enhancements:
-          Stereo 3D format support for vpxenc
-          Runtime detection of available processor cores.
-          Allow specifying --end-usage by enum name
-          vpxdec: test for frame corruption

-          Generate a vpx.pc file for pkg-config.
-          New ways of passing encoded data between encoder and decoder.
-
-  - Speed:
-      This release includes across-the-board speed improvements to the
-      encoder. On x86, these measure at approximately 11.5% in Best mode,
-      21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6).
-      On ARM Cortex A9 with Neon extensions, real-time encoding of video
-      telephony content is 35% faster than Bali on single core and 48%
-      faster on multi-core. On the NVidia Tegra2 platform, real time
-      encoding is 40% faster than Bali.
-
-      Decoder speed was not a priority for this release, but improved
-      approximately 8.4% on x86.
-
-          Reduce motion vector search on alt-ref frame.
-          Encoder loopfilter running in its own thread

-          Reduce unnecessary distortion computation
-          Use diamond search to replace full search
-          Preload reference area in sub-pixel motion search (real-time mode)
-
-  - Quality:
-      This release focused primarily on one-pass use cases, including
-      video conferencing. Low latency data rate control was significantly
-      improved, improving streamability over bandwidth constrained links.
-      Added support for error concealment, allowing frames to maintain
-      visual quality in the presence of substantial packet loss.
-

-
-2011-03-07 v0.9.6 "Bali"
-  Our second named release, focused on a faster, higher quality, encoder.
-
-  - Upgrading:
-    This release is backwards compatible with Aylesbury (v0.9.5). Users

-      query decoder to determine which reference frames were updated
-      implemented error tracking in the decoder
-      fix pipe support on windows
-
-  - Speed:
-      Primary focus was on good quality mode, speed 0. Average improvement
-      on x86 about 40%, up to 100% on user-generated content at that speed.
-      Best quality mode speed improved 35%, and realtime speed 10-20%. This
-      release also saw significant improvement in realtime encoding speed
-      on ARM platforms.
-
-        Improved encoder threading

-      also includes support for "activity masking," which greatly improves
-      SSIM at the expense of PSNR. For now, this feature is available with
-      the --tune=ssim option. Further experimentation in this area
-      is ongoing. This release also introduces a new rate control mode

-
-
-2010-10-28 v0.9.5 "Aylesbury"
-  Our first named release, focused on a faster decoder, and a better encoder.
-
-  - Upgrading:
-    This release incorporates backwards-incompatible changes to the
-    ivfenc and ivfdec tools. These tools are now called vpxenc and vpxdec.
-
-    vpxdec
-      * the -q (quiet) option has been removed, and replaced with
-        -v (verbose). the output is quiet by default. Use -v to see
-        the version number of the binary.
-
-      * The default behavior is now to write output to a single file
-        instead of individual frames. The -y option has been removed.
-        Y4M output is the default.
-
-      * For raw I420/YV12 output instead of Y4M, the --i420 or --yv12
-        options must be specified.
-
-          $ ivfdec -o OUTPUT INPUT
-          $ vpxdec --i420 -o OUTPUT INPUT
-
-      * If an output file is not specified, the default is to write
-        Y4M to stdout. This makes piping more natural.
-
-          $ ivfdec -y -o - INPUT | ...
-          $ vpxdec INPUT | ...
-
-      * The output file has additional flexibility for formatting the
-        filename. It supports escape characters for constructing a
-        filename from the width, height, and sequence number. This
-        replaces the -p option. To get the equivalent:
-
-          $ ivfdec -p frame INPUT
-          $ vpxdec --i420 -o frame-%wx%h-%4.i420 INPUT
-
-    vpxenc
-      * The output file must be specified with -o, rather than as the
-        last argument.
-
-          $ ivfenc <options> INPUT OUTPUT
-          $ vpxenc <options> -o OUTPUT INPUT
-
-      * The output defaults to webm. To get IVF output, use the --ivf
-        option.
-
-          $ ivfenc <options> INPUT OUTPUT.ivf
-          $ vpxenc <options> -o OUTPUT.ivf --ivf INPUT
-
-
-  - Enhancements:
-      ivfenc and ivfdec have been renamed to vpxenc, vpxdec.
-      vpxdec supports .webm input
-      vpxdec writes .y4m by default
-      vpxenc writes .webm output by default
-      vpxenc --psnr now shows the average/overall PSNR at the end
-      ARM platforms now support runtime cpu detection
-      vpxdec visualizations added for motion vectors, block modes, references
-      vpxdec now silent by default
-      vpxdec --progress shows frame-by-frame timing information
-      vpxenc supports the distinction between --fps and --timebase
-      NASM is now a supported assembler

-/* ChangeLog for this library:
- *
- * NDK r10e?: Add MIPS MSA feature.
- *
- * NDK r10: Support for 64-bit CPUs (Intel, ARM & MIPS).
- *
- * NDK r8d: Add android_setCpu().
- *
- * NDK r8c: Add new ARM CPU features: VFPv2, VFP_D32, VFP_FP16,
- *          VFP_FMA, NEON_FMA, IDIV_ARM, IDIV_THUMB2 and iWMMXt.
- *
- *          Rewrite the code to parse /proc/self/auxv instead of
- *          the "Features" field in /proc/cpuinfo.
- *
- *          Dynamically allocate the buffer that hold the content
- *          of /proc/cpuinfo to deal with newer hardware.
- *
- * NDK r7c: Fix CPU count computation. The old method only reported the
- *           number of _active_ CPUs when the library was initialized,
- *           which could be less than the real total.
- *
- * NDK r5: Handle buggy kernels which report a CPU Architecture number of 7
- *         for an ARMv6 CPU (see below).
- *
- *         Handle kernels that only report 'neon', and not 'vfpv3'
- *         (VFPv3 is mandated by the ARM architecture is Neon is implemented)
- *
- *         Handle kernels that only report 'vfpv3d16', and not 'vfpv3'
- *
- *         Fix x86 compilation. Report ANDROID_CPU_FAMILY_X86 in
- *         android_getCpuFamily().
- *
- * NDK r4: Initial release

- * Technical note: Making sense of ARM's FPU architecture versions.
- *
- * FPA was ARM's first attempt at an FPU architecture. There is no Android
- * device that actually uses it since this technology was already obsolete
- * when the project started. If you see references to FPA instructions
- * somewhere, you can be sure that this doesn't apply to Android at all.
- *
- * FPA was followed by "VFP", soon renamed "VFPv1" due to the emergence of
- * new versions / additions to it. ARM considers this obsolete right now,
- * and no known Android device implements it either.
- *
- * VFPv2 added a few instructions to VFPv1, and is an *optional* extension
- * supported by some ARMv5TE, ARMv6 and ARMv6T2 CPUs. Note that a device
- * supporting the 'armeabi' ABI doesn't necessarily support these.
- *
- * VFPv3-D16 adds a few instructions on top of VFPv2 and is typically used
- * on ARMv7-A CPUs which implement a FPU. Note that it is also mandated
- * by the Android 'armeabi-v7a' ABI. The -D16 suffix in its name means
- * that it provides 16 double-precision FPU registers (d0-d15) and 32
- * single-precision ones (s0-s31) which happen to be mapped to the same
- * register banks.
- *
- * VFPv3-D32 is the name of an extension to VFPv3-D16 that provides 16
- * additional double precision registers (d16-d31). Note that there are
- * still only 32 single precision registers.
- *
- * VFPv3xD is a *subset* of VFPv3-D16 that only provides single-precision
- * registers. It is only used on ARMv7-M (i.e. on micro-controllers) which
- * are not supported by Android. Note that it is not compatible with VFPv2.
- *
- * NOTE: The term 'VFPv3' usually designate either VFPv3-D16 or VFPv3-D32
- *       depending on context. For example GCC uses it for VFPv3-D32, but
- *       the Linux kernel code uses it for VFPv3-D16 (especially in
- *       /proc/cpuinfo). Always try to use the full designation when
- *       possible.
- *
- * NEON, a.k.a. "ARM Advanced SIMD" is an extension that provides
- * instructions to perform parallel computations on vectors of 8, 16,
- * 32, 64 and 128 bit quantities. NEON requires VFPv32-D32 since all
- * NEON registers are also mapped to the same register banks.
- *
- * VFPv4-D16, adds a few instructions on top of VFPv3-D16 in order to
- * perform fused multiply-accumulate on VFP registers, as well as
- * half-precision (16-bit) conversion operations.
- *
- * VFPv4-D32 is VFPv4-D16 with 32, instead of 16, FPU double precision
- * registers.
- *
- * VPFv4-NEON is VFPv4-D32 with NEON instructions. It also adds fused
- * multiply-accumulate instructions that work on the NEON registers.
- *
- * NOTE: Similarly, "VFPv4" might either reference VFPv4-D16 or VFPv4-D32
- *       depending on context.
- *
- * The following information was determined by scanning the binutils-2.22
- * sources:
- *
- * Basic VFP instruction subsets:
- *
- * #define FPU_VFP_EXT_V1xD 0x08000000     // Base VFP instruction set.
- * #define FPU_VFP_EXT_V1   0x04000000     // Double-precision insns.

- * #define FPU_VFP_EXT_V3   0x00800000     // VFPv3 double-precision.
- * #define FPU_NEON_EXT_V1  0x00400000     // Neon (SIMD) insns.
- * #define FPU_VFP_EXT_D32  0x00200000     // Registers D16-D31.

-/* The list of feature flags for ANDROID_CPU_FAMILY_ARM that can be
- * recognized by the library (see note below for 64-bit ARM). Value details
- * are:
- *
- *   VFPv2:
- *     CPU supports the VFPv2 instruction set. Many, but not all, ARMv6 CPUs
- *     support these instructions. VFPv2 is a subset of VFPv3 so this will
- *     be set whenever VFPv3 is set too.
- *
- *   ARMv7:
- *     CPU supports the ARMv7-A basic instruction set.
- *     This feature is mandated by the 'armeabi-v7a' ABI.
- *
- *   VFPv3:
- *     CPU supports the VFPv3-D16 instruction set, providing hardware FPU
- *     support for single and double precision floating point registers.
- *     Note that only 16 FPU registers are available by default, unless
- *     the D32 bit is set too. This feature is also mandated by the
- *     'armeabi-v7a' ABI.
- *
- *   VFP_D32:
- *     CPU VFP optional extension that provides 32 FPU registers,
- *     instead of 16. Note that ARM mandates this feature is the 'NEON'
- *     feature is implemented by the CPU.
- *
- *   NEON:
- *     CPU FPU supports "ARM Advanced SIMD" instructions, also known as
- *     NEON. Note that this mandates the VFP_D32 feature as well, per the
- *     ARM Architecture specification.
- *
- *   VFP_FP16:
- *     Half-width floating precision VFP extension. If set, the CPU
- *     supports instructions to perform floating-point operations on
- *     16-bit registers. This is part of the VFPv4 specification, but
- *     not mandated by any Android ABI.
- *
- *   VFP_FMA:
- *     Fused multiply-accumulate VFP instructions extension. Also part of
- *     the VFPv4 specification, but not mandated by any Android ABI.
- *
- *   NEON_FMA:
- *     Fused multiply-accumulate NEON instructions extension. Optional
- *     extension from the VFPv4 specification, but not mandated by any
- *     Android ABI.
- *
- *   IDIV_ARM:
- *     Integer division available in ARM mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   IDIV_THUMB2:
- *     Integer division available in Thumb-2 mode. Only available
- *     on recent CPUs (e.g. Cortex-A15).
- *
- *   iWMMXt:
- *     Optional extension that adds MMX registers and operations to an
- *     ARM CPU. This is only available on a few XScale-based CPU designs
- *     sold by Marvell. Pretty rare in practice.
- *
- *   AES:
- *     CPU supports AES instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   CRC32:
- *     CPU supports CRC32 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   SHA2:
- *     CPU supports SHA2 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   SHA1:
- *     CPU supports SHA1 instructions. These instructions are only
- *     available for 32-bit applications running on ARMv8 CPU.
- *
- *   PMULL:
- *     CPU supports 64-bit PMULL and PMULL2 instructions. These
- *     instructions are only available for 32-bit applications
- *     running on ARMv8 CPU.
- *
- * If you want to tell the compiler to generate code that targets one of
- * the feature set above, you should probably use one of the following
- * flags (for more details, see technical note at the end of this file):
- *
- *   -mfpu=vfp
- *   -mfpu=vfpv2
- *     These are equivalent and tell GCC to use VFPv2 instructions for
- *     floating-point operations. Use this if you want your code to
- *     run on *some* ARMv6 devices, and any ARMv7-A device supported
- *     by Android.
- *
- *     Generated code requires VFPv2 feature.
- *
- *   -mfpu=vfpv3-d16
- *     Tell GCC to use VFPv3 instructions (using only 16 FPU registers).
- *     This should be generic code that runs on any CPU that supports the
- *     'armeabi-v7a' Android ABI. Note that no ARMv6 CPU supports this.
- *
- *     Generated code requires VFPv3 feature.
- *
- *   -mfpu=vfpv3
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers.
- *     Generated code requires VFPv3|VFP_D32 features.
- *
- *   -mfpu=neon
- *     Tell GCC to use VFPv3 instructions with 32 FPU registers, and
- *     also support NEON intrinsics (see <arm_neon.h>).
- *     Generated code requires VFPv3|VFP_D32|NEON features.
- *
- *   -mfpu=vfpv4-d16
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA features.
- *
- *   -mfpu=vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32 features.
- *
- *   -mfpu=neon-vfpv4
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|NEON|NEON_FMA
- *     features.
- *
- *   -mcpu=cortex-a7
- *   -mcpu=cortex-a15
- *     Generated code requires VFPv3|VFP_FP16|VFP_FMA|VFP_D32|
- *                             NEON|NEON_FMA|IDIV_ARM|IDIV_THUMB2
- *     This flag implies -mfpu=neon-vfpv4.
- *
- *   -mcpu=iwmmxt
- *     Allows the use of iWMMXt instrinsics with GCC.
- *
- * IMPORTANT NOTE: These flags should only be tested when
- * android_getCpuFamily() returns ANDROID_CPU_FAMILY_ARM, i.e. this is a
- * 32-bit process.
- *
- * When running a 64-bit ARM process on an ARMv8 CPU,
- * android_getCpuFeatures() will return a different set of bitflags

-Description:
-x264/libav's framework for x86 assembly. Contains a variety of macros and
-defines that help automatically allow assembly to work cross-platform.
-
-Local Modifications:
-Get configuration from vpx_config.asm.
-Prefix functions with vpx by default.
-Manage name mangling (prefixing with '_') manually because 'PREFIX' does not
-  exist in libvpx.
-Expand PIC default to macho64 and respect CONFIG_PIC from libvpx
-Set 'private_extern' visibility for macho targets.
-Copy PIC 'GLOBAL' macros from x86_abi_support.asm
-Use .text instead of .rodata on macho to avoid broken tables in PIC mode.
-Use .text with no alignment for aout
-Only use 'hidden' visibility with Chromium

-; Macros to eliminate most code duplication between x86_32 and x86_64:
-; Currently this works only for leaf functions which load all their arguments
-; into registers at the start, and make no other use of the stack. Luckily that
-; covers most of x264's asm.
-
-; PROLOGUE:
-; %1 = number of arguments. loads them from stack if needed.
-; %2 = number of registers used. pushes callee-saved regs if needed.
-; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
-; %4 = (optional) stack size to be allocated. The stack will be aligned before
-;      allocating the specified stack size. If the required stack alignment is
-;      larger than the known stack alignment the stack will be manually aligned
-;      and an extra register will be allocated to hold the original stack
-;      pointer (to not invalidate r0m etc.). To prevent the use of an extra
-;      register as stack pointer, request a negative stack size.
-; %4+/%5+ = list of names to define to registers
-; PROLOGUE can also be invoked by adding the same options to cglobal
-
-; e.g.
-; cglobal foo, 2,3,7,0x40, dst, src, tmp
-; declares a function (foo) that automatically loads two arguments (dst and
-; src) into registers, uses one additional register (tmp) plus 7 vector
-; registers (m0-m6) and allocates 0x40 bytes of stack space.
-
-; TODO Some functions can use some args directly from the stack. If they're the
-; last args then you can just not declare them, but if they're in the middle
-; we need more flexible macro.
-
-; RET:
-; Pops anything that was pushed by PROLOGUE, and returns.
-
-; REP_RET:
-; Use this instead of RET if it's a branch target.
-
-; registers:
-; rN and rNq are the native-size register holding function argument N
-; rNd, rNw, rNb are dword, word, and byte size
-; rNh is the high 8 bits of the word size
-; rNm is the original location of arg N (a register or on the stack), dword
-; rNmp is native size
