2019-07-15 v1.8.1 "Orpington Duck"
This release collects incremental improvements to many aspects of the library.
- Upgrading:
VP8E_SET_CPUUSED now accepts values up to 9 for vp9.
VPX_CTRL_VP9E_SET_MAX_INTER_BITRATE_PCT had a spelling fix (was VP8E).

for practically every use case.
- Bug fixes:
vp9-rtc: Fix color artifacts for speed >= 8.
2019-01-31 v1.8.0 "Northern Shoveler Duck"
This release focused on encoding performance for realtime and VOD use cases.
- Upgrading:
This adds and improves several vp9 controls. Most are related to SVC:
VP9E_SET_SVC_FRAME_DROP_LAYER:
- Frame dropping in SVC.
VP9E_SET_SVC_INTER_LAYER_PRED:
- Inter-layer prediction in SVC.
VP9E_SET_SVC_GF_TEMPORAL_REF:
- Enable long term temporal reference in SVC.
VP9E_SET_SVC_REF_FRAME_CONFIG/VP9E_GET_SVC_REF_FRAME_CONFIG:
- Extend and improve this control for better flexibility in setting SVC
pattern dynamically.
VP9E_SET_POSTENCODE_DROP:
- Allow for post-encode frame dropping (applies to non-SVC too).
VP9E_SET_SVC_SPATIAL_LAYER_SYNC:
- Enable spatial layer sync frames.
VP9E_SET_SVC_LAYER_ID:
- Extend api to specify temporal id for each spatial layers.
VP9E_SET_ROI_MAP:
- Extend Region of Interest functionality to VP9.
- Enhancements:
2 pass vp9 encoding has improved substantially. When using --auto-alt-ref=6,
we see approximately 8% for VBR and 10% for CQ. When using --auto-alt-ref=1,
the gains are approximately 4% for VBR and 5% for CQ.
For real-time encoding, speed 7 has improved by ~5-10%. Encodes targeted at
screen sharing have improved when the content changes significantly (slide
sharing) or scrolls. There is a new speed 9 setting for mobile devices which
is about 10-20% faster than speed 8.
- Bug fixes:
VP9 denoiser issue.
VP9 partition issue for 1080p.
VP9 rate control improvments.
Postprocessing Multi Frame Quality Enhancement (MFQE) issue.
VP8 multithread decoder issues.
A variety of fuzzing issues.
2018-01-04 v1.7.0 "Mandarin Duck"
This release focused on high bit depth performance (10/12 bit) and vp9
encoding improvements.
- Upgrading:
This release is ABI incompatible due to new vp9 encoder features.
Frame parallel decoding for vp9 has been removed.
- Enhancements:
vp9 encoding supports additional threads with --row-mt. This can be greater
than the number of tiles.
Two new vp9 encoder options have been added:
--corpus-complexity
--tune-content=film
Additional tooling for respecting the vp9 "level" profiles has been added.
- Bug fixes:
A variety of fuzzing issues.
vp8 threading fix for ARM.

decoding processes.
- Upgrading:
This release is ABI compatible with 1.6.0.
- Enhancements:
Faster VP9 encoding and decoding.
High bit depth builds now provide similar speed for 8 bit encode and decode
for x86 targets. Other platforms and higher bit depth improvements are in
progress.
- Bug Fixes:
A variety of fuzzing issues.
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.
2015-11-09 v1.5.0 "Javan Whistling Duck"
This release improves upon the VP9 encoder and speeds up the encoding and
decoding processes.
- Upgrading:
This release is ABI incompatible with 1.4.0. It drops deprecated VP8
controls and adds a variety of VP9 controls for testing.
The vpxenc utility now prefers VP9 by default.
- Enhancements:
Faster VP9 encoding and decoding
Smaller library size by combining functions used by VP8 and VP9
- 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
YUV 4:2:2 and 4:4:4 support in VP9
10 and 12bit support in VP9

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:
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.

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.

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.

- 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.

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
called "CQ," which changes the allocation of bits within a clip to

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.

README - 15 July 2019
Welcome to the WebM VP8/VP9 Codec SDK!
COMPILING THE APPLICATIONS/LIBRARIES:
The build system used is similar to autotools. Building generally consists of
"configuring" with your desired build options, then using GNU make to build
the application.
1. Prerequisites
* All x86 targets require the Yasm[1] assembler be installed[2].
* All Windows builds require that Cygwin[3] be installed.
* Building the documentation requires Doxygen[4]. If you do not
have this package, the install-docs option will be disabled.
* Downloading the data for the unit tests requires curl[5] and sha1sum.
sha1sum is provided via the GNU coreutils, installed by default on
many *nix platforms, as well as MinGW and Cygwin. If coreutils is not
available, a compatible version of sha1sum can be built from
source[6]. These requirements are optional if not running the unit
tests.
[1]: http://www.tortall.net/projects/yasm
[2]: For Visual Studio the base yasm binary (not vsyasm) should be in the
PATH for Visual Studio. For VS2017 it is sufficient to rename
yasm-<version>-<arch>.exe to yasm.exe and place it in:
Program Files (x86)/Microsoft Visual Studio/2017/<level>/Common7/Tools/
[3]: http://www.cygwin.com
[4]: http://www.doxygen.org
[5]: http://curl.haxx.se
[6]: http://www.microbrew.org/tools/md5sha1sum/
2. Out-of-tree builds
Out of tree builds are a supported method of building the application. For
an out of tree build, the source tree is kept separate from the object
files produced during compilation. For instance:
$ mkdir build
$ cd build
$ ../libvpx/configure <options>
$ make
3. Configuration options
The 'configure' script supports a number of options. The --help option can be
used to get a list of supported options:
$ ../libvpx/configure --help
4. Compiler analyzers
Compilers have added sanitizers which instrument binaries with information
about address calculation, memory usage, threading, undefined behavior, and
other common errors. To simplify building libvpx with some of these features
use tools/set_analyzer_env.sh before running configure. It will set the
compiler and necessary flags for building as well as environment variables
read by the analyzer when testing the binaries.
$ source ../libvpx/tools/set_analyzer_env.sh address
5. Cross development
For cross development, the most notable option is the --target option. The
most up-to-date list of supported targets can be found at the bottom of the
--help output of the configure script. As of this writing, the list of
available targets is:
arm64-android-gcc

generic-gnu
The generic-gnu target, in conjunction with the CROSS environment variable,
can be used to cross compile architectures that aren't explicitly listed, if
the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains
will likely work as well. For instance, to build using the mipsel-linux-uclibc
toolchain, the following command could be used (note, POSIX SH syntax, adapt
to your shell as necessary):
$ CROSS=mipsel-linux-uclibc- ../libvpx/configure
In addition, the executables to be invoked can be overridden by specifying the
environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be
passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.
6. Configuration errors
If the configuration step fails, the first step is to look in the error log.
This defaults to config.log. This should give a good indication of what went
wrong. If not, contact us for support.
VP8/VP9 TEST VECTORS:
The test vectors can be downloaded and verified using the build system after
running configure. To specify an alternate directory the
LIBVPX_TEST_DATA_PATH environment variable can be used.
$ ./configure --enable-unit-tests
$ LIBVPX_TEST_DATA_PATH=../libvpx-test-data make testdata
CODE STYLE:
The coding style used by this project is enforced with clang-format using the
configuration contained in the .clang-format file in the root of the
repository.
Before pushing changes for review you can format your code with:
# Apply clang-format to modified .c, .h and .cc files
$ clang-format -i --style=file \
$(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
Check the .clang-format file for the version used to generate it if there is
any difference between your local formatting and the review system.

## configure
##
## This script is the front-end to the build system. It provides a similar
## interface to standard configure scripts with some extra bits for dealing
## with toolchains that differ from the standard POSIX interface and
## for extracting subsets of the source tree. In theory, reusable parts
## of this script were intended to live in build/make/configure.sh,
## but in practice, the line is pretty blurry.
##
## This build system is based in part on the FFmpeg configure script.

//
// MD5 algorithm
// -------------
// The Message-Digest 5 (MD5) is a well known hash function. We have provided
// an implementation derived from the RSA Data Security, Inc. MD5 Message-Digest
// Algorithm for your use. Our implmentation only changes the interface of this

// Processing The Decoded Data
// ---------------------------

// is processed, then U, then V. It is important to honor the image's `stride`

// Decode With Drops Example
// =========================
//
// This is an example utility which drops a series of frames, as specified
// on the command line. This is useful for observing the error recovery
// features of the codec.
//
// Usage
// -----
// This example adds a single argument to the `simple_decoder` example,
// which specifies the range or pattern of frames to drop. The parameter is
// parsed as follows:
//
// Dropping A Range Of Frames
// --------------------------
// To drop a range of frames, specify the starting frame and the ending
// frame to drop, separated by a dash. The following command will drop
// frames 5 through 10 (base 1).
//
// $ ./decode_with_drops in.ivf out.i420 5-10
//
//
// Dropping A Pattern Of Frames
// ----------------------------
// To drop a pattern of frames, specify the number of frames to drop and
// the number of frames after which to repeat the pattern, separated by
// a forward-slash. The following command will drop 3 of 7 frames.
// Specifically, it will decode 4 frames, then drop 3 frames, and then
// repeat.
//
// $ ./decode_with_drops in.ivf out.i420 3/7
//
//
// Extra Variables
// ---------------
// This example maintains the pattern passed on the command line in the
// `n`, `m`, and `is_range` variables:
//
//
// Making The Drop Decision
// ------------------------
// The example decides whether to drop the frame based on the current
// frame number, immediately before decoding the frame.

// initialization time. This is done by passing the VPX_CODEC_USE_POSTPROC
// flag to `vpx_codec_dec_init`. If the codec does not support
// postprocessing, this call will return VPX_CODEC_INCAPABLE. For
// demonstration purposes, we also fall back to default initialization if
// the codec does not provide support.
//
// Using Adaptive Postprocessing
// -----------------------------
// VP6 provides "adaptive postprocessing." It will automatically select the
// best postprocessing filter on a frame by frame basis based on the amount
// of time remaining before the user's specified deadline expires. The
// special value 0 indicates that the codec should take as long as
// necessary to provide the best quality frame. This example gives the
// codec 15ms (15000us) to return a frame. Remember that this is a soft
// deadline, and the codec may exceed it doing its regular processing. In
// these cases, no additional postprocessing will be done.
//
// Codec Specific Postprocessing Controls
// --------------------------------------
// Some codecs provide fine grained controls over their built-in
// postprocessors. VP8 is one example. The following sample code toggles
// postprocessing on and off every 15 frames.

// VP8 Set Active and ROI Maps
// ===========================
//
// This is an example demonstrating how to control the VP8 encoder's
// ROI and Active maps.
//
// ROI (Reigon of Interest) maps are a way for the application to assign
// each macroblock in the image to a region, and then set quantizer and
// filtering parameters on that image.
//
// Active maps are a way for the application to specify on a
// macroblock-by-macroblock basis whether there is any activity in that
// macroblock.
//
//
// Configuration
// -------------
// An ROI map is set on frame 22. If the width of the image in macroblocks
// is evenly divisble by 4, then the output will appear to have distinct
// columns, where the quantizer, loopfilter, and static threshold differ
// from column to column.
//
// An active map is set on frame 33. If the width of the image in macroblocks
// is evenly divisble by 4, then the output will appear to have distinct
// columns, where one column will have motion and the next will not.
//
// The active map is cleared on frame 44.
//
// Observing The Effects
// ---------------------
// Use the `simple_decoder` example to decode this sample, and observe
// the change in the image at frames 22, 33, and 44.

// Simple Decoder
// ==============
//
// This is an example of a simple decoder loop. It takes an input file
// containing the compressed data (in IVF format), passes it through the
// decoder, and writes the decompressed frames to disk. Other decoder
// examples build upon this one.
//
// The details of the IVF format have been elided from this example for
// simplicity of presentation, as IVF files will not generally be used by
// your application. In general, an IVF file consists of a file header,
// followed by a variable number of frames. Each frame consists of a frame
// header followed by a variable length payload. The length of the payload
// is specified in the first four bytes of the frame header. The payload is
// the raw compressed data.
//
// Standard Includes
// -----------------
// For decoders, you only have to include `vpx_decoder.h` and then any
// header files for the specific codecs you use. In this case, we're using
// vp8.
//
// Initializing The Codec
// ----------------------
// The libvpx decoder is initialized by the call to vpx_codec_dec_init().
// Determining the codec interface to use is handled by VpxVideoReader and the
// functions prefixed with vpx_video_reader_. Discussion of those functions is
// beyond the scope of this example, but the main gist is to open the input file
// and parse just enough of it to determine if it's a VPx file and which VPx
// codec is contained within the file.
// Note the NULL pointer passed to vpx_codec_dec_init(). We do that in this
// example because we want the algorithm to determine the stream configuration
// (width/height) and allocate memory automatically.
//
// Decoding A Frame
// ----------------
// Once the frame has been read into memory, it is decoded using the
// `vpx_codec_decode` function. The call takes a pointer to the data
// (`frame`) and the length of the data (`frame_size`). No application data
// is associated with the frame in this example, so the `user_priv`
// parameter is NULL. The `deadline` parameter is left at zero for this
// example. This parameter is generally only used when doing adaptive post
// processing.
//
// Codecs may produce a variable number of output frames for every call to
// `vpx_codec_decode`. These frames are retrieved by the
// `vpx_codec_get_frame` iterator function. The iterator variable `iter` is
// initialized to NULL each time `vpx_codec_decode` is called.
// `vpx_codec_get_frame` is called in a loop, returning a pointer to a
// decoded image or NULL to indicate the end of list.
//
// Processing The Decoded Data
// ---------------------------
// In this example, we simply write the encoded data to disk. It is
// important to honor the image's `stride` values.
//
// Cleanup
// -------
// The `vpx_codec_destroy` call frees any memory allocated by the codec.
//
// Error Handling
// --------------
// This example does not special case any error return codes. If there was
// an error, a descriptive message is printed and the program exits. With
// few exceptions, vpx_codec functions return an enumerated error status,
// with the value `0` indicating success.

// Simple Encoder
// ==============
//
// This is an example of a simple encoder loop. It takes an input file in
// YV12 format, passes it through the encoder, and writes the compressed
// frames to disk in IVF format. Other decoder examples build upon this
// one.
//
// The details of the IVF format have been elided from this example for
// simplicity of presentation, as IVF files will not generally be used by
// your application. In general, an IVF file consists of a file header,
// followed by a variable number of frames. Each frame consists of a frame
// header followed by a variable length payload. The length of the payload
// is specified in the first four bytes of the frame header. The payload is
// the raw compressed data.
//
// Standard Includes
// -----------------
// For encoders, you only have to include `vpx_encoder.h` and then any
// header files for the specific codecs you use. In this case, we're using
// vp8.
//
// Getting The Default Configuration
// ---------------------------------
// Encoders have the notion of "usage profiles." For example, an encoder
// may want to publish default configurations for both a video
// conferencing application and a best quality offline encoder. These
// obviously have very different default settings. Consult the
// documentation for your codec to see if it provides any default
// configurations. All codecs provide a default configuration, number 0,
// which is valid for material in the vacinity of QCIF/QVGA.
//
// Updating The Configuration
// ---------------------------------
// Almost all applications will want to update the default configuration
// with settings specific to their usage. Here we set the width and height
// of the video file to that specified on the command line. We also scale
// the default bitrate based on the ratio between the default resolution
// and the resolution specified on the command line.
//
// Initializing The Codec
// ----------------------
// The encoder is initialized by the following code.
//
// Encoding A Frame
// ----------------
// The frame is read as a continuous block (size width * height * 3 / 2)
// from the input file. If a frame was read (the input file has not hit
// EOF) then the frame is passed to the encoder. Otherwise, a NULL
// is passed, indicating the End-Of-Stream condition to the encoder. The
// `frame_cnt` is reused as the presentation time stamp (PTS) and each
// frame is shown for one frame-time in duration. The flags parameter is
// unused in this example. The deadline is set to VPX_DL_REALTIME to
// make the example run as quickly as possible.
// Forced Keyframes
// ----------------
// Keyframes can be forced by setting the VPX_EFLAG_FORCE_KF bit of the
// flags passed to `vpx_codec_control()`. In this example, we force a
// keyframe every <keyframe-interval> frames. Note, the output stream can
// contain additional keyframes beyond those that have been forced using the
// VPX_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
// encoder.
//
// Processing The Encoded Data
// ---------------------------
// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data
// for this frame. We write a IVF frame header, followed by the raw data.
//
// Cleanup
// -------
// The `vpx_codec_destroy` call frees any memory allocated by the codec.
//
// Error Handling
// --------------
// This example does not special case any error return codes. If there was
// an error, a descriptive message is printed and the program exits. With
// few exeptions, vpx_codec functions return an enumerated error status,

// versus one encoded with the `simple_encoder` example.

// Two Pass Encoder
// ================
//
// This is an example of a two pass encoder loop. It takes an input file in
// YV12 format, passes it through the encoder twice, and writes the compressed
// frames to disk in IVF format. It builds upon the simple_encoder example.
//
// Twopass Variables
// -----------------
// Twopass mode needs to track the current pass number and the buffer of
// statistics packets.
//
// Updating The Configuration
// ---------------------------------
// In two pass mode, the configuration has to be updated on each pass. The
// statistics buffer is passed on the last pass.
//
// Encoding A Frame
// ----------------
// Encoding a frame in two pass mode is identical to the simple encoder
// example. To increase the quality while sacrificing encoding speed,
// VPX_DL_BEST_QUALITY can be used in place of VPX_DL_GOOD_QUALITY.
//
// Processing Statistics Packets
// -----------------------------
// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data
// for this frame. We write a IVF frame header, followed by the raw data.
//
//
// Pass Progress Reporting
// -----------------------------
// It's sometimes helpful to see when each pass completes.
//
//
// Clean-up
// -----------------------------
// Destruction of the encoder instance must be done on each pass. The
// raw image should be destroyed at the end as usual.

// VP8 Set Reference Frame
// =======================
//
// This is an example demonstrating how to overwrite the VP8 encoder's
// internal reference frame. In the sample we set the last frame to the
// current frame. If this is done at a cut scene it will avoid a keyframe.
// This technique could be used to bounce between two cameras.
//
// Note that the decoder would also have to set the reference frame to the
// same value on the same frame, or the video will become corrupt.
//
// Usage
// -----
// This example adds a single argument to the `simple_encoder` example,
// which specifies the frame number to update the reference frame on.
// The parameter is parsed as follows:
//
//
// Extra Variables
// ---------------
// This example maintains the frame number passed on the command line
// in the `update_frame_num` variable.
//
//
// Configuration
// -------------
//
// The reference frame is updated on the frame specified on the command
// line.
//
// Observing The Effects
// ---------------------
// Use the `simple_encoder` example to encode a sample with a cut scene.
// Determine the frame number of the cut scene by looking for a generated
// key-frame (indicated by a 'K'). Supply that frame number as an argument
// to this example, and observe that no key-frame is generated.

// VP9 Set Reference Frame
// ============================
//
// This is an example demonstrating how to overwrite the VP9 encoder's
// internal reference frame. In the sample we set the last frame to the
// current frame. This technique could be used to bounce between two cameras.
//
// The decoder would also have to set the reference frame to the same value
// on the same frame, or the video will become corrupt. The 'test_decode'
// variable is set to 1 in this example that tests if the encoder and decoder
// results are matching.
//
// Usage
// -----
// This example encodes a raw video. And the last argument passed in specifies
// the frame number to update the reference frame on. For example, run
// examples/vp9cx_set_ref 352 288 in.yuv out.ivf 4 30
// The parameter is parsed as follows:
//
//
// Extra Variables
// ---------------
// This example maintains the frame number passed on the command line
// in the `update_frame_num` variable.
//
//
// Configuration
// -------------
//
// The reference frame is updated on the frame specified on the command
// line.
//
// Observing The Effects
// ---------------------
// The encoder and decoder results should be matching when the same reference
// frame setting operation is done in both encoder and decoder. Otherwise,
// the encoder/decoder mismatch would be seen.

This word, or the terms "REQUIRED" or "SHALL", mean that the
definition is an absolute requirement of the specification.
\section MUSTNOT MUST NOT
\anchor SHALLNOT
This phrase, or the phrase "SHALL NOT", mean that the
definition is an absolute prohibition of the specification.
\section SHOULD
\anchor RECOMMENDED
This word, or the adjective "RECOMMENDED", mean that there
may exist valid reasons in particular circumstances to ignore a
particular item, but the full implications must be understood and
carefully weighed before choosing a different course.
\section SHOULDNOT SHOULD NOT
\anchor NOTRECOMMENDED
This phrase, or the phrase "NOT RECOMMENDED" mean that
there may exist valid reasons in particular circumstances when the
particular behavior is acceptable or even useful, but the full
implications should be understood and the case carefully weighed
before implementing any behavior described with this label.
\section MAY
\anchor OPTIONAL
This word, or the adjective "OPTIONAL", mean that an item is
truly optional. One vendor may choose to include the item because a
particular marketplace requires it or because the vendor feels that
it enhances the product while another vendor may omit the same item.
An implementation which does not include a particular option \ref MUST be
prepared to interoperate with another implementation which does
include the option, though perhaps with reduced functionality. In the
same vein an implementation which does include a particular option
\ref MUST be prepared to interoperate with another implementation which
does not include the option (except, of course, for the feature the
option provides.)

Android.mk will build vpx unittests on android.
1) Configure libvpx from the parent directory:
./libvpx/configure --target=armv7-android-gcc --enable-external-build \
--enable-postproc --disable-install-srcs --enable-multi-res-encoding \
--enable-temporal-denoising --disable-unit-tests --disable-install-docs \
--disable-examples --disable-runtime-cpu-detect
2) From the parent directory, invoke ndk-build:
NDK_PROJECT_PATH=. ndk-build APP_BUILD_SCRIPT=./libvpx/test/android/Android.mk \
APP_ABI=armeabi-v7a APP_PLATFORM=android-18 APP_OPTIM=release \
APP_STL=c++_static
Note: Both adb and ndk-build are available at:
https://developer.android.com/studio#downloads
https://developer.android.com/ndk/downloads
3) Run get_files.py to download the test files:
python get_files.py -i /path/to/test-data.sha1 -o /path/to/put/files \
-u http://downloads.webmproject.org/test_data/libvpx
4) Transfer files to device using adb. Ensure you have proper permissions for
the target
adb push /path/to/test_files /data/local/tmp
adb push /path/to/built_libs /data/local/tmp
NOTE: Built_libs defaults to parent_dir/libs/armeabi-v7a
5) Run tests:
adb shell
(on device)
cd /data/local/tmp
LD_LIBRARY_PATH=. ./vpx_test
