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.

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.

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.

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,
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
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
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.
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
- 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
- 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
- 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
vpxenc: add quantizer histogram display
vpxenc: add rate histogram display
update configure for ios sdk 4.3
Avoid text relocations in ARM vp8 decoder
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
Reworked loopfilter to precalculate more parameters
SSE2/SSSE3 optimizations for build_predictors_mbuv{,_s}().

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
of older releases should refer to the Upgrading notes in this
document for that release.

- Quality:
Best quality mode improved PSNR 6.3%, and SSIM 6.1%. This release
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.
* 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
* 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
$ 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

README - 23 March 2015
Welcome to the WebM VP8/VP9 Codec SDK!
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.
* All Windows builds require that Cygwin[2] be installed.
* Building the documentation requires Doxygen[3]. If you do not
have this package, the install-docs option will be disabled.
* Downloading the data for the unit tests requires curl[4] 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[5]. These requirements are optional if not running the unit
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. 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:
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.
5. 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.
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
This library is an open source project supported by its community. Please
please email for help.

# This file is to be used for compiling libvpx for Android using the NDK.
# In an Android project place a libvpx checkout in the jni directory.
# Run the configure script from the jni directory. Base libvpx
# encoder/decoder configuration will look similar to:
# ./libvpx/configure --target=armv7-android-gcc --disable-examples \
# --sdk-path=/opt/android-ndk-r6b/
# When targeting Android, realtime-only is enabled by default. This can
# be overridden by adding the command line flag:
# --disable-realtime-only
# This will create .mk files that contain variables that contain the
# source files to compile.
# Place an file in the jni directory that references the
# file in the libvpx directory:
# LOCAL_PATH := $(call my-dir)
# include $(CLEAR_VARS)
# include jni/libvpx/build/make/
# There are currently two TARGET_ARCH_ABI targets for ARM.
# armeabi and armeabi-v7a. armeabi-v7a is selected by creating an
# in the jni directory that contains:
# APP_ABI := armeabi-v7a
# By default libvpx will detect at runtime the existance of NEON extension.
# For this we import the 'cpufeatures' module from the NDK sources.
# libvpx can also be configured without this runtime detection method.
# Configuring with --disable-runtime-cpu-detect will assume presence of NEON.
# Configuring with --disable-runtime-cpu-detect --disable-neon \
# --disable-neon-asm
# will remove any NEON dependency.
# To change to building armeabi, run ./libvpx/configure again, but with
# --target=armv6-android-gcc and modify the file to
# set APP_ABI := armeabi
# Running ndk-build will build libvpx and include it in your project.
# Use the makefiles generated by upstream configure to determine which files to
# build. Also set any architecture-specific flags.
