March 16th, 2026, FFmpeg 8.1 "Hoare"
A new minor release, FFmpeg 8.1 "Hoare", is now available for
download. Here are some of the highlights:
* Decoders: xHE-AAC Mps212 (experimental) MPEG-H decoding via
libmpeghdec
* EXIF Metadata Parsing
* LCEVC: support for parsing and forwarding metadata
* Vulkan compute-based codecs: ProRes encoding and decoding, DPX
decoding
* D3D12: D3D12 H.264/AV1 encoding, scale_d3d12, mestimate_d3d12,
deinterlace_d3d12 filters
* Rockchip H.264/HEVC hardware encoding
* IAMF: Projection mode Ambisonic Audio Elements muxing and
demuxing
* Formats: hxvs demuxer
* Filters: drawvg, vpp_amf
This release features a lot of internal changes and bugfixes. The
groundwork for the upcoming swscale rewrite is progressing. The
Vulkan compute-based codecs, and a few filters, no longer depend on
runtime GLSL compilation, which speeds up their initialization.
A companion post about the Vulkan Compute-based codec implementations
has been published on the Khronos blog, featuring technical details
on the implementations and future plans.
We recommend users, distributors, and system integrators to upgrade
unless they use current git master.
August 22nd, 2025, FFmpeg 8.0 "Huffman"
A new major release, FFmpeg 8.0 "Huffman", is now available for
download. Thanks to several delays, and modernization of our entire
infrastructure, this release ended up being one of our largest
releases to date. In short, its new features are:
* Native decoders: APV, ProRes RAW, RealVideo 6.0, Sanyo LD-ADPCM,
G.728
* VVC decoder improvements: IBC, ACT, Palette Mode
* Vulkan compute-based codecs: FFv1 (encode and decode), ProRes RAW
(decode only)
* Hardware accelerated decoding: Vulkan VP9, VAAPI VVC, OpenHarmony
H264/5
* Hardware accelerated encoding: Vulkan AV1, OpenHarmony H264/5
* Formats: MCC, G.728, Whip, APV
* Filters: colordetect, pad_cuda, scale_d3d11, Whisper, and others
A new class of decoders and encoders based on pure Vulkan compute
implementation have been added. Vulkan is a cross-platform, open
standard set of APIs that allows programs to use GPU hardware in
various ways, from drawing on screen, to doing calculations, to
decoding video via custom hardware accelerators. Rather than using a
custom hardware accelerator present, these codecs are based on
compute shaders, and work on any implementation of Vulkan 1.3.
Decoders use the same hwaccel API and commands, so users do not need
to do anything special to enable them, as enabling Vulkan decoding is
sufficient to use them.
Encoders, like our hardware accelerated encoders, require specifying
a new encoder (ffv1_vulkan). Currently, the only codecs supported
are: FFv1 (encoding and decoding) and ProRes RAW (decode only).
ProRes (encode+decode) and VC-2 (encode+decode) implementations are
complete and currently in review, to be merged soon and available
with the next minor release.
Only codecs specifically designed for parallelized decoding can be
implemented in such a way, with more mainstream codecs not being
planned for support.
Depending on the hardware, these new codecs can provide very
significant speedups, and open up possibilities to work with them for
situations like non-linear video editors and lossless screen
recording/streaming, so we are excited to learn what our downstream
users can make with them.
The project has recently started to modernize its infrastructure. Our
mailing list servers have been fully upgraded, and we have recently
started to accept contributions via a new forge, available on
code.ffmpeg.org, running a Forgejo instance.
As usual, we recommend that users, distributors, and system
integrators to upgrade unless they use current git master.
September 30th, 2024, FFmpeg 7.1 "Peter"
FFmpeg 7.1 "Peter", a new major release, is now available! A full
list of changes can be found in the release changelog.
The more important highlights of the release are that the VVC
decoder, merged as experimental in version 7.0, has had enough time
to mature and be optimized enough to be declared as stable. The codec
is starting to gain traction with broadcast standardization bodies.
Support has been added for a native AAC USAC (part of the xHE-AAC
coding system) decoder, with the format starting to be adopted by
streaming websites, due to its extensive volume normalization
metadata.
MV-HEVC decoding is now supported. This is a stereoscopic coding tool
that begun to be shipped and generated by recent phones and VR
headsets.
LC-EVC decoding, an enhancement metadata layer to attempt to improve
the quality of codecs, is now supported via an external library.
Support for Vulkan encoding, with H264 and HEVC was merged. This
finally allows fully Vulkan-based decode-filter-encode pipelines, by
having a sink for Vulkan frames, other than downloading or displaying
them. The encoders have feature-parity with their VAAPI
implementation counterparts. Khronos has announced that support for
AV1 encoding is also coming soon to Vulkan, and FFmpeg is aiming to
have day-one support.
In addition to the above, this release has had a lot of important
internal work done. By far, the standout internally are the
improvements made for full-range images. Previously, color range data
had two paths, no negotiation, and was unreliably forwarded to
filters, encoders, muxers. Work on cleaning the system up started
more than 10 years ago, however this stalled due to how fragile the
system was, and that breaking behaviour would be unacceptable. The
new system fixes this, so now color range is forwarded correctly and
consistently everywhere needed, and also laid the path for more
advanced forms of negotiation.
Cropping metadata is now supported with Matroska and MP4 formats.
This metadata is important not only for archival, but also with AV1,
as hardware encoders require its signalling due to the codec not
natively supporting one.
As usual, we recommend that users, distributors, and system
integrators to upgrade unless they use current git master.
September 11th, 2024, Coverity
The number of issues FFmpeg has in Coverity (a static analyzer) is
now lower than it has been since 2016. Our defect density is less
than one 30th of the average in OSS with over a million code lines.
All this was possible thanks to a grant from the Sovereign Tech Fund.
Coverity Lifetime Graph till 2024-08
June 2nd, 2024, native xHE-AAC decoder
FFmpeg now implements a native xHE-AAC decoder. Currently, streams
without (e)SBR, USAC or MPEG-H Surround are supported, which means
the majority of xHE-AAC streams in use should work. Support for USAC
and (e)SBR is coming soon. Work is also ongoing to improve its
stability and compatibility. During the process we found several
specification issues, which were then submitted back to the authors
for discussion and potential inclusion in a future errata.
May 13th, 2024, Sovereign Tech Fund
The FFmpeg community is excited to announce that Germany's Sovereign
Tech Fund has become its first governmental sponsor. Their support
will help sustain the maintainance of the FFmpeg project, a critical
open-source software multimedia component essential to bringing audio
and video to billions around the world everyday.
April 5th, 2024, FFmpeg 7.0 "Dijkstra"
A new major release, FFmpeg 7.0 "Dijkstra", is now available for
download. The most noteworthy changes for most users are a native VVC
decoder (currently experimental, until more fuzzing is done), IAMF
support, or a multi-threaded ffmpeg CLI tool.
This release is not backwards compatible, removing APIs deprecated
before 6.0. The biggest change for most library callers will be the
removal of the old bitmask-based channel layout API, replaced by the
AVChannelLayout API allowing such features as custom channel
ordering, or Ambisonics. Certain deprecated ffmpeg CLI options were
also removed, and a C11-compliant compiler is now required to build
the code.
As usual, there is also a number of new supported formats and codecs,
new filters, APIs, and countless smaller features and bugfixes.
Compared to 6.1, the git repository contains almost ~2000 new commits
by ~100 authors, touching >100000 lines in ~2000 files -- thanks to
everyone who contributed. See the Changelog, APIchanges, and the git
log for more comprehensive lists of changes.
January 3rd, 2024, native VVC decoder
The libavcodec library now contains a native VVC (Versatile Video
Coding) decoder, supporting a large subset of the codec's features.
Further optimizations and support for more features are coming soon.
The code was written by Nuo Mi, Xu Mu, Frank Plowman, Shaun Loo, and
Wu Jianhua.
December 18th, 2023, IAMF support
The libavformat library can now read and write IAMF (Immersive Audio)
files. The ffmpeg CLI tool can configure IAMF structure with the new
-stream_group option. IAMF support was written by James Almer.
December 12th, 2023, multi-threaded ffmpeg CLI tool
Thanks to a major refactoring of the ffmpeg command-line tool, all
the major components of the transcoding pipeline (demuxers, decoders,
filters, encodes, muxers) now run in parallel. This should improve
throughput and CPU utilization, decrease latency, and open the way to
other exciting new features.
Note that you should not expect significant performance improvements
in cases where almost all computational time is spent in a single
component (typically video encoding).
November 10th, 2023, FFmpeg 6.1 "Heaviside"
FFmpeg 6.1 "Heaviside", a new major release, is now available! Some

variable-fields elements within the same parent element
* ffprobe -output_format option added as an alias of -of
This release had been overdue for at least half a year, but due to
constant activity in the repository, had to be delayed, and we were
finally able to branch off the release recently, before some of the
large changes scheduled for 7.0 were merged.
Internally, we have had a number of changes too. The FFT, MDCT, DCT
and DST implementation used for codecs and filters has been fully
replaced with the faster libavutil/tx (full article about it coming
soon).
This also led to a reduction in the the size of the compiled binary,
which can be noticeable in small builds.
There was a very large reduction in the total amount of allocations
being done on each frame throughout video decoders, reducing
overhead.
RISC-V optimizations for many parts of our DSP code have been merged,
with mainly the large decoders being left.
There was an effort to improve the correctness of timestamps and
frame durations of each packet, increasing the accurracy of variable
frame rate video.
Next major release will be version 7.0, scheduled to be released in
February. We will attempt to better stick to the new release schedule
we announced at the start of this year.
We strongly recommend users, distributors, and system integrators to
upgrade unless they use current git master.
May 31st, 2023, Vulkan decoding
A few days ago, Vulkan-powered decoding hardware acceleration code
was merged into the codebase. This is the first vendor-generic and
platform-generic decode acceleration API, enabling the same code to
be used on multiple platforms, with very minimal overhead. This is
also the first multi-threaded hardware decoding API, and our code
makes full use of this, saturating all available decode engines the
hardware exposes.
Those wishing to test the code can read our documentation page. For
those who would like to integrate FFmpeg's Vulkan code to demux,
parse, decode, and receive a VkImage to present or manipulate,
documentation and examples are available in our source tree.
Currently, using the latest available git checkout of our repository
is required. The functionality will be included in stable branches
with the release of version 6.1, due to be released soon.
As this is also the first practical implementation of the
specifications, bugs may be present, particularly in drivers, and,
although passing verification, the implementation itself. New codecs,
and encoding support are also being worked on, by both the Khronos
organization for standardizing, and us as implementing it, and giving
feedback on improving.
February 28th, 2023, FFmpeg 6.0 "Von Neumann"
A new major release, FFmpeg 6.0 "Von Neumann", is now available for
download. This release has many new encoders and decoders, filters,
ffmpeg CLI tool improvements, and also, changes the way releases are
done. All major releases will now bump the version of the ABI. We
plan to have a new major release each year. Another release-specific
change is that deprecated APIs will be removed after 3 releases, upon
the next major bump. This means that releases will be done more often
and will be more organized.
New decoders featured are Bonk, RKA, Radiance, SC-4, APAC, VQC,
WavArc and a few ADPCM formats. QSV and NVenc now support AV1
encoding. The FFmpeg CLI (we usually reffer to it as ffmpeg.c to
avoid confusion) has speed-up improvements due to threading, as well
as statistics options, and the ability to pass option values for
filters from a file. There are quite a few new audio and video
filters, such as adrc, showcwt, backgroundkey and ssim360, with a few
hardware ones too. Finally, the release features many
behind-the-scenes changes, including a new FFT and MDCT
implementation used in codecs (expect a blog post about this soon),
numerous bugfixes, better ICC profile handling and colorspace
signalling improvement, introduction of a number of RISC-V vector and
scalar assembly optimized routines, and a few new improved APIs,
which can be viewed in the doc/APIchanges file in our tree. A few
submitted features, such as the Vulkan improvements and more FFT
optimizations will be in the next minor release, 6.1, which we plan
to release soon, in line with our new release schedule. Some
highlights are:
* Radiance HDR image support
* ddagrab (Desktop Duplication) video capture filter

October 5th, 2019, Bright Lights
FFmpeg has added a realtime bright flash removal filter to
libavfilter.
Note that this filter is not FDA approved, nor are we medical
professionals. Nor has this filter been tested with anyone who has
photosensitive epilepsy. FFmpeg and its photosensitivity filter are
not making any medical claims.
That said, this is a new video filter that may help photosensitive
people watch tv, play video games or even be used with a VR headset
to block out epiletic triggers such as filtered sunlight when they
are outside. Or you could use it against those annoying white flashes
on your tv screen. The filter fails on some input, such as the
Incredibles 2 Screen Slaver scene. It is not perfect. If you have
other clips that you want this filter to work better on, please
report them to us on our trac.
See for yourself. Example was made with -vf photosensitivity=20:0.8
We are not professionals. Please use this in your medical studies to
advance epilepsy research. If you decide to use this in a medical
setting, or make a hardware hdmi input output realtime tv filter, or
find another use for this, please let me know. This filter was a
feature request of mine since 2013.

October 30th, 2016, Results: Summer Of Code 2016.
This has been a long time coming but we wanted to give a proper
closure to our participation in this run of the program and it takes
time. Sometimes it's just to get the final report for each project
trimmed down, others, is finalizing whatever was still in progress
when the program finished: final patches need to be merged, TODO
lists stabilized, future plans agreed; you name it.
Without further ado, here's the silver-lining for each one of the
projects we sought to complete during this Summer of Code season:
FFv1 (Mentor: Michael Niedermayer)
Stanislav Dolganov designed and implemented experimental support for
motion estimation and compensation in the lossless FFV1 codec. The
design and implementation is based on the snow video codec, which
uses OBMC. Stanislav's work proved that significant compression gains
can be achieved with inter frame compression. FFmpeg welcomes
Stanislav to continue working beyond this proof of concept and bring
its advances into the official FFV1 specification within the IETF.
Self test coverage (Mentor: Michael Niedermayer)
Petru Rares Sincraian added several self-tests to FFmpeg and
successfully went through the in-some-cases tedious process of fine
tuning tests parameters to avoid known and hard to avoid problems,
like checksum mismatches due to rounding errors on the myriad of
platforms we support. His work has improved the code coverage of our
self tests considerably.
MPEG-4 ALS encoder implementation (Mentor: Thilo Borgmann)
Umair Khan updated and integrated the ALS encoder to fit in the
current FFmpeg codebase. He also implemented a missing feature for
the ALS decoder that enables floating-point sample decoding. FFmpeg
support for MPEG-4 ALS has been improved significantly by Umair's
work. We welcome him to keep maintaining his improvements and hope
for great contributions to come.
Tee muxer improvements (Mentor: Marton Balint)
Jan Sebechlebsky's generic goal was to improve the tee muxer so it
tolerated blocking IO and allowed transparent error recovery. During
the design phase it turned out that this functionality called for a
separate muxer, so Jan spent his summer working on the so-called FIFO
muxer, gradually fixing issues all over the codebase. He succeeded in
his task, and the FIFO muxer is now part of the main repository,
alongside several other improvements he made in the process.
TrueHD encoder (Mentor: Rostislav Pehlivanov)
Jai Luthra's objective was to update the out-of-tree and pretty much
abandoned MLP (Meridian Lossless Packing) encoder for libavcodec and
improve it to enable encoding to the TrueHD format. For the
qualification period the encoder was updated such that it was usable
and throughout the summer, successfully improved adding support for
multi-channel audio and TrueHD encoding. Jai's code has been merged
into the main repository now. While a few problems remain with
respect to LFE channel and 32 bit sample handling, these are in the
process of being fixed such that effort can be finally put in
improving the encoder's speed and efficiency.
Motion interpolation filter (Mentor: Paul B Mahol)
Davinder Singh investigated existing motion estimation and
interpolation approaches from the available literature and previous
work by our own: Michael Niedermayer, and implemented filters based
on this research. These filters allow motion interpolating frame rate
conversion to be applied to a video, for example, to create a slow
motion effect or change the frame rate while smoothly interpolating
the video along the motion vectors. There's still work to be done to
call these filters 'finished', which is rather hard all things
considered, but we are looking optimistically at their future.
And that's it. We are happy with the results of the program and
immensely thankful for the opportunity of working with such an
amazing set of students. We can be a tough crowd but our mentors did
an amazing job at hand holding our interns through their journey.
Thanks also to Google for this wonderful program and to everyone that
made room in their busy lives to help making GSoC2016 a success. See
you in 2017!
September 24th, 2016, SDL1 support dropped.
Support for the SDL1 library has been dropped, due to it no longer
being maintained (as of January, 2012) and it being superseded by the
SDL2 library. As a result, the SDL1 output device has also been
removed and replaced by an SDL2 implementation. Both the ffplay and
opengl output devices have been updated to support SDL2.
August 9th, 2016, FFmpeg 3.1.2 "Laplace"
FFmpeg 3.1.2, a new point release from the 3.1 release branch, is now
available! It fixes several bugs.
We recommend users, distributors, and system integrators, to upgrade
unless they use current git master.
July 10th, 2016, ffserver program being dropped
After thorough deliberation, we're announcing that we're about to
drop the ffserver program from the project starting with the next
release. ffserver has been a problematic program to maintain due to
its use of internal APIs, which complicated the recent cleanups to
the libavformat library, and block further cleanups and improvements
which are desired by API users and will be easier to maintain.
Furthermore the program has been hard for users to deploy and run due
to reliability issues, lack of knowledgable people to help and
confusing configuration file syntax. Current users and members of the
community are invited to write a replacement program to fill the same
niche that ffserver did using the new APIs and to contact us so we
may point users to test and contribute to its development.
July 1st, 2016, FFmpeg 3.1.1 "Laplace"
FFmpeg 3.1.1, a new point release from the 3.1 release branch, is now
available! It mainly deals with a few ABI issues introduced in the
previous release.
We strongly recommend users, distributors, and system integrators,
especially those who experienced issues upgrading from 3.0, to
upgrade unless they use current git master.
June 27th, 2016, FFmpeg 3.1 "Laplace"

organization. If you wish to participate as a student see our project
ideas page. You can already get in contact with mentors and start
working on qualification tasks as well as register at google and
submit your project proposal draft. Good luck!
February 15th, 2016, FFmpeg 3.0 "Einstein"
FFmpeg 3.0 "Einstein", a new major release, is now available! Some of
the highlights:
* The native FFmpeg AAC encoder has seen extensive improvements and
is no longer considered experimental

We strongly recommend users, distributors, and system integrators to
upgrade unless they use current git master.
January 30, 2016, Removing support for two external AAC encoders
We have just removed support for VisualOn AAC encoder (libvo-aacenc)
and libaacplus in FFmpeg master.
Even before marking our internal AAC encoder as stable, it was known
that libvo-aacenc was of an inferior quality compared to our native
one for most samples. However, the VisualOn encoder was used
extensively by the Android Open Source Project, and we would like to
have a tested-and-true stable option in our code base.
When first committed in 2011, libaacplus filled in the gap of
encoding High Efficiency AAC formats (HE-AAC and HE-AACv2), which was
not supported by any of the encoders in FFmpeg at that time.
The circumstances for both have changed. After the work spearheaded
by Rostislav Pehlivanov and Claudio Freire, the now-stable FFmpeg
native AAC encoder is ready to compete with much more mature
encoders. The Fraunhofer FDK AAC Codec Library for Android was added
in 2012 as the fourth supported external AAC encoder, and the one
with the best quality and the most features supported, including
HE-AAC and HE-AACv2.
Therefore, we have decided that it is time to remove libvo-aacenc and
libaacplus. If you are currently using libvo-aacenc, prepare to
transition to the native encoder (aac) when updating to the next
version of FFmpeg. In most cases it is as simple as merely swapping
the encoder name. If you are currently using libaacplus, start using
FDK AAC (libfdk_aac) with an appropriate profile option to select the
exact AAC profile that fits your needs. In both cases, you will enjoy
an audible quality improvement and as well as fewer licensing
headaches.
Enjoy!
January 16, 2016, FFmpeg 2.8.5, 2.7.5, 2.6.7, 2.5.10
We have made several new point releases (2.8.5, 2.7.5, 2.6.7, 2.5.10
). They fix various bugs, as well as CVE-2016-1897 and CVE-2016-1898.
Please see the changelog for each release for more details.
We recommend users, distributors and system integrators to upgrade
unless they use current git master.
December 5th, 2015, The native FFmpeg AAC encoder is now stable!
After seven years the native FFmpeg AAC encoder has had its
experimental flag removed and declared as ready for general use. The
encoder is transparent at 128kbps for most samples tested with
artifacts only appearing in extreme cases. Subjective quality tests
put the encoder to be of equal or greater quality than most of the
other encoders available to the public.
Licensing has always been an issue with encoding AAC audio as most of
the encoders have had a license making FFmpeg unredistributable if
compiled with support for them. The fact that there now exists a
fully open and truly free AAC encoder integrated directly within the
project means a lot to those who wish to use accepted and widespread
standards.
The majority of the work done to bring the encoder up to quality was
started during this year's GSoC by developer Claudio Freire and
Rostislav Pehlivanov. Both continued to work on the encoder with the
latter joining as a developer and mainainer, working on other parts
of the project as well. Also, thanks to Kamedo2 who does comparisons
and tests, the original authors and all past and current contributors
to the encoder. Users are suggested and encouraged to use the encoder
and provide feedback or breakage reports through our bug tracker.
October 13th, 2015, Telepoint & MediaHub are now supporting our
project
A big thank you note goes to our newest supporters: MediaHub and
Telepoint. Both companies have donated a dedicated server with free
of charge internet connectivity. Here is a little bit about them in
their own words:
* Telepoint is the biggest carrier-neutral data center in Bulgaria.
Located in the heart of Sofia on a cross-road of many Bulgarian
and International networks, the facility is a fully featured Tier
3 data center that provides flexible customer-oriented colocation
solutions (ranging from a server to a private collocation hall)
and a high level of security.
* MediaHub Ltd. is a Bulgarian IPTV platform and services provider
which uses FFmpeg heavily since it started operating a year ago.
"Donating to help keep FFmpeg online is our way of giving back to
the community" .
Thanks Telepoint and MediaHub for their support!
September 29th, 2015, GSoC 2015 results
FFmpeg participated to the latest edition of the Google Summer of
Code Project. FFmpeg got a total of 8 assigned projects, and 7 of
them were successful.
We want to thank Google, the participating students, and especially
the mentors who joined this effort. We're looking forward to
participating in the next GSoC edition!
Below you can find a brief description of the final outcome of each
single project.
Basic servers for network protocols, mentee: Stephan Holljes, mentor:
Nicolas George
Stephan Holljes's project for this session of Google Summer of Code
was to implement basic HTTP server features for libavformat, to
complement the already present HTTP client and RTMP and RTSP server
code.
The first part of the project was to make the HTTP code capable of
accepting a single client; it was completed partly during the
qualification period and partly during the first week of the summer.
Thanks to this work, it is now possible to make a simple HTTP stream
using the following commands:
ffmpeg -i /dev/video0 -listen 1 -f matroska \
-c:v libx264 -preset fast -tune zerolatency http://:8080
ffplay http://localhost:8080/
The next part of the project was to extend the code to be able to
accept several clients, simultaneously or consecutively. Since
libavformat did not have an API for that kind of task, it was
necessary to design one. This part was mostly completed before the
midterm and applied shortly afterwards. Since the ffmpeg command-line
tool is not ready to serve several clients, the test ground for that
new API is an example program serving hard-coded content.
The last and most ambitious part of the project was to update
ffserver to make use of the new API. It would prove that the API is
usable to implement real HTTP servers, and expose the points where
more control was needed. By the end of the summer, a first working
patch series was undergoing code review.
Browsing content on the server, mentee: Mariusz Szczepanczyk, mentor:
Lukasz Marek
Mariusz finished an API prepared by the FFmpeg community and
implemented Samba directory listing as qualification task.
During the program he extended the API with the possibility to remove
and rename files on remote servers. He completed the implementation
of these features for file, Samba, SFTP, and FTP protocols.
At the end of the program, Mariusz provided a sketch of an
implementation for HTTP directory listening.
Directshow digital video capture, mentee: Mate Sebok, mentor: Roger
Pack
Mate was working on directshow input from digital video sources. He
got working input from ATSC input sources, with specifiable tuner.
The code has not been committed, but a patch of it was sent to the
ffmpeg-devel mailing list for future use.
The mentor plans on cleaning it up and committing it, at least for
the ATSC side of things. Mate and the mentor are still working trying
to finally figure out how to get DVB working.
Implementing full support for 3GPP Timed Text Subtitles, mentee:
Niklesh Lalwani, mentor: Philip Langdale
Niklesh's project was to expand our support for 3GPP Timed Text
subtitles. This is the native subtitle format for mp4 containers, and
is interesting because it's usually the only subtitle format
supported by the stock playback applications on iOS and Android
devices.
ffmpeg already had basic support for these subtitles which ignored
all formatting information - it just provided basic plain-text
support.
Niklesh did work to add support on both the encode and decode side
for text formatting capabilities, such as font size/colour and
effects like bold/italics, highlighting, etc.
The main challenge here is that Timed Text handles formatting in a
very different way from most common subtitle formats. It uses a
binary encoding (based on mp4 boxes, naturally) and stores
information separately from the text itself. This requires additional
work to track which parts of the text formatting applies to, and
explicitly dealing with overlapping formatting (which other formats
support but Timed Text does not) so it requires breaking the
overlapping sections into separate non-overlapping ones with
different formatting.
Finally, Niklesh had to be careful about not trusting any size
information in the subtitles - and that's no joke: the now infamous
Android stagefright bug was in code for parsing Timed Text subtitles.
All of Niklesh's work is committed and was released in ffmpeg 2.8.
libswscale refactoring, mentee: Pedro Arthur, mentors: Michael
Niedermayer, Ramiro Polla
Pedro Arthur has modularized the vertical and horizontal scalers. To
do this he designed and implemented a generic filter framework and
moved the existing scaler code into it. These changes now allow
easily adding removing, splitting or merging processing steps. The
implementation was benchmarked and several alternatives were tried to
avoid speed loss.
He also added gamma corrected scaling support. An example to use
gamma corrected scaling would be:
ffmpeg -i input -vf scale=512:384:gamma=1 output
Pedro has done impressive work considering the short time available,
and he is a FFmpeg committer now. He continues to contribute to
FFmpeg, and has fixed some bugs in libswscale after GSoC has ended.
AAC Encoder Improvements, mentee: Rostislav Pehlivanov, mentor:
Claudio Freire
Rostislav Pehlivanov has implemented PNS, TNS, I/S coding and main
prediction on the native AAC encoder. Of all those extensions, only
TNS was left in a less-than-usable state, but the implementation has
been pushed (disabled) anyway since it's a good basis for further
improvements.
PNS replaces noisy bands with a single scalefactor representing the
energy of that band, gaining in coding efficiency considerably, and
the quality improvements on low bitrates are impressive for such a
simple feature.
TNS still needs some polishing, but has the potential to reduce
coding artifacts by applying noise shaping in the temporal domain
(something that is a source of annoying, notable distortion on
low-entropy bands).
Intensity Stereo coding (I/S) can double coding efficiency by
exploiting strong correlation between stereo channels, most effective
on pop-style tracks that employ panned mixing. The technique is not
as effective on classic X-Y recordings though.
Finally, main prediction improves coding efficiency by exploiting
correlation among successive frames. While the gains have not been
huge at this point, Rostislav has remained active even after the
GSoC, and is polishing both TNS and main prediction, as well as
looking for further improvements to make.
In the process, the MIPS port of the encoder was broken a few times,
something he's also working to fix.
Animated Portable Network Graphics (APNG), mentee: Donny Yang,
mentor: Paul B Mahol
Donny Yang implemented basic keyframe only APNG encoder as the
qualification task. Later he wrote interframe compression via various
blend modes. The current implementation tries all blend modes and
picks one which takes the smallest amount of memory.
Special care was taken to make sure that the decoder plays correctly
all files found in the wild and that the encoder produces files that
can be played in browsers that support APNG.
During his work he was tasked to fix any encountered bug in the
decoder due to the fact that it doesn't match APNG specifications.
Thanks to this work, a long standing bug in the PNG decoder has been
fixed.
For latter work he plans to continue working on the encoder, making
it possible to select which blend modes will be used in the encoding
process. This could speed up encoding of APNG files.
September 9th, 2015, FFmpeg 2.8
We published release 2.8 as new major version. It contains all
features and bug fixes of the git master branch from September 8th.
Please see the changelog for a list of the most important changes.
We recommend users, distributors and system integrators to upgrade
unless they use current git master.
August 1st, 2015, A message from the FFmpeg project
Dear multimedia community,
The resignation of Michael Niedermayer as leader of FFmpeg yesterday
has come by surprise. He has worked tirelessly on the FFmpeg project
for many years and we must thank him for the work that he has done.
We hope that in the future he will continue to contribute to the
project. In the coming weeks, the FFmpeg project will be managed by
the active contributors.
The last four years have not been easy for our multimedia community -
both contributors and users. We should now look to the future, try to
find solutions to these issues, and to have reconciliation between
the forks, which have split the community for so long.
Unfortunately, much of the disagreement has taken place in
inappropriate venues so far, which has made finding common ground and
solutions difficult. We aim to discuss this in our communities online
over the coming weeks, and in person at the VideoLAN Developer Days
in Paris in September: a neutral venue for the entire open source
multimedia community.
The FFmpeg project.
July 4th, 2015, FFmpeg needs a new host
UPDATE: We have received more than 7 offers for hosting and servers,
thanks a lot to everyone!
After graciously hosting our projects (FFmpeg, MPlayer and rtmpdump)
for 4 years, Arpi (our hoster) has informed us that we have to secure
a new host somewhere else immediately.
If you want to host an open source project, please let us know,
either on ffmpeg-devel mailing list or irc.freenode.net #
ffmpeg-devel.
We use about 4TB of storage and at least 4TB of bandwidth / month for
various mailing lists, trac, samples repo, svn, etc.
March 16, 2015, FFmpeg 2.6.1
We have made a new major release (2.6) and now one week afterward

from the 6th March. Please see the Release Notes for a list of
note-worthy changes.
We recommend users, distributors and system integrators to upgrade
unless they use current git master.
March 4, 2015, Google Summer of Code
FFmpeg has been accepted as a Google Summer of Code Project. If you
wish to participate as a student see our project ideas page. You can
already get in contact with mentors and start working on
qualification tasks. Registration at Google for students will open
March 16th. Good luck!
March 1, 2015, Chemnitzer Linux-Tage
We happily announce that FFmpeg will be represented at Chemnitzer
Linux-Tage (CLT) in Chemnitz, Germany. The event will take place on
21st and 22nd of March.
More information can be found here
We demonstrate usage of FFmpeg, answer your questions and listen to
your problems and wishes. If you have media files that cannot be
processed correctly with FFmpeg, be sure to have a sample with you so
we can have a look!
For the first time in our CLT history, there will be an FFmpeg
workshop! You can read the details here. The workshop is targeted at
FFmpeg beginners. First the basics of multimedia will be covered.
Thereafter you will learn how to use that knowledge and the FFmpeg
CLI tools to analyse and process media files. The workshop is in
German language only and prior registration is necessary. The
workshop will be on Saturday starting at 10 o'clock.
We are looking forward to meet you (again)!
December 5, 2014, FFmpeg 2.5
We have made a new major release (2.5) It contains all features and
bugfixes of the git master branch from the 4th December. Please see
the Release Notes for a list of note-worthy changes.
We recommend users, distributors and system integrators to upgrade
unless they use current git master.
October 10, 2014, FFmpeg is in Debian unstable again
We wanted you to know there are FFmpeg packages in Debian unstable
again. A big thank-you to Andreas Cadhalpun and all the people that
made it possible. It has been anything but simple.
Unfortunately that was already the easy part of this news. The bad
news is the packages probably won't migrate to Debian testing to be
in the upcoming release codenamed jessie. Read the argumentation over
at Debian.
However things will come out in the end, we hope for your continued
remarkable support!
October 8, 2014, FFmpeg secured a place in OPW!
Thanks to a generous 6K USD donation by Samsung (Open Source Group),
FFmpeg will be welcoming at least 1 "Outreach Program for Women"
intern to work with our community for an initial period starting
December 2014 (through March 2015).
We all know FFmpeg is used by the industry, but even while there are
countless products building on our code, it is not at all common for
companies to step up and help us out when needed. So a big thank-you
to Samsung and the OPW program committee!
If you are thinking on participating in OPW as an intern, please take
a look at our OPW wiki page for some initial guidelines. The page is
still a work in progress, but there should be enough information
there to get you started. If you, on the other hand, are thinking on
sponsoring work on FFmpeg through the OPW program, please get in
touch with us at opw@ffmpeg.org. With your help, we might be able to
secure some extra intern spots for this round!

July 29, 2014, Help us out securing our spot in OPW
Following our previous post regarding our participation on this
year's OPW (Outreach Program for Women), we are now reaching out to
our users (both individuals and companies) to help us gather the
needed money to secure our spot in the program.
We need to put together 6K USD as a minimum but securing more funds
would help us towards getting more than one intern.
You can donate by credit card using Click&Pledge and selecting the
"OPW" option. If you would like to donate by money transfer or by
check, please get in touch by e-mail and we will get back to you with
instructions.
Thanks!
July 20, 2014, New website
The FFmpeg project is proud to announce a brand new version of the
website made by db0. While this was initially motivated by the need
for a larger menu, the whole website ended up being redesigned, and
most pages got reworked to ease navigation. We hope you'll enjoy
browsing it.

July 3, 2014, FFmpeg and the Outreach Program For Women
FFmpeg has started the process to become an OPW includer organization
for the next round of the program, with internships starting December
9. The OPW aims to "Help women (cis and trans) and genderqueer to get
involved in free and open source software". Part of the process
requires securing funds to support at least one internship (6K USD),
so if you were holding on your donation to FFmpeg, this is a great
chance for you to come forward, get in touch and help both the
project and a great initiative!
We have set up an email address you can use to contact us about
donations and general inquires regarding our participation in the
program. Hope to hear from you soon!

a sample with you so we can have a look!
More information about LinuxTag can be found here
We are looking forward to see you in Berlin!
April 18, 2014, OpenSSL Heartbeat bug
Our server hosting the Trac issue tracker was vulnerable to the
attack against OpenSSL known as "heartbleed". The OpenSSL software
library was updated on 7th of April, shortly after the vulnerability
was publicly disclosed. We have changed the private keys (and
certificates) for all FFmpeg servers. The details were sent to the
mailing lists by Alexander Strasser, who is part of the project
server team. Here is a link to the user mailing list archive .
We encourage you to read up on "OpenSSL heartbleed". It is possible
that login data for the issue tracker was exposed to people
exploiting this security hole. You might want to change your password
in the tracker and everywhere else you used that same password.

Linux-Tage' in Chemnitz, Germany. The event will take place on 15th
and 16th of March.
More information can be found here
We invite you to visit us at our booth located in the Linux-Live

February 9, 2014, trac.ffmpeg.org / trac.mplayerhq.hu Security Breach
The server on which FFmpeg and MPlayer Trac issue trackers were
installed was compromised. The affected server was taken offline and
has been replaced and all software reinstalled. FFmpeg Git, releases,
FATE, web and mailinglists are on other servers and were not
affected. We believe that the original compromise happened to a
server, unrelated to FFmpeg and MPlayer, several months ago. That
server was used as a source to clone the VM that we recently moved
Trac to. It is not known if anyone used the backdoor that was found.
We recommend all users to change their passwords. Especially users
who use a password on Trac that they also use elsewhere, should
change that password at least elsewhere.
November 12, 2013, FFmpeg RFP in Debian
Since the splitting of Libav the Debian/Ubuntu maintainers have
followed the Libav fork. Many people have requested the packaging of
ffmpeg in Debian, as it is more feature-complete and in many cases
less buggy.
Rogerio Brito, a Debian developer, has proposed a Request For Package
(RFP) in the Debian bug tracking system.
Please let the Debian and Ubuntu developers know that you support
packaging of the real FFmpeg! See Debian ticket #729203 for more
details.
