Ffmpeg exe что это
FFmpeg only provides source code. Below are some links that provide it already compiled and ready to go.
Linux Packages
Linux Static Builds
Windows EXE Files
macOS
You can retrieve the source code through Git by using the command:
FFmpeg has always been a very experimental and developer-driven project. It is a key component in many multimedia projects and has new features added constantly. Development branch snapshots work really well 99% of the time so people are not afraid to use them.
Since FFmpeg is developed with Git, multiple repositories from developers and groups of developers are available.
All FFmpeg releases are cryptographically signed with our public PGP key and should be verified for authenticity.
Approximately every 6 months the FFmpeg project makes a new major release. Between major releases point releases will appear that add important bug fixes but no new features. Note that these releases are intended for distributors and system integrators. Users that wish to compile from source themselves are strongly encouraged to consider using the development branch (see above), this is the only version on which FFmpeg developers actively work. The release branches only cherry pick selected changes from the development branch, which therefore receives much more and much faster bug fixes such as additional features and security patches.

мои заметки на полях
ffmpeg для начинающих
В данной статье попробуем «на пальцах» объяснить, что такое FFmpeg для начинающих пользователей Linux (да и Windows тоже). FFmpeg популярный набор программ и библиотек среди multimedia и web разработчиков. На базе FFmpeg сделано множество программ по конвертированию видео из одного формата в другой. Популярность этой программы крайне высока. Почему он так популярен? Для чего его чаще используют? Как установить и как запустить?
Итак, основные фишки FFmpeg, которые могут привлечь внимание неискушенного Linux пользователя, только-только начавшего изучать Ubuntu:
FFmpeg доступен на Linux, Windows, Mac Os. И везде работает одинаково. Так что, если вы научились работать с FFmpeg под Windows, то точно так же его надо запускать и в Linux и наоборот.
FFmpeg абсолютно самодостаточен. Для того чтобы посмотреть фильм нет необходимости искать в сети, скачивать и устанавливать кодеки. Достаточно всего лишь одного файла (ffplay.exe), все кодеки содержатся внутри этого файла.
FFmpeg — бесплатный софт (лицензии GPL 2.0 и LGPL 2.1) и вы можете использовать его код в своих проектах, как в коммерческих, так и в свободно-распространяемых.
Из чего состоит FFmpeg
Как было уже сказано, FFmpeg — это набор программ. Что значит “набор программ”? Нужно все программы качать или можно по отдельности? Что там внутри? На эти вопросы мы сейчас и постараемся ответить.
Но для начала определимся с термином FFmpeg — это сокращенное от Fast Forward Mpeg. Когда говорим о FFmpeg, как о наборе программ, то первые две буквы «F» должны быть большие (FF).
Итак, FFmpeg состоит из следующих инструментов (tools): ffmpeg, ffplay, ffserver, ffprobe (заметьте, все с маленькой буквы). Для Windows это обычные exe файлы. Причем размер у них очень внушительный. Все дело в том, что все видео и аудио кодеки уже находятся внутри них. Если вам нужно посмотреть фильм, то просто скачайте из сети ffplay.exe, больше ничего не потребуется. Никаких инсталляторов, никаких кодеков, права Administrator не нужны. Скачали, разархивировали, можете приступать к просмотру фильма.
FFmpeg в Windows, размер каждого файла 38-39Mb, все кодеки скомпилированы и прилинкованы «внутрь» исполняемого файла.
ffmpeg
С помощью этой программы можно конвертировать видео из одного формата в другой. Склеивать несколько видеороликов в один. Разбирать видео на отдельные кадры (изображения), а потом склеивать обратно. Ускорять/замедлять, масштабировать, добавлять субтитры и несколько звуковых дорожек. И еще 100500 полезных действий.
Список доступных опций этой команды занимает 203 страницы:
Впечатляет, не так ли?
ffplay
Используется для просмотра фильмов. Если вы начинаете знакомство с FFmpeg с просмотра фильмов, то ffplay, то что вам нужно. На начальном этапе весь пакет FFmpeg для начинающих сводится к использованию лишь этой программы.
ffserver
Если вам вдруг захотелось создать свой видео хостинг похожий на YouTube, то используйте ffserver.
ffprobe
Волшебная программа, расскажет вам все о фильме, который вы скачали (формат, продолжительность, сколько звуковых дорожек и многое другое). Выдаст на экран столько информации о фильме, что потребуется полдня, чтобы все это прочитать.
Помимо четырех программ в пакет FFmpeg входит еще и набор свободно-распространяемых библиотек (из которых вышеприведенные программы и собраны):
В принципе, из-за этих библиотек весь проект FFmpeg и затевался, а программы уже так, бонусом пошли 🙂
Используя эти библиотеки вы можете создавать свои приложения по работе с мультимедиа контентом и даже потом продавать их. Написать свой видеоплеер или видеоконвертер не составит труда. В сети полно руководств и инструкций по использованию библиотек FFmpeg.
История
История развития FFmpeg так же богата, как и его содержимое. Начавшись в 2000 году она претерпела сильное потрясение в 2011, когда часть разработчиков решила создать свою собственную библиотеку по работе с медиа контентом, назвали они ее — Libav. Свое желание уйти из проекта они объяснили недовольством организацией проекта FFmpeg, где по сути вся власть находилась в руках одного человека и все решения принимал только он сам.
Сейчас Libav идет своим путем и никого не слушает. Код обновляется не так часто, как FFmpeg. Каждое обновление тщательно проверяется.
FFmpeg в долгу не остался и исправно, каждые два дня, забирает к себе в норку изменения в коде, сделанные командой Libav:-)
В настоящее время FFmpeg продолжает активно развиваться, как доказательство скриншот репозитария исходных кодов:
Установка
Пакет FFmpeg настолько популярен, что включен во многие дистрибутивы Linux по умолчанию. Если вы по какой-то причине не установили его сразу, то это можно сделать потом с помощью менеджера пакетов. Установка FFmpeg для начинающих не должна вызвать особых проблем. В зависимости от дистрибутива Linux, нужно будет выполнить ряд стандартных команд.
Ubuntu
CentOS
openSuSe
Windows
Самые свежие версии FFmpeg для Windows можно скачать с:
Два типа FFmpeg
Есть два вида в которых FFmpeg приходит на ваш компьютер:
1) static-build — в этом случае все кодеки, фильтры и утилиты вкомпилированы «внутрь» ffmpeg.exe (ffprobe.exe, ffplay.exe) и вам достаточно скачать только один из этих файлов, чтобы начать смотреть киношку (ffplay.exe). В этом случае размер исполняемого модуля сильно раздувается (до 39Mb). Зато очень удобно.
2) shared-build — здесь кодеки, фильтры и другие вспомогательные программки являются самостоятельными отдельными файлами, которые FFmpeg находит и по мере надобности подгружает. В этом случае размер исполняемого модуля всего 190Kb.
Если вы устанавливаете FFmpeg в Linux, то с вероятностью 99.9% будет установлен shared-build.
Лично я, предпочитаю static-build (не надо думать о других библиотеках). Чтобы получить static-build под Linux нужно собрать FFmpeg самому из исходников. Для начинающих пользователей Linux это может оказаться сложно.
А как смотреть кино?
Все понятно, но как фильмы-то смотреть? Как говорилось выше, ffplay (ffplay.exe — под Windows) является консольной программой, то есть у нее нет графического интерфейса. Для просмотра видео необходимо выполнить в командной строке:
после чего сразу начинает воспроизводиться фильм:
Для начинающего пользователя такой способ запуска фильма может показаться необычным. Но в этом-то вся и мощь ffplay. У него такое же огромное количество опций, как и у ffmpeg, которы помогут настроить картинку для самых взыскательных ценителей кино.
Если вы чувствуете себя неуверенно при работе с командной строкой Windows, то можете воспользоваться следующим способом. Захватите фильм мышкой и перетащите его на ffplay.exe, кино сразу же станет воспроизводиться.
Контроль за воспроизведением (краткий список команд):
q, ESC — выход,
f — полный экран (двойной клик левой кнопкой мыши),
p — поставить на паузу,
m — звук вкл/выкл,
9, 0 — звук прибавить/убавить,
t — переключение субтитров,
c — cycle program
s — покадровое перемещение по фильму,
стрелка влево/вправо — перемещение на 10 сек назад/вперед,
стрелка вниз/вверх — перемещение на 1 мин назад/вперед,
page down/page up — перемещение на 10 мин назад/вперед.
Графический интерфейс проигрывателя ffplay выглядит довольно аскетичным, вернее сказать его вообще нет. Отсутствуют привычные ползунки, кнопочки, менюшки присущие media player’ам с графическим интерфейсом. При работе с ffplay вы видите только сам фильм и какие-то непонятные цифры и слова мелькающие в окне терминала, как в фильме «Матрица». На самом деле управлять фильмом с клавиатуры просто и понятно, через несколько просмотров пальцы сами запомнят какие кнопки нужно нажимать.
Несколько примеров запуска ffplay с различными опциями:
Уменьшить изображение в 4 раза по ширине
Почистить видео от шума
Ускорение в 2 раза
А как перекодировать?
Перевести mpg в avi
Извлечь звук из видео и записать в формате MP3
Склеить звук и видео
Извлечь видеодорожку (без звука)
Изменить размер видео
Выбросить первые 45 секунд видео и оставить участок длительностью 40 секунд
Перекодировать WAV в MP3
Разложить видео на кадры (изображения)
Сделать видео из набора изображений
Заключение
Данная статья имеет целью познакомить читателя с мощнейшим набором программ FFmpeg. Дается краткое описание пакета FFmpeg. Приводятся примеры его использования для просмотра видео и для обработки (ковертиования) аудио и видео материалов.
Перечислена только малая часть возможностей пакета FFmpeg. Для первого ознакомления я думаю достаточно. Остались за кадром такие FFmpeg фичи, как многопроходное кодирование, фильтры и цепочки фильтров, связка с Avisynth, сборка FFmpeg со сторонними кодеками.
Задачей данной статьи было показать, что FFmpeg для начинающих пользователей Linux должен быть незаменимым инструментом при работе с media контентом. Не нужно бояться отсутствия GUI. Работа с аудио и видео из консоли тоже может быть очень эффективной.
Давно думал опубликовать FFmpeg на нашем проекте и вот добрался до этой программы. Сразу напишу, что понравится она достаточно узкому кругу людей из-за своей сложности и отсутствия графического интерфейса. Но все остальные, кто понимает как ей пользоваться, смогут без проблем конвертировать аудио и видео файлы, а также совершать другие операции о которых поговорим чуть ниже.
Сразу отмечу, что FFmpeg частенько обновляется, так как разработчики пытаются идти в ногу со временем, они всегда добавляют новые настройки и функции, делают все, чтобы опытный пользователь смог получить максимум от работы. Вы сможете потратить огромное количество времени возясь с настройками программы, вы сможете настроить огромное количество профилей для совершенно любых ситуаций, вы сможете работать с большим количеством видео форматов к которым можно отнести VI, FLV, MKV, MPEG и многие другие.
Большое количество известных видео плееров для работы используют FFmpeg, например всем известный VLC или MPlayer. Я выше писал, что расскажу подробнее о всех возможностях этого набора свободных библиотек, помимо конвертирования, вы сможете также вести запись и передачу цифровых аудио и видео материалов в сеть. Данный пакет включает в себя известную библиотеку кодирования и декодирования libavcodec, а также библиотеку мультиплексирования и демультиплексирования под названием libavformat.
В целом вот и все, что мне хотелось написать про данный продукт, я думаю все, кто имеет отношение к видео, занимается конвертированием, тонкой настройкой, знаком с FFmpeg, буду стараться следить за обновлениям, чтобы у вас под рукой всегда была свежая версия данного пакета, а скачать его бесплатно вы сможете ниже, а список команд посмотреть рекомендую через вызов помощи, об этом я писал раньше уже, смысла нет копировать все и вставлять сюда, спасибо за внимание!

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.
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)
JГЎn SebechlebskГЅ’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 JГЎn 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»
FFmpeg 3.1 «Laplace», a new major release, is now available! Some of the highlights:
We strongly recommend users, distributors, and system integrators to upgrade unless they use current git master.
March 16th, 2016, Google Summer of Code
FFmpeg has been accepted as a Google Summer of Code open source 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:
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.
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.
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:
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 SzczepaЕ„czyk, 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.
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.
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:
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 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.
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.

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!

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.
RogГ©rio 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.
