Ffmpeg для mac os
There are a few ways to get FFmpeg on macOS:
- Use a package manager like Homebrew or MacPorts to install ffmpeg . These will automatically keep your FFmpeg installation up-to-date. See the Homebrew section below for more info.
- Download a static build for macOS. This is as easy as extracting and running the downloaded binary. One disadvantage with static builds is that updates have to be performed manually. Also, they may not contain all encoders or filters you want.
- Build it yourself. Compiling on macOS is as easy as on any other *nix machine. Download the source, then run ./configure with the needed flags, make and make install . However, the configuration options have to be set manually, and you will need to install third-party libraries yourself. See the compilation section below for more info.
ffmpeg through Homebrew
Homebrew is a command-line package manager, which is similar to apt-get on popular Linux distributions. In order to use it, you need to install brew first, if you haven’t already:
Follow the on-screen instructions. This will take a few minutes while it’s installing the necessary developer tools for macOS. Then, run:
to get the latest released version with minimal configuration (and library dependency) options. These versions are packaged as Homebrew formulas and will take care of all the dependencies and the installation itself. To get the latest Git master version, run:
Additional options
Since v2.0, Homebrew does not offer options for its core formulae anymore. Users who want to build ffmpeg with additional libraries (including non-free ones) need to use so-called taps from third party repositories. These repositories are not maintained by Homebrew.
The following repositories for ffmpeg are available – refer to the README for additional information about the included options:
ffmpeg can be installed from the repository using its full formula name after tapping, for example:
Options are available with brew options homebrew-ffmpeg/ffmpeg/ffmpeg .
Updating ffmpeg
To later upgrade your ffmpeg version to the latest released, simply run:
If you have installed the HEAD, then you can upgrade by running:
Compiling FFmpeg yourself
Xcode
Xcode is required to compile software on your Mac. Install Xcode by downloading it from the website or using the Mac App Store.
After installing Xcode, install the Command Line Tools from Preferences > Downloads > Components. You can also install the tools via your shell:
Installing dependencies with Homebrew
To get some dependencies for ffmpeg, you can install Homebrew.
Tip: If you don’t want to use Homebrew to get the dependencies, see the section below. Using Homebrew will however save you time in setting up all the needed tools.
Manual install of the dependencies without Homebrew
Pkg-config & GLib
Pkg-config is necessary for detecting some of the libraries you can compile into FFmpeg, and it requires GLib, which is not included in macOS (but almost every other *nix distribution). You may either download pkg-config 0.23, or download the large tarball from Gnome.org and compile it. Pkg-config is available from Freedesktop.org.
To compile GLib, you must also download gettext from GNU.org and edit the file stpncpy.c to add #undef stpncpy just before #ifndef weak_alias . Mac OS X Lion has its own (incompatible) version of the stpncpy function, which overlaps in gettext . Compile gettext as usual. Compile GLib with
To compile pkg-config, run
Nasm is an assembler required for x264. The latest version is available at nasm.us.
Additional libraries
These are just some examples. Run ./configure —help for all available options.
- x264 encodes H.264 video. Use —enable-gpl —enable-libx264 .
- fdk-aac encodes AAC audio. Use —enable-libfdk-aac .
- libvpx is a VP8 and VP9 encoder. Use —enable-libvpx .
- libvorbis encodes Vorbis audio . Requires libogg. Use —enable-libvorbis .
- libopus encodes Opus audio.
- LAME encodes MP3 audio. Use —enable-libmp3lame .
- libass is a subtitle renderer. Use —enable-libass .
Freetype
macOS already comes with freetype installed (older versions may need X11 selected during installation), but in an atypical location: /opt/X11/ .
Running freetype-config in Terminal can give the locations of the individual folders, like headers, and libraries, so be prepared to add lines like
in your ./configure command.
Compiling
Once you have compiled all of the codecs/libraries you want, you can now download the FFmpeg source either with Git or the from release tarball links on the website.
For general instructions on how to compile software, consult the Generic compilation guide. The information there is applicable to the macOS environment as well.
Run ./configure —help , and study its output to learn what options are available. Make sure you’ve enabled all the features you want. Note that —enable-nonfree and —enable-gpl will be necessary for some of the dependencies above.

FFmpeg only provides source code. Below are some links that provide it already compiled and ready to go.
Linux Packages

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.
To verify a release:
- Import our public key into your local keyring:
- Download a release tarball and its corresponding signature.
- Verify the signature:
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.

Installing FFmpeg for Mac
Audacity on Mac is now a 64-bit application. |
This means that if you are a user of previous Audacity versions on Mac and had installed the optional FFmpeg library then you must now install the 64-bit versions of the FFmpeg library, otherwise your imports and exports that depend upon FFmpeg will no longer work.
Installing the 64-bit FFmpeg library will not overwrite or delete your 32-bit FFmpeg library if you have one installed.
Contents
Recommended package installer
- Go to the external download page
Left-click this link, do not right-click. - In the 64-bit FFmpeg section, left-click the link «ffmpeg_64bit_osx.pkg» and save the file anywhere on your computer.
- When you have finished downloading, double-click the «ffmpeg_64bit_osx.pkg» in your Downloads folder.
- You will be guided through the installation
- Click through the steps in the installer. This will install the ffmpeg.55.64bit.dylib file in the system library at /Library/Application Support/audacity/libs/.
- On some Macs the process may look as though it has stalled on «Validating packages» — just be patient and wait for it to complete.
- Restart Audacity if it was running when you installed FFmpeg then Audacity should detect FFmpeg automatically.
If you have problems with Audacity detecting FFmpeg, follow the steps below to manually locate FFmpeg.
Locating the FFmpeg library manually
If you installed FFmpeg while Audacity was running, or if you installed FFmpeg to a non-default location, Audacity will ask you to configure Preferences to locate the FFmpeg library.
To do this, access Preferences then the «Libraries» tab on the left:
As in the image above, the «FFmpeg Library Version» will say «FFmpeg library not found«. To correct this:
- Click the Locate. button to right of FFmpeg Library:
- If a «Success» message indicates Audacity has now automatically detected valid FFmpeg libraries and asks if you want to detect them manually, click No , then OK to close Preferences
- If the «Locate FFmpeg» dialog appears, click Browse.
- Navigate to the folder that contains FFmpeg and select the file «ffmpeg.55.64bit.dylib«
- Click Open then OK
- Note that the FFmpeg library has been located
- Then click OK to close Preferences.
FFmpeg Library Version should now show a set of three version numbers for the sub-libraries of FFmpeg («F» for libavformat version, «C» for libavcodec version and «U» for libavutil version).
If you still see «not found», you may have installed the wrong libraries. Click the Download. button to obtain the correct library for your operating system. You can also choose Help > Diagnostics > Show Log. to see diagnostic information about FFmpeg detection.

Установка FFmpeg на OS X
есть ли хорошее место или сценарий bash, который я могу использовать (или, по крайней мере, версия, которую я могу построить сам) для FFmpeg на OS X?
У меня установлен Xcode, а также CLI для Xcode ( gcc и т. д.).
У меня установлена версия FFmpeg, но каким-то образом я получаю ошибку сегментации на libx264, а также libvpx (я не могу конвертировать в MP4 и WebM).
все, что я хочу сделать, это Пакетное преобразование видеофайлов в совместимые с HTML5 Видео. Все мои исходные видео состоят из. мов .mp4 и .файл WMV. .кстати, ogv отлично работает.
Итак реальный вопрос:
- Как удалить все FFmpeg на моем Mac сейчас
- переустановить его версию, которая может конвертировать .МР4, .WebM и .ogv
Я также пробовал предварительно скомпилированную версию Miro Video converter, но почему-то это тоже не работает.

есть три варианта, отсортированный по сложности:
- Homebrew (или другие пакетные менеджеры)
- статический строит
- скомпилировать себя
чтобы следовать этому, вы должны иметь немного знаний, используя терминал / оболочки под OS X.
1. Доморощенный
доморощенного имеет формулу для стабильных выпусков FFmpeg. Это позволит вам работать довольно быстро. Во-первых, установите Доморощенного путем открытия терминал.app и вставляем это. Внимательно следуйте всем инструкциям!
затем установите FFmpeg через ffmpeg формула:
это загрузит много зависимостей, таких как x264, но после этого вы должны быть хорошо идти.
дополнительные параметры, проверьте вывод brew info ffmpeg . Вы можете, например, добавить следующие опции, которые обычно отключены:
в обновите ffmpeg позже, выполните:
2. Статические Сборки
проект FFmpeg, on страница скачать, предлагает ссылки на статические сборки для ffmpeg , который вы можете просто скачать, распаковать и использовать в терминале.
на данный момент, Вы можете получить их от здесь:
статические сборки не могут содержать все возможные кодировщики, в основном из-за проблем с лицензированием. Вот почему я не рекомендую использовать их, если вы действительно не заботитесь о том, какие конкретные функции вам нужны.
после загрузки, извлеките файл, откройте терминал.app, и перейдите в каталог, где вы разархивированные файлы, то есть, где вы найдете файл с именем ffmpeg . Скопируйте этот файл в /usr/local/bin :
теперь, если вы используете Bash (который является оболочкой по умолчанию), добавьте его в свой $PATH:
добавить в конец файла:
сохранить и закрыть редактор. Теперь перезагрузите терминал и which ffmpeg должен возвратить /usr/local/bin/ffmpeg .
3. Компиляция себя
вы можете, конечно, построить ffmpeg инструменты сами, следуя руководство по компиляции OS X. Это руководство всегда будет в актуальном состоянии, и путем ручной компиляции вы сможете настроить несколько параметров.
чтобы удалить любую версию FFmpeg вы установили, мы должны знать, как вы установили его в первую очередь. Так как Homebrew установим на /usr/local/Cellar , и символическая ссылка на /usr/local/bin/ffmpeg , он, вероятно, не вызовет никаких проблем с другими библиотеками. Однако, проверьте make install сценарии версии вы (якобы) причине себя и увидеть, где они размещены через FFmpeg. Затем просто удалите их оттуда — это не помешает доморощенному.
ошибка сегментации может быть вызвана неправильной связью между библиотеками x264 или libvpx. Поскольку Homebrew позаботится об этом, вы не должны сталкиваться с какими-либо проблемами.
