Как установить ffmpeg python
Install ffmpeg in to virtual environment
I am trying to install ffmpeg in order to use it on OpenAI to record videos. I have installed it using brew install ffmpeg but somehow when I compile my code I get the same error, it is like the package is not recognized by my virtualenv where I am working.
Error on Python console:
It seems like that Anaconda for example needs a specific command to install this package into its environment, it is the same for virtualenv?

This is not possible. FFmpeg is a separate application. If you need to use ffmpeg in python, you either need to pip install a wrapper for python (e.g. ffmpeg-python, ffmpy, etc). But those wrappers does not use the full power of FFmpeg.
This is possible. A conda recipe for ffmpeg is available via the menpo or conda-forge channels. Try using this command:
This question is a little old already, but posting my solution because it could help others.
If you don’t use Anaconda (like me) I don’t know of a command to install it automatically for you. However, there is a workaround that may work for you.
Go and download the ffmpeg package you desire (e.g. here). Then place the ffmpeg.exe executable in the same folder as you python file you are running. Then this part of your code will run and you won’t get the error message you described.

Установите python3.7 и получите ffmpeg
1. Установите python3.7.3
1.1 Скачать python
Но когда я зашел на официальный сайт для загрузки, скорость была невысокой. Я нашел хороший ресурс, рекомендованный пользователем сети из Интернета:
1.2 Установите python под windows
Здесь python установлен под Windows, пожалуйста, проверьте следующую страницу: Добавьте Python 3.X в PATH.
Вот фото из интернета.
1.3 Тестовая установка Python
cmd, чтобы открыть командную строку, введите команду: python
Если после выполнения выводится следующий номер версии Python, установка прошла успешно. Введите exit (), чтобы выйти.
2.1 Метод 1: pip3 install you-get
В Интернете говорится, что после установки python вы можете напрямую выполнить эту команду для установки yout-get, но когда я выполняю эту команду здесь, она всегда безуспешна. И это было выполнено дважды, и сообщалось о разных ошибках. следующим образом:
Эти две ошибки должны быть такими же, но второй раз, похоже, имеет дополнительный тайм-аут доступа.
2.2 Загрузите you-get с git и установите вручную
(1) Поместите сжатый пакет в простой путь без английского языка (например, E: \ swd \ you-get-develop) и разархивируйте;
(2) cmd входит в командное окно, команда cd вводит путь к E: \ swd \ you-get-develop;
(3) Выполните команду: python setup.py install
Я выполнил эту команду здесь и сообщил об ошибке:
Конкретная причина ошибки объяснена в приведенной выше цитате URL. Скопируйте следующим образом:
После проверки проблемы выяснилось, что после python3.4 пакет imp, указанный в setup.py, устарел и должен быть заменен пакетом importlib.
Следуйте приведенным ниже инструкциям, чтобы изменить файл E: \ swd \ you-get-develop \ setup.py:
Изменен для импорта os, json, importlib.machinery
(4) После модификации повторно выполните python setup.py install Команда, установка прошла успешно.
2.3 Протестируйте установку
В командной строке cmd выполните команду: you-get
Если выводится следующий большой абзац, установка прошла успешно.
3. Установите ffmpeg
Роль ffmpeg: видео, загруженное с помощью you-get, будет разделено на несколько файлов. После установки ffmpeg оно будет автоматически объединено в один файл, и это здорово.
3.1 Установите ffmpeg
В-третьих: добавьте в переменную окружения: d: / ffmpeg / bin
Установочный пакет на официальном сайте ffmpeg, моя загрузка из Интернета очень медленная и всегда не работает.Я разместил ссылку для общего доступа на облачном диске Baidu.
Общая версия программного обеспечения: ffmpeg-20200101-7b58702-win64-static.zip
Ссылка: https://pan.baidu.com/s/1dt4xuK2QJDl5k8AlEBetHQ
Извлечь код: 1xba
3.2 Проверка установки ffmpeg
cmd входит в окно командной строки и выполняет команду: ffmpeg
Ниже приводится много выводов, указывающих на успешную установку:

Как установить ffmpeg python
ffmpeg-python: Python bindings for FFmpeg
There are tons of Python FFmpeg wrappers out there but they seem to lack complex filter support. ffmpeg-python works well for simple as well as complex signal graphs.
Flip a video horizontally:
Or if you prefer a fluent interface:
Complex filter graphs
Take for example a signal graph that looks like this:
The corresponding command-line arguments are pretty gnarly:
Maybe this looks great to you, but if you’re not an FFmpeg command-line expert, it probably looks alien.
If you’re like me and find Python to be powerful and readable, it’s easier with ffmpeg-python :
ffmpeg-python takes care of running ffmpeg with the command-line arguments that correspond to the above filter diagram, in familiar Python terms.
Real-world signal graphs can get a heck of a lot more complex, but ffmpeg-python handles arbitrarily large (directed-acyclic) signal graphs.
The latest version of ffmpeg-python can be acquired via a typical pip install:
Or the source can be cloned and installed from locally:
When in doubt, take a look at the examples to see if there’s something that’s close to whatever you’re trying to do.
See the Examples README for additional examples.
Special option names:
Multiple inputs:
Filters that take multiple input streams can be used by passing the input streams as an array to ffmpeg.filter :
Multiple outputs:
String expressions:
Expressions to be interpreted by ffmpeg can be included as string parameters and reference any special ffmpeg variable names:
Frequently asked questions
Why did my audio stream get dropped?
This dilemma is intrinsic to ffmpeg, and ffmpeg-python tries to stay out of the way while users may refer to the official ffmpeg documentation as to why certain filters drop audio.
As usual, take a look at the examples (Audio/video pipeline in particular).
How can I find out the used command line arguments?
How do I do XYZ?
Take a look at each of the links in the Additional Resources section at the end of this README. If you look everywhere and can’t find what you’re looking for and have a question that may be relevant to other users, you may open an issue asking how to do it, while providing a thorough explanation of what you’re trying to do and what you’ve tried so far.
Issues not directly related to ffmpeg-python or issues asking others to write your code for you or how to do the work of solving a complex signal processing problem for you that’s not relevant to other users will be closed.
That said, we hope to continue improving our documentation and provide a community of support for people using ffmpeg-python to do cool and exciting things.
One of the best things you can do to help make ffmpeg-python better is to answer open questions in the issue tracker. The questions that are answered will be tagged and incorporated into the documentation, examples, and other learning resources.
If you notice things that could be better in the documentation or overall development experience, please say so in the issue tracker. And of course, feel free to report any bugs or submit feature requests.
Pull requests are welcome as well, but it wouldn’t hurt to touch base in the issue tracker or hop on the Matrix chat channel first.
Anyone who fixes any of the open bugs or implements requested enhancements is a hero, but changes should include passing tests.
