## What is this?



### Project Objective



To facilitate better understanding of FFmpeg through collaborative sharing of useful scripts and detailed flag-level description of how each script works, so archivists can copy-paste and produce their own scripts, but also understand how and why they work.



## How do I see it?



The code is found in the gh-pages branch (the default primary branch). Readme is right here. You can see the site live on [GitHub pages](http://amiaopensource.github.io/ffmprovisr).



You can also install the latest [release](https://github.com/amiaopensource/ffmprovisr/releases) on your computer with the two commands:

```

brew tap amiaopensource/amiaos

brew install ffmprovisr

```

and then call it locally with the command:

```

ffmprovisr

```

This works currently under macOS, Linux and the Linux apps on Windows (Ubuntu and Debian tested). On classic Windows you can install the last [release](https://github.com/amiaopensource/ffmprovisr/releases) manually and the open `index.html` in a browser.



### Parseable list of the commands



A list of all recipes in an easily parseable [ASCII text](recipes.txt) format is provided as well. It contains for each recipe its title and command in the following format:



```

# title of recipe 1

ffmpeg command 1

# title of recipe 2

ffmpeg command 2



...



# title of recipe n-1

ffmpeg command n-1

# title of recipe n

ffmpeg command n

```



The used [one-liner](scripts/get_recipe_list) is in the `scripts` folder.



## How do I contribute?



You are welcome to edit the codebase yourself, or just supply the information and ask it to be added to the site.



### Edit codebase



To contribute to this project directly (and more quickly), clone this repository and create a new branch (`git checkout -b your-branch-name`) and add or modify a new block in `index.html`. Then [submit a pull request](https://github.com/amiaopensource/ffmprovisr/pulls) and the maintainers will review and integrate your code. There is a commented-out sample block available at the bottom of `index.html` that can be a guideline for your command.



#### Guidelines for contributing



* Recipes should ideally do just one thing or solve one problem, to keep things as user-friendly as possible and to avoid unintended side-effects

* Explanations and examples for recipes should be as generic as possible, to allow users to alter the command for their own use-case.

  * This may involve the use of `VARIABLE_NAMES`

  * Example: [Fade video and audio streams](https://amiaopensource.github.io/ffmprovisr/#fade_streams)

* Some recipes may benefit from including a GIF that shows the output

  * Example: [Plays a graphical output showing decibel levels of an input file](https://amiaopensource.github.io/ffmprovisr/#astats)

* Some recipes require an explanatory section which may not fit gracefully into the recipe itself

  * Example: [Rewrap a file](https://amiaopensource.github.io/ffmprovisr/#basic-rewrap)

* Recipes involving `-filter_complex` can be some of the most verbose and difficult to understand, so breaking these down as much as possible into their relevant sections is ideal

  * Example: [Generate two access MP3s from input](https://amiaopensource.github.io/ffmprovisr/#append_mp3)

* Some recipes may refer to a specific standard or vocabulary, and it's useful to link to these so that the user can scale the recipe to their use case

  * Example: [Generate Broadcast WAV](https://amiaopensource.github.io/ffmprovisr/#bwf)



### Make a request



If you are having trouble with coding it yourself or with GitHub, feel free to [submit an issue](https://github.com/amiaopensource/ffmprovisr/issues) with the kind of command you would like to see added to the site.



### General help



If you want to help but don't have a new script to add, you can help us by testing out the scripts available, by refining or clarifying the documentation, or [creating an issue](https://github.com/amiaopensource/ffmprovisr/issues) for anything that sounds confusing and requires clarification.
