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.
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).
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.
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:
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
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.
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.
