## 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 as a guideline for your command.

#### 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.
