# Static FFmpeg Build
`sffmpeg` is a simple CMake-based full-featured FFmpeg build helper.

It currently works on Linux and other POSIX systems (with a few tweaks). It has been tested the most heavily on Linux/x86_64
(Ubuntu 18.04). This helper is regularly updated with the latest versions of the FFmpeg dependencies, and provides an effective
way to build, test and compare multiple versions of FFmpeg on the same machine.

## Build Dependencies
`sffmpeg` requires the following software to be installed in order to build:

- a recent version of [cmake](http://www.cmake.org/) (3.6+)
- a recent version of [gcc/g++](http://gcc.gnu.org/) (7.x+)
- the [autoconf](http://www.gnu.org/software/autoconf/) and [automake](http://www.gnu.org/software/automake/) utilities
- the [pkg-config](http://www.freedesktop.org/wiki/Software/pkg-config/) utility

A dependencies check is automatically performed and the build is aborted if a dependency is missing.

## Usage
Just type the following commands at the shell prompt:

    $ git clone https://github.com/pyke369/sffmpeg
    $ cd sffmpeg
    $ make

Then go grab a coffee (or maybe ten). The helper will compile all FFmpeg dependencies for you. Once done, you should get an
FFmpeg binary in the `build/bin` directory (with all dependencies statically linked-in).

From there, you may use the binary immediately or build a Debian package for later deployment (see below).

## Packaging
(requires the `devscripts` package)

You may optionally build a Debian package by typing the following command at the shell prompt:
```
$ make deb
```

The `ffmpeg`, `ffprobe` and `frmxtract` binaries will be installed by the package in the `/usr/local/bin` directory.
```
$ sudo dpkg -i ../sffmpeg_5.1.2_amd64.deb
