Original code

This repo is originally forked from the excellent work of meh. link:https://github.com/meh/rust-ffmpeg-sys[]

Supported versions

Version of this crate corresponds version of ffmpeg it build with. Currently it is 4.2.2.

Building

To build with locally installed ffmpeg libraries you'll need a working pkg-config. I use it on Debian Buster without any problems.

To build with bundled ffmpeg sources when system installed ffmpeg is not available, you'll need yasm installed.
