2DESCRIPTION = "Libav is a friendly and community-driven effort to provide its users \
3 with a set of portable, functional and high-performance libraries for \
4 dealing with multimedia formats of all sorts. It originates from the \
5 FFmpeg codebase, but goes its own way these days, providing its users \
6 with reliable releases and a clear vision how to go forward."
