"A "library" means a collection of software functions and/or data
prepared so as to be conveniently linked with application programs
(which use some of those functions and data) to form executables."
It has been controversial in the past that ffmpeg.c/ffplay.c/ffserver.c
have the LGPL license header because it does not make an obvious sense.
However someone could copy ffmpeg.c under the terms of LGPL and make it
But "as is" ffmpeg.c without modifications cannot be considered a "Library"
