Licensing of this repository is just a tiny bit more complex than usual, since the libraries can be built in so many different ways and have so many different parts.
Almost everything here is licensed under the GNU Lesser General Public License (LGPL), version 2.1 or later (abbreviated as LGPL-2.1+
).
Specifically, the FFmpeg
source code, all of the build scripts, and the binaries are licensed under the LGPL-2.1+
. Note that care is taken to use only LGPL-2.1+
compatible options when building FFmpeg
.
To ensure compliance, see the online checklist.
A nice summary of LGPL complance is on Stack Overflow.
There also are exceptions in the tools
directory, which just mirrors external tools that either are used or have been used developing this build. Please see the individual files and subdirectories there for specific licenses.
