mpv/Copyright

mpv is a fork of mplayer2, which is a fork of MPlayer.

mpv as a whole is licensed as GPL version 2 or later (see LICENSE). Most source
files are GPLv2+, but some files are available under a more liberal license,
such as LGPLv2.1+, BSD, MIT, ISC, and possibly others. Look at the copyright
header of each source file, and grep the sources for "Copyright" if you need
to know details. C source files without Copyright notice are licensed as
LGPLv2.1+. Also see the list of files with specific licenses below (not all
files can have a standard license header).

All new contributions must be LGPLv2.1+ licensed, or if the changes are done on
GPL code, must come with the implicit agreement that the project can relicense
the code to LGPLv2.1+ at a later point without asking the contributor. (This
is a safeguard for making potential relicensing of the project to LGPLv2.1+
easier.) Using a more liberal license compatible to LGPLv2.1+ is also ok.

For information about authors and contributors, consult the git log, which
contains the complete SVN and CVS history as well.

Note that mplayer2 as a whole is licensed under GPLv3+. This is because it uses
a copy of talloc (part of Samba), which is LGPLv3+, and the next compatible
license for this mix is GPLv3+.

MPlayer as a whole is licensed under GPLv2 (incompatible to GPLv3!), because
some files are licensed to GPLv2 (and _not_ any later version of the license).
In particular, this affects the file libmpdemux/demux_ty_osd.c. It is disabled
under mplayer2, and has been removed from mpv.

"v2.1+" in this context means "version 2.1 or later".
