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".

Some libraries are GPLv2+ or GPLv3+ only. Building mpv with Samba support makes
it GPLv3+.

Source files with specific licenses:
- etc/input.conf is LGPLv2.1+
- etc/builtin.conf is LGPLv2.1+
- etc/encoding-profiles.conf is LGPLv2.1+
- everything else under etc/ is unknown
- everything under DOCS/man/ is GPLv2+
- sub/osd_font.otf is LGPLv2.1+
- version.sh is LGPLv2+
- bootstrap.py is unknown (probably GPLv2+ or LGPLv2+)
- wscript: GPLv2+ (due to 98fca3531841221b)

Some files are marked with "Almost LGPL." These files are GPL, but all authors
have agreed to relicense them to LGPL. the problem is that one of the authors is
Michael Niedermayer, who cited the following conditions for relicensing:

  http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2016-September/073535.html

We assume the first 3 conditions are fulfilled. The last condition can be
interpreted as that his code can be changed to LGPL only as soon as the "core"
of mpv changes to LGPL. We interpret "core" as something minimal, that can
actually be built and run, with all GPL code disabled.

Some files are LGPLv3+. This is due to the contributions of a single developer
going by the SVN username "iive". The chosen license of this project is
LGPLv2.1+. The affected files will be changed to LGPLv2.1+ at the earliest
opportunity, for example if his contributions disappear by being replaced
or removed. All new contributions to these files are implied to be LGPLv2.1+.

LGPL relicensing status. Files which require some sort of action to get a basic
LGPL player core (relicensing, replacement, or partial/full rewrites) are marked
with an "x".
