Clearly the licensing situation isn't confusing enough. I don't know why that guy insists on LGPLv3.

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:
|
|
- everything under etc/ is unknown
|
|
- everything under DOCS/man/ is GPLv2+
|
|
- sub/osd_font.otf is LGPLv2.1+
|
|
- some tests under waftools/fragments/ might be GPLv2+
|
|
- version.sh is GPLv2+
|
|
|
|
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+.
