As usual, the history of these files is a bit murky. It starts with the initial commit. (At which some development had already been done, according to the AUTHORS and ChangeLog files at the time, we should be but covered with relicensing agreements, though.) then it goes on with complete lack of modularization, which was cleaned up later (cd68e161). As usual, we don't consider the copyright of the stuff that has been moved out cleanly. There were also contributions to generic code by people who could not be reached or who did not agree to the relicensing, but this was all removed. The only patches that we could not relicense and which were still in the current code in some form are from Dénes Balatoni:422b0d2a,32937181. We could not reach him, so commitsf34e1a0dand18905298remove his additions. It still leaves the demux_control() declaration itself, but we don't consider it copyrightable. It's basically an idiom that existed in MPlayer before that change, applied to the demuxer struct. (We even went as far as making sure to remove all DEMUXER_CTRLs the original author added.) Commitbe54f481might be a bit of a corner case, but this was rewritten, and we consider the old copyright removed long ago.

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+ (possible exception with I key binding)
|
|
- 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+
|
|
- some tests under waftools/fragments/ might be GPLv2+
|
|
- version.sh is LGPLv2+
|
|
|
|
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".
