This has a messy history all back to the initial commit with multiple refactors, but it seems almost all authors agreed. Exceptions:2aa6acd974: patch by someone who could not be reached. Whether or not this code is still in mpv is unknown, but the affected code was moved to stream.c at one point anyway.3859bbd9fe: not sure if this is a patch by the mentioned person (I assume not) or the committer (who agreed to LGPL), but it seems the change is too trivial to affect copyright. It seems even the FD check can be dropped, which I'm doing in this commit.58846451f0: author doesn't reply. But reverting this and letting someone who has never seen this commit before redo it would lead to exactly the same code. So I'm claiming that the change is not copyrightable.

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".
|
|
|
|
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.
