All relevant authors of the current code have agreed. As always, there are the usual historical artifacts that could be mentioned. For example, there used to be a large number of decoders by various authors who were not asked, but whose code was all 100% removed. (Mostly due to FFmpeg providing all codecs.) One point of contention is that Nick Kurshev might have refactored the old audio decoder code in 2001. Basically, there are hints that it might have been done by him, such as Arpi's commit message stating that the code was imported from MPlayerXP (Nick's fork), or all the files having his name in the "maintainer" field. On the other hand, the murky history of ad.h weakens this - it could be that Arpi started this work, and Nick took it (and possibly finished it). In any case, Nick could not be reached, so there is no agreement for LGPL relicensing from him. We're changing the license anyway, and assume that his change in itself is not copyrightable. He only moved code, and in addition used the equivalent video decoder framework (done by Arpi, who agreed) as template. For example, ad_functions_s was basically vd_functions_s, which the signature of the decode callback changed to the same as audio_decode(). ad_functions_s also had a comment that said it interfaces with "video decoder drivers" (I'm fixing this comment in this commit). I verified that no additional code was added that is copyright-relevant, still in today's code, and not copied from the existing code at the time (either from the previous audio decoder code or the video framework code). What apparently matters here is that none of the old code was not written by Nick, and the authors of the old code have given his agreement, and (probably) that Nick didn't add actual new code (none that would have survived), that was not trivially based on the old one (i.e. no new copyrightable "work"). A copyright expert told me that this kind of change can be considered not relevant for copyright, so here we go. Rewriting this would end with the same code anyway, and the naming conventions can't be copyrighted.

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+.
