wm4 a550731209 Copyright, LICENSE: switch to GPL version 2 or later
Now that talloc has been removed, the license can be switched back to
GPLv2+. Actually, there never was a GPLv2+ licensed MPlayer (fork or
not) until now, but removal of some GPLv2-only code makes this possible
now. Rewrite the Copyright file to explain the reasons for the licenses
MPlayer and forks use. The old Copyright file didn't contain anything
interesting anymore, and all information it contained is available at
other places in the source tree.

The reason for the license change itself is that it should improve
interoperability with differently licensed code in general.

This essentially reverts commit 1752808.

Plaintext

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+, 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. Files without Copyright notice are licensed as LGPLv2+.
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.
