as I said in other e-mail, you are right: even the kernel
has plenty of files with no copyright
but there is a misunderstanding here
the reason why Debian ftp-installer rejected mplayer is that: I
have read all the files in mplayer, and AFAICT there are
files in mplayer which have a license that is not GPL: see list at bottom

so this is good, we can get rid of this file.
so please if you developers have time, tell me how we can fix things
with these other files (note that: files in point 1 are the most
important to be fixed; files in point 2 3 may be probably left as they
are, I just need someone to confirm me on their GPL origin;
for the files in 4, read below)
----- here is the list of all the files in mplayer that do not have
an explicit GPL or LGPL statement
1) The following files have a license:
libavcodec/jfdctint.c
same license as libjpeg62 (which should be shipped with the
code, and it is not)
libavcodec/armv4l/jrevdct_arm.S
generic "no liability/as is" license
libavcodec/fdctref.c
generic "no liability/as is" license,
Copyright (C) 1996, MPEG Software Simulation Group. All Rights
Reserved.
[PROBLEM FIXED: we delete the file from tarball for Debian]
libvo/vo_pgm.c
libvo/vo_md5.c
probably the same as libavcodec/fdctref.c (same copyright MPEG...)
libvo/vo_sdl.c
undecided, but it seems that it was GPL in the past
libmpcodecs/native/xa_gsm.c
generic "no liability/as is" license,
libdha/pci.c
libdha/sysdep/libdha_os2.c
generic "no liability/as is" license (from XConsortium code base?)
mp3lib/*
refers to nonexistent README; moreover the code seems to be
taken from mpglib in mpg123, which is not GPL.
libmpdemux/genres.h
Copyright (C) 2001 Jason Carter
refers to an unavailable LICENSE; it only contains the list of genres
2) In the following files there is an explicit copyright statement, but no
license: for some files I could track down a GPL or LGPL origin:
libvo/vo_mpegpes.c
same as ffmpeg
libvo/vo_dxr3.c
was part of ffmpeg, see
http://mplayerhq.hu/pipermail/mplayer-cvslog/2001-November/003377.html
drivers/video/radeonfb.c
framebuffer driver for ATI Radeon chipset video boards,
probably from linux kernel code; drivers/radeon/radeon_vid.c is GPL
linux/lrmi.c
seems to be taken from http://cvs.debian.org/lrmi/
loader/*.c
loader/module.c
loader/pe_image.c
loader/pe_resource.c
loader/elfdll.c
loader/wine/*
loader/qtx/debug/module.c
from wine ?
3) This I think we may consider GPL, since they are part of the mplayer
code, and were written by mplayer's authors
libvo/vo_dga.c
loader/dshow/DS_AudioDecoder.c
4) these are the files remaining:
TOOLS/benchmark-gab/README
Author: gabucino
License: for exclusive usage with MPlayer (wonder;)
[I understand that this is intended as a pun; but the
phrase "for exclusive usage" is against the Debian Freesoftware
guideline; so I wish that gabucino may not mind changing the
License statement]
TOOLS/mpfc/mpfc-kr.c
TOOLS/mpfc/mpfc-ce.c
Author: Sunjin Yang <lethean at realtime.ssu.ac.kr>
just says that it was created for mplayer
a.
