=========================================================================
This is the MPEG to PPM converter running under DOS. Its based
on the MPEG-decoder called "mpeg_play" by the Berkeley Research
Group. The basic idea was coming from the PPM-patch by Jef
Poskanzer. Many thanks to both.
It was compiled with Gnu's DOS-port of their GCC-compiler,
called DJGCC Version 2.4.1 and NDMAKE Version 4.5. So please
read the GNU-License-file 'LICENSE.GNU'.
The DOS executable in this distribution is named MPEG2PPM.EXE
and there is a batch-file called MPEG2PPM.BAT for those that
are not familiar with the DJGCC-package. The final extracted
PPM-files can be displayed or converted with f.e. DISP160.ZIP.
They are in 24-bit-format.
If you want to know more about MPEG, read the file MPCDINFO.TXT !
SHAREWARE
---------
MPEG2PPM is inexpensive shareware. If you are continuing using
it after a 30 day trial-period, please send a letter containing
the filled and signed registration-form and the little donation
of 10 $ or 15 DM in cash to the adress below.
The you will receive a PASSWORD enabling you to encrypt the
full-licensed version shipped in the archive FULLMPEG.ZIP using
the command 'pkunzip -spassword fullmpeg.zip'. This will
overwrite the shareware version of MPEG2PPM.
ATTENTION: The dots the shareware version of MPEG2PPM produces
are just delay, to force you to register.
ATTENTION: A registration is recommended for commercial use.
ATTENTION: The full-licensed version is restricted to a local
area netword (company) or a privat single host.
Please keep me up to date with everything thats new about MPEG
by sending new source-code, utils, documents concerning MPEG-I
or MPEG-II to the e-mail-adress below.
NEEDS
-----
Version 1.2 of MPEG2PPM is compiled with a version of DJGCC that
allows the executable to running under DPMI (so even in
a Windows-DOS-Box), but still needs at least a 386-machine.
The Gnu-environment-executable 'GO32.EXE' has to be somewhere
in the PATH. If running on a 386, the GNU-387-emulationfile
'EMU387' has to be, where the environment variable GO32 is
pointing to, so if the emu-file is in D:\LIB enter:
set GO32=emu d:/lib/emu387
and then just start the program by typing
MPEG2PPM ifa.mpg
CHANGES
-------
Please do not recommend any big changes or any new versions
of this program. Its working all right, doing its job and
there is really NO need in enhancing it. But, if it should
not work on any DOS-system, please report it with a complete
description to the e-mail-adress below.
