MPEG-FAQ 4.0:

Mpeg2ppm

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.

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.

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-licenced version is restricted to a local
           area netword (company) or a privat single host.

MPEG2PPM will  decode  a  (video-only)  MPEG-I-stream and
extract the rebuild frames as PPM-files (Portable Pixmap).
The  extracted  frames will be numbered starting from zero
(0), the first part of the filename is  derived  from  the
original MPEG-stream, the files extension will be .PPM.

The final PPM-files will be in 24-bit-format.

MPEG2PPM  expects  MPEG-1  video  streams only. It can not
handle multiplexed MPEG streams  or  video+audio  streams.
The  converter  uses  the  paris  entropy coding table set
(which I believe to be the MPEG-1 standard).
