_M_p_e_g_2_p_p_m 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.
--hh This option will show the usage.
--ff This option will extract only the first frame
of the MPEG-stream. The PPM-file will be
named after the MPEG-stream-file, its exten-
sion will be .PPM.
--ss ssttaarrtt This option let you specify a starting frame.
Converting will start with the specified fra-
menumber. Has to be used in conjunction with
the following option.
--ee eenndd This option let you specify the ending frame.
Converting will stop with the specified fra-
menumber. Has to be used in conjunction with
the option above.

You could start _m_p_e_g_2_p_p_m with f.e. the following options:
mpeg2ppm -h
mpeg2ppm -f < ifa.mpg
mpeg2ppm -s 10 -e 20 ifa.mpg

_M_p_e_g_2_p_p_m 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).
Some streams do not end with the proper sequence end code
and will probably generate an "Improper sequence end
code." error when done playing.
