NAME

mpeg2ppm - MPEG to PPM converter

SYNOPSIS

mpeg2ppm [-h] [-f] [filename]

DESCRIPTION

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.

-h: This option will show the usage.

-f: This option will extract only the first frame of the MPEG-stream. The PPM-file will be named after the MPEG-stream-file, its extension will be .PPM.

NOTES

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).

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