Detailed Description

Thin c++ wrapper around mpeg_encode/ppmtompeg.

The implementation opens a pipe to an mpeg_encode or ppmtompeg subprocess, using the "INPUT_DIR stdin" configuration option, and sends frames over the pipe to be encoded into the resulting mpeg file.

Ucb stands for "University of California-Berkeley", where mpeg_encode was originally written.
