PROGRAM:
NAME
atisplit - conversion utility from the GATOS package.
SYNOPSIS
atisplit
DESCRIPTION
The program atisplit is a small utility to convert gatos capture file
(gatos.yuv) into a series of yuv frames good for input to mpeg_encode
program.
mpeg_encode can be obtained on metalab (http://www.metalab.unc.edu/).
note that since mpeg_encode uses yuv files with only quarter of cb and
cr fields the output files have less information than the input one. in
particular the total size of the output files should be just below 3/4
of the size of the input file.
USAGE
- Start the "TV in a Window" application:
./xatitv &
and capture whatever you want,
atisplit
atisplit furiously prints out frames.
- You must edit the default.lparam file (see below);
- And,

this produce output.mpg MPEG file.
