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,
mpeg_encode default.lparam

this produce output.mpg MPEG file.
