>From the man page:

-stream-media-size #
       Select streaming operation and set the media size to #  sectors.
       This  allows  you  to  pipe  the  output of the tar program into
       mkisofs and to create a ISO-9660 filesystem without the need  of
       an intermediate tar archive file.  If this option has been spec-
       ified, mkisofs reads from stdin and creates a file with the name
       STREAM.IMG.

Also:

-split-output
       Split the output image into several files of approximately 1 GB.
       This helps to create DVD sized ISO-9660 images on operating sys-
       tems without large file support.

NetBSD has large file support, so there is no need to do this.

     As this is not part of NetBSD, this is not an appropriate question
for this list.  It would be barely appropriate for pkgsrc-users@ as it
is probably about a package.  However questions about using a package
generally belong on a list dedicated to the package in question.

     This is expected.  See the manpage snippet above that says when
you use the -stream-media-size option it expects the data to be
presented on standard input.
