mkisofs needs to have a file system to scan to produce an output image.

If you were to alter mkisofs to accept one file from a pipe, then you
would have to know how long the input stream is going to be beforehand
(although, thinking off the top of my head, if you are creating an ISO9660
image with just one input file, it would be possible to put the directory
info at a known place at the end of the CD which contains the start extent
and length of the stream after it's been written ...)

There is quite a lot of documentation included with the mkisofs source code -
including the source itself ... although understanding the code is not 
what I would describe as easy ...

There are also a number of links via:

that may help - I guess the documents on ISO9660, Rock Ridge and Joliet
may be a useful starting point.
