We try to make up a DVD-Video disc on Linux. DVD-Video disc contains a UDF/ISO9660 filesystem, and every file in it should occupy the right sectors. I know that mkisofs can do this, but we want to record video on-the-fly.
The only way to solve this is to dump live video stream from logical block address which is large enough to accomodate file system and DVD-Video structures and generate both file system and DVD-Video structures to "cover" the live recording in compatible way *afterwards*, i.e. after you know how large is live video recording actually was.
mkisofs doesn't support this functionality. Therefore we would like to use UDF filesystem and udftools to do this. Can I use them to make up a DVD with a UDF/ISO9660 filesystem and every file in it occupies specified sectors?
Kernel UDF is incapable of producing DVD-Video compatible layout. It was never design goal. A.
