/*
* udf.c - UDF support for mkisofs
*
* Written by Ben Rudiak-Gould (2001).

/*@@C@@*/
/*
* Some remaining issues:
*
* - The following functions create directory entries with 2 or
* more AllocationDescriptors:
*
* set_file_entry()
* set_macvolume_filed_entry()
* set_attr_file_entry()
* set_filed_entry()
*
* To support files > 236 GB, we need to be able to deal with a list
* of direcoty entries that span more than one sector.
*
* - The link count may be wrong if -hide-udf is used.
*
* - Do not forget to edit joliet.c and remove the VIDEO_TS lines after
* we did implement a decent own file name handling for UDF.
*
* - There's no support for hard links. This could be easily fixed since
* the correct harlink support is available.
*
* - The file system mirrors the Joliet file system, so files excluded
* from Joliet will also be excluded from UDF, the -jcharset option
* also applies to UDF, file names too long for Joliet will also be
* truncated on UDF, and characters not allowed by Joliet will also
* be translated on UDF. (Fortunately, Joliet is pretty lenient.)
*
* - convert_to_unicode is always called with in_nls, not hfs_nls. This
* may lead to incorrect name conversion sometimes when using a Mac
* filesystem. See joliet.c for an example of what's supposed to be
* done.
*
* - DVD-Video discs are supposed to have Copyright Management Information
* in both the ISO and UDF filesystems. This is not implemented in ISO,
* and the code to do it in UDF is currently #ifdef'd out. I'm not sure
* whether discs without this information are actually DVD-Video
* compliant. The Copyright Management Information is described in ECMA
* Technical Report TR/71.
*
* - Most of the space before sector 256 on the disc (~480K) is wasted,
* because UDF Bridge requires a pointer block at sector 256. ISO 9660
* structures could be moved below sector 256 if they're small enough, but
* this would be ugly to implement since it breaks the output_fragment
* abstraction.
*
* - Each file must have a File Entry, and each File Entry seems to
* require its own 2K sector. As a result, there is an overhead of more
* than 2K *per file* when using UDF. I couldn't see any way to avoid
* this.
*
* - Read performance would probably be improved by placing the File Entry
* for each file just before the file itself, instead of at the beginning
* of the disc. But this would not work for DVD-Video files, which have
* to be stored contiguously. So there would have to be an override
* mechanism to handle this case. I don't know if it's worth the trouble.

* JACKET_P files are still images (single frame mpeg video .i.e mp2
