[Libcdio-devel] private udf information

[Shaya Potter]

in libcdio a bunch of information is kept private and not readily 
available to programs, what I'm concerned about is basically the 
start/length of a file.

this is in the udf_dirent_t structure, but is hidden from programmers.

I care about this as I am trying to write a barebones dvd decrypter that 
works on images files

i.e. I have some DVDs in bad shape, so using 1) lsdvd to authenticate 
the disk, 2) ddrescue to recover a complete image, but it still has CSS 
embedded, so then need to remove the CSS, but I have to basically check 
if I need to rekey on each VOB file and need to know the start of it to 
rekey on the right block.  libcdio's udf support should provide it to 
me, but as it's hidden, it doesn't.

any thoughts on providing an interface to this data?

thanks
