Keeps things > Unixy. ;-) libscg: I can't find it using "apt-cache search", and I think that it is used only internally by cdrecord. cdrecord 2.x is licensed under CDDL, so I think I can't copy the library into my GPLed software. libdvdread: you may be right that it is only for video DVDs, I have just checked short description of package. libdi: I can't find it in Debian repository, but I will look into it closer later. cdrtools: in theory it might/may be possible to read content of CD/DVD with one of programs from cdrtools package, i.e. burn DVD disc and then verify it with by reading disc with cdrtools, but I can't assume that cdrtools is installed on user's system, next to growisofs. Sometimes a library is more convenient than a separate program :) growisofs: grepping the source shows that growisofs has "-use-the-force-luke=wrvfy for WRITE AND VERIFY(10)" option. I don't know yet how it works, but it may be worth checking. I'll wait and see. There are some possibilities to check and explore. Kind regards, Kamil |
