Are there any good free C/C++ libraries that enable reading from common devices with filesystems such as UDF, and ISO9660 and extracting files/metadata etc.? So far all I've been able to find is [GNUs libcdio][1] which is promising, and some ["Magic UDF"][2] which has so many hits I'm disgusted, pushes other results in Google, and comes with a pretty extreme looking price tag. Cross-platform support is preferable (personal preference of course), and Windows compatibility is an unfortunate requirement. The less restrictive the license, the better, I have yet to investigate how compatible libcdio's GPLv3 license is.
