Hi, > I'd have to considerably ramp up my knowledge on those, as it is currently > nil...
I have a note sheet with pointers into ECMA-167 and UDF-2.60 and lots of question marks. (Plus a copy of the interesting stair shaped ASCII painting at the beginning of libcdio's udf_fs.c) If you happen to need a description of UDF, then we have a common interest and should cooperate on collecting facts. (E.g. i only have UDFs from mkisofs and from the Linux kernel. The specs leave enough room for surprises in examples from other producers.) > Have you had a look at what 7-zip source does (7z/CPP/7zip/Archive/Udf/)? That would be a source of information for the description. Google found me https://bitbucket.org/gongminmin/klayge/src/606b64ac900a/External/7z/CPP/7zip/Archive/Udf ... ahum ... the stair painting seems to fit into UdfIn.cpp enum EDescriptorType. (Riddling about libcdio "Root Dir File Entry" and "File data", though.) C++ is hard to decode for me. Well, if nothing else helps, one will have to determine what this code does and how it relates to the specs. First one should explore (exploit ?) the libcdio code, of course. Linux kernel code and docs could be interesting too. >From such a description it would be quite straightforward to fix problems in libcdio or to implement own UDF software. Have a nice day :) Thomas
