Nice to see that someone did start something like this. > Looking at the source for mkisofs, there appears to be some initial > support for DVD-Audio (i.e. correctly sorting the files in the AUDIO_TS > directory), but this appears to be incomplete (it doesn't take account > of all the AUDIO_TS files such as AUDIO_PP.IFO or AUDIO_SV.IFO) and also > only works when the -dvd-video option is enabled. Correct. > The main problem is that -dvd-video fails with an error when the > VIDEO_TS directory is empty (as is the case on a pure DVD-Audio disc). > > The UDF requirements for DVD-Audio appear to be very similar to those > for DVD-Video The various IFO files in the AUDIO_TS directory > contain both relative and absolute sector pointers which need to > correspond with the output of mkisofs if the DVD-Audio is to be playable > on hardware players. > > I've described the UDF requirements in more detail, along with example > "isoinfo -l" outputs at http://dvd-audio.sourceforge.net/spec/udf.shtml > > My proposal would be to extend the -dvd-video option to properly deal > with the contents of the AUDIO_TS directory, and also deal with the case > of the VIDEO_TS directory being empty. > > The DVD-Audio and DVD-Video specifications are very closely linked, and > the specs allow a so-called "Univeral" DVD-A/V disc that contains linked > AUDIO_TS and VIDEO_TS "zones". So even though the name -dvd-video isn't > appropriate, I think it would be cleaner to handle both DVD-A and DVD-V > via a single option, rather than adding a seperate -dvd-audio option.

I did limit the time I spend on cdrtools to get more time for creating my OpenSolaris based UNIX distribution.....
