The mkisofs application needs to be adapted to correctly create a UDF disk image based on the sector pointers in the DVD-Audio IFO files.
I have written an initial patch against mkisofs which performs the correct sorting of the files when the -dvd-audio parameter is specified. If you apply that patch, you can create the UDF image as follows:
mkisofs -o image.iso -dvd-audio DVD/
The patch removes the need for a -sort file, but does not (currently) correctly position the files on the DVD according to the absolute sector pointers in the AUDIO_PP.IFO file.
A new patch against mkisofs bundles the -dvd-audio and -dvd-video options into a -dvd-hybrid switch.
A DVD-Audio player application needs to be written. There is a choice of two DVD-Audio player types - a player meeting the Audio Only Player (AOP) specification, or a player meeting the Video-Capable Audio Player (VCAP) specification.
An AOP player would only need to process the AUDIO_PP.IFO file and present a simple CD-Player like interface to the user. A fully-featured VCAP player would need to be an extension of an existing DVD-VIdeo player and would need to support a large subset of the DVD-Video specification, in addition to the full DVD-Audio specification.
