After looking at the mkisofs code in more detail, I've come to the conclusion that adding a new -dvd-audio option is the easier way to go. It also has the advantage of allowing mkisofs to do more specific sanity checks on the contents of the VIDEO_TS and AUDIO_TS directries. So I think the semantics should be: "-dvd-video" - sanity-check and sort/pad the VIDEO_TS directory "-dvd-audio" - sanity-check and sort/pad the AUDIO_TS directory "-dvd-video -dvd-audio" - sanity-check and sort/pad both directories. > If you like to work on it yourself, please send me a mail before you start. > I did limit the time I spend on cdrtools to get more time for creating > my OpenSolaris based UNIX distribution..... I've spent a short time this morning adding an initial -dvd-audio parameter to mkisofs. It extends the sorting function in udf.c to properly handle all the AUDIO_TS files, and replaces some (but not all) of the "if (dvd_video)" tests with "if (dvd_video || dvd_audio)". It's available here: http://dvd-audio.sourceforge.net/mkisofs-dvdaudio.diff That was the easy part. The harder (for me) part is to read the values of the absolute sector pointers in AUDIO_PP.IFO and add the appropriate amount of padding before that file (which is the first in the AUDIO_TS directory). Some time next week, I'll try to add a function to calculate the correct position of the AUDIO_PP.IFO file, but I'm not not I'll be able to manage to actually make mkisofs use that value when creating the image.
