Hi,
I've recently started the process of attempting to document the
DVD-Audio standard and to write some useful free software tools for
authoring and playback of DVD-Audio disks.
For both technical (i.e. it's hard) and legal (i.e. it's illegal in many
countries), I'm not attempting to deal with either the copy prevention
technologies or Meridian Lossless Packing, so my project will never be
able to play back commercial DVDs.
The aim is to write an authoring application capablle of creating
DVD-Audio disks compliant with hardware DVD-Audio players, and also to
write an open source DVD-Audio player that supports the playback of
unencrypted DVD-Audio disks with uncompressed LPCM audio tracks.
Currently, the project is in the very early stages - I'm in the progress
of adding my notes to the project website, and have started to write
some software. The home page is here:
http;//dvd-audio.sourceforge.net/
There is a dvd-audio-devel mailing list that all are welcome to join.
Regards,
Dave.

hi Dave
by coincidence, an unencrypted dvda just landed on my hard drive. Do
i assume correctly that there are no aob demuxers available? Mplayer
seems to have some support, but on 1.0pre6 it detects this file as
stereo 96k with a wordlength of 0bits. I havnt tried cvs.

6-channel uncompressed surround sound formats.
so just out of interest, are current players too useless to play wav files,
or are you looking for some other additional feature of the aob format?
cheers

Yes, it's not possible to "author" a DVD containing WAV files. But that
I mean control the order the WAVs are played back in, decide if there
should or should not be gaps between tracks, offer alternative playlists
for the same content etc etc.

I have more or less nailed the format of an AOB - it is similar enough
to a VOB for mplayer to recognise it (both are MPEG Program Streams with
LPCM audio stored as a private stream). But an LPCM private stream in
an AOB file is not the same as the one in a VOB - the LPCM headers are
different.
AFAIK, there are no AOB demuxers available at the moment, but I'm
planning to write one. Keep an eye on my project at
http://dvd-audio.sourceforge.net I've already partially document the
contents of the AUDIO_TS directory.
