I havnt tried cvs. 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. >>you are left with a standard which allows 18 combinations of samplerate >>and sample wordsize for 2-channel stereo audio (including 16-bit/44.1KHz >>RedBook, and going all the way up to 24-bit/192KHz), plus a range of >>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? 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. Dave.
