яко се озорих - не успях да намеря dvd-audio с празно VIDEO_TS. в крайна сметка смъкнах некво, което има 4 titles, с по 1 chapter. ето така стана рипване към wav:

vlc "dvdread:///mnt/tmp@1:1-1:1" --play-and-stop --sout="#transcode{acodec=fl32,ab=256}:std{access=file,mux=wav,dst=./dvd-1.wav}"



vlc "dvdread:///mnt/tmp@2:1-2:1" --play-and-stop --sout="#transcode{acodec=fl32,ab=256}:std{access=file,mux=wav,dst=./dvd-2.wav}"



vlc "dvdread:///mnt/tmp@3:1-3:1" --play-and-stop --sout="#transcode{acodec=fl32,ab=256}:std{access=file,mux=wav,dst=./dvd-3.wav}"



vlc "dvdread:///mnt/tmp@4:1-4:1" --play-and-stop --sout="#transcode{acodec=fl32,ab=256}:std{access=file,mux=wav,dst=./dvd-4.wav}"
