Multi-angle DVD and audio/video synchronization

[xaviour]

Spirited Away, PAL (region 2), Optimum Releasing Ltd.

MakeMKV produces a Matroska file with audio and video out of sync. For example, at
1:12:00 in the movie, the difference between audio and video is so large that the voice
of the characters is exchanged.

This DVD is multi-angle. The first angle is the animated movie itself while the second
angle is the story board. There are also 3 audio tracks (English 5.1, English 2.0 and
Japanese 5.1) and 1 subtitle track (English).

Other tools have problems dealing with the complex structure of this DVD. However it is possible to generate a proper
Matroska file. First of all, a full DVD backup has to be done using DVDFab. Only full disc copy works. The resulting ISO
file can be processed using regular Linux tools:

Code: Select all

mkdir -p iso
sudo mount -t iso9660 Spirited_Away.iso iso -o loop
tccat -i Spirited_Away.iso -T 1,-1,1 > Spirited_Away.vob
tcextract -t vob -x ps1 -a 0x20 < Spirited_Away.vob > Spirited_Away.ps1
subtitle2vobsub -p Spirited_Away.ps1 -i iso/video_ts/vts_01_0.ifo -o Spirited_Away
mkvmerge -o Spirited_Away.mkv --language "0:jpn" --forced-track "0:no" --display-dimensions "0:1024x576" --language "3:jpn" --forced-track "3:no" -a "3" -d "0" -S -T --no-global-tags --no-chapters Spirited_Away.vob --language "0:eng" --forced-track "0:no" -s "0" -D -A -T --no-global-tags --no-chapters Spirited_Away.idx --track-order "0:0,0:3,1:0" --attachment-mime-type "image/jpeg" --attachment-name "cover.jpg" --attach-file cover.jpg --title "Spirited Away" --global-tags Spirited_Away.xml
mkvalidator Spirited_Away.mkv

This eliminates the theory of a faulty DVD or a faulty drive.

Thank you for sharing the debug data. This disc indeed has a mastering error. The error would look like a very short glitch on majority of players, and will be ignored by around 10% of software - there are several ways to implement DVD cell navigation and only one will work properly with this disc. tccat is an example of tool that will work fine - not because tccat is good or bad, but because it uses a certain algorithm that ignores this particular mastering error. The next version of MakeMKV should process this disc fine.

The problem has been fixed in version 1.7.0.
