It is pretty much abandoned but did you try the dvd2concat perl script in the
tools directory?
It is supposed to work for this use case, but mplayer -dumpstream was tested
much more and is better suited if you need a file that contains a dvd track.
By trial-&-error I discovered that this:
'mplayer H:\VIDEO_TS\VTS_01_1.IFO -dumpstream -dumpfile TITLE1.VOB'
works. However, TITLE1.VOB does not play correctly.
TITLE1.VOB total time shown (1:06:28) [1] is slightly more than 1/2 the movie's actual total time
(2:11:15). Otherwise, playback is normal. Skipping forward and back in the video malfunctions.
[1] Curiously, PowerDVD reports TITLE1.VOB total time as 1:50:06.
Second-by-second, MPV playback progress bar at the 50% point:
Time (left) 01:04:30 [_________]__________ -00:01:36 Left (right)
01:04:29 [_________]__________ -00:01:35
01:04:28 [_________]__________ -00:01:34
00:00:00 [_________]__________ -01:06:28
00:00:01 [_________]__________ -01:06:27
00:00:02 [_________]__________ -01:06:26
At that point, skipping forward by '5' seconds jumps to the credits roll.
At that point, skipping back by '5' seconds jumps back to about 2 minutes prior
to the 50% point.
UPDATE
I just ran H:\VIDEO_TS\VTS_01_1.VOB ... H:\VIDEO_TS\VTS_01_6.VOB through MKVToolNix. I saved the
result as 'c:\AVOut\VTS_01_1..6.VOB.MKVToolNix.MKV'. It plays flawlessly in MPV.
What to conclude:
'mplayer H:\VIDEO_TS\VTS_01_1.IFO -dumpstream -dumpfile TITLE1.VOB'
doesn't fix the PTS problems that dog ffmpeg.
Merging & remuxing 'H:\VIDEO_TS\VTS_01_1.VOB' ... 'H:\VIDEO_TS\VTS_01_6.VOB' does fix the PTS
problems that dog ffmpeg.
I know this is not an MPlayer support mailing list, but maybe my experiences with MKVToolNix (works)
versus 'MPlayer -dumpstream' (doesn't work) can help the ffmpeg devs to determine why ffmpeg is
dogged by PTS problems that appear to be provoked by what I've been doing.
Warm Regards,
Mark.
