I have a DVDISO file, and opening it doesn’t work because my built-in disk mounter can’t read it.
So, I open it up with VLC and all looks fine. When booting it up it’s supposed to take you to a screen where you can select what clip you want to see. Remember this as the selection screen, and it has 3 clips and a PLAY ALL button. The first clip works… Partially. If you skip too far, VLC kicks you back to the selection screen. The 2nd and 3rd clips do not work and kick you back on sight.
Cracking it Open
So, I get some software to open & extract the ISO’s files and the first thing it tells me is that a few
IFO files are corrupted, and a
VOB file as well. Everything comes out and I don’t really know how to work with
VOB file seems a little corrupted so I ran it through
ffmpeg -i './VTS_01_1.VOB' -c copy './PARTLYBADBUTFIXED.VOB' So it does not break while in VLC.
To clip the never corrupted vob:
ffmpeg -t 00:13:13 -i 'NEVERCORRUPTED.VOB' 'WHATIWANTPART1.VOB'
To clip part of the corrupted vob:
ffmpeg -ss 00:13:13 -i 'PARTLYBADBUTFIXED.VOB' 'WHATIWANTPART2.VOB'
Long story short: I then tried to create a new
VOB by getting a uncorrupted clip, and clipping a unique part of the ‘fixed’ file which luckily wasn’t broken, and concated it as such:
ffmpeg -i 'concat:uncorrupted.vob|fixed.vob' -codec copy fixed.vob
I’m not really sure if this file would work if I decided to plug it back in, which I haven’t started yet but the filesize is extremely questionable. The og VOB was 1.07~ GB, and my fixed/edited VOB is 667 MB. Any suggestions?
ffmpeg probably wasn’t the correct software to use, due to some of the buffer underflow errors & ‘incorrect’ timestamps.
The VOB itself is supposed to be
16:41 in length, but VLC reads it as 3:41. Playing it, it clearly shows me that it has all clips but the timing is really screwed up. This is my first time ever working with .VOB, .BUP, and .IFO files.
Edited VOB by me:

OG, But after I tried my best with ffmpeg to fix it:

So, is there something that will help me edit/look at BUP,IFO,VOB files better?
