Running vlc /path/to/dvd-video.iso, I'm getting:

[0x8787ccc] main decoder error: no suitable decoder module for fourcc `undf'. VLC probably does not support this sound or video format.

notes:

  • The version of vlc is 1.1.3.
  • The DVD plays well when not in iso format (when it's normal files on the filesystem).

    Does the path contain non standard characters? And what do you mean by 'extract'? Do you mean that you mount the iso file and read the contents directly? – asoundmove Feb 2 '11 at 14:16
  • @asoundmove The path contains normal characters; I updated the answer. – Tshepang Feb 2 '11 at 14:16
  • ubuntuforums.org/archive/index.php/t-512698.html shows a similar discussion to the one you've started here. Maybe that will help? – asoundmove Feb 2 '11 at 14:16
  • update: this works on a fresh Debian install (right-click, select VLC, and voila!) ; I don't know what the fix is – Tshepang Feb 2 '11 at 14:31
  • This question is not applicable to the more recent VLC versions that can play ISO-s directly. – user32012 Sep 22 '16 at 14:07

Mount it as a loopback first.

mount -o loop,ro -t iso9660 /path/to/file.iso /path/to/mountpoint/

Or try this...

vlc dvd://path/to/iso
  • That is not directly, unless you are suggesting a workaround? – Tshepang Jan 9 '11 at 22:01

    I could be wrong, but I'll bet the second option is about as directly as you will find. – Steven D Jan 9 '11 at 23:17
  • Nah, 2nd option doesn't work. It expects a normal file system: libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed. – Tshepang Jan 11 '11 at 13:36

    Why is it that you are opposed to mounting it? – bahamat Jan 12 '11 at 6:16
  • It's extra work. – Tshepang Jan 29 '11 at 9:20

As this is an old question, it may be useful to say that more recent VLC (2.1 and later) versions should be able to play ISO-s directly, unless there is something wrong with the iso.

Do you have to use vlc? mplayer can usually work out a video dvd iso (or even a partial incomplete iso) contains mpeg streams well enough to play them without loopback mounting or complicated flags. Doing it this way means menus, subtitles, alternate soundtracks are unlikely to work tho.

mplayer /path/to/dvd.iso

    Does MPlayer even support menus? – Tshepang Feb 2 '11 at 14:25
  • You can watch the mpeg stream behind animated menus but the hotspots aren't connected up to anything useful. – user4410 Feb 6 '11 at 13:43
