            Bug ID: 383011
           Summary: k3b cannot create DVD video image
           Product: k3b
           Version: 17.04.3
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Video DVD
          Assignee: k3b at kde.org
          Reporter: erwinl at dds.nl
                CC: michalm at jabster.pl, trueg at kde.org
  Target Milestone: ---

The following is a copy from
"https://bugzilla.opensuse.org/show_bug.cgi?id=1051338".

When trying to create a video DVD image, k3b issues the following error
messages:

    The project does not contain all necessary video DVD files.
    The resulting DVD will most likely not be playable on a Hifi DVD player.
    Could not determine size of resulting image file.

Note that this happens with the original k3b version coming with Leap 42.3, the
packman version, as well as the version from KDE Applications.

Reproducible: Always

Steps to Reproduce:
1. Select a directory that contains all necessary files for a DVD video.
2. Start k3b and tell it to only create an image from these files.

It doesn'matter which video directories you choose, it happens with all of
them.

Actual Results:  
The following is the debugging information produced by k3b:

I tried to use strace to see what happened. This is what I found:

"k3bVideoDvdyTjqwI/k3bVideoDvdyTjqwI/VIDEO_TS/VTS_01_5.VOB") = 0

Apparently, k3b creates directory
"k3bVideoDvdyTjqwI/k3bVideoDvdyTjqwI/VIDEO_TS" and in this directory symlinks
are created to the real video files.

I created these directories and the symlinks manually to see what happened with
the genisoimage command (mkisofs is just a symlink to genisoimage):

erwin at frodo:~> ls -l k3bVideoDvdyTjqwI/k3bVideoDvdyTjqwI/VIDEO_TS/

lrwxrwxrwx 1 erwin users 31 29 jul 10:39 VTS_01_5.VOB ->
/home/erwin/ZZZZZZ/VTS_01_5.VOB

If I run the genisoimage command as follows (some unnecessary parameters have
been removed for clarity)

/usr/bin/genisoimage -udf -iso-level 1 -verbose -dvd-video -o /tmp/k3b.iso -f
k3bVideoDvdyTjqwI

it results in the following error

Warning: -follow-links does not always work correctly; be careful.
I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage 1.1.11 (Linux)
Scanning k3bVideoDvdyTjqwI

/usr/bin/genisoimage: Could not find correct 'VIDEO_TS' directory.
/usr/bin/genisoimage: Unable to make a DVD-Video image.
Possible reasons:
  - VIDEO_TS subdirectory was not found on specified location
  - VIDEO_TS has invalid contents

Thus, with this command, genisoimage cannot find the VIDEO_TS directory.

However, with the following genisoimage command (note the difference in the
input directory)

/usr/bin/genisoimage -udf -iso-level 1 -verbose -dvd-video -o /tmp/k3b.iso -f
k3bVideoDvdyTjqwI/k3bVideoDvdyTjqwI

an image is created as expected.

It seems that either k3b creates an incorrect directory structure,
"k3bVideoDvdyTjqwI/k3bVideoDvdyTjqwI/VIDEO_TS/" in stead of
"k3bVideoDvdyTjqwI/VIDEO_TS/", or it is giving incorrect directory information
to genisoimage.
