Summary0000960: DVD wizard fails to create DVD structure
DescriptionWhen creating DVD from a previously rendered vob file (PAL 4/3 VOB 2 pass), with a simple menu (single button), the DVD wizard stops before the creation of the iso file (see attached snapshot).

Some messages appear in the progress part of the dialog ... but get immediately cleared when the error occurs.
Additional InformationThe only clue for the moment is the console output:

libpng warning: Can't write tRNS with an alpha channel
libpng warning: Can't write tRNS with an alpha channel
libpng warning: Can't write tRNS with an alpha channel
QFile::at: Cannot set file position 0

I can't reproduce. Can you please give us more infos:

Which text was in the button, which font style and size did you use in the menu, did you set a background image or color, and which version of Qt do you have on your system?

Well, I did the simplest way as possible:
- added my vob file
- no chapter
- activated the check button to create a simple menu
- did not change anything in the menu settings:
  + kept the button text as is (i.e. "Lecture")
  + no background image

Qt: 4.5.0

In fact, it is not a UI thing. I followed the execution using a debugger and it is clearly dvdauthor invocation that resulted in an error.
Unfortunately, though the output of dvdauthor is captured in the error box of the wizard, this error box is immediately cleared at the end of the process and I cannot see the raised issue(s) ...
With the current behaviour, as the error box do not keep track of encountered errors, it is of little use.

I keep on investigating ...

I just committed a change in svn so that now the full log is visible in the DVD Wizard dialog, so please update if you can so we can get a better debug info

I manage to keep the files prepared by kdenlive prior to invoke dvdauthor, and then invoke dvdauthor in the console with these files: dvdauthor is crashing after tons of warnings

DVDAuthor::dvdauthor, version 0.6.14.
Build options: gnugetopt magick iconv freetype

Does it work if you try to create the dvd without menu? I am wondering if the problem might be with your source vob file...

Was it created with Kdenlive?

Same punishment without menu. By the way, I can confirm that I now benefit from error feedback I expected (DVD-Wizard-with-log.png). Thanks a lot !

The source vob file was created with Kdenlive.

Ok, then the problem is that the rendered file is not accepted. If you are using Kdenlive from svn, there were several fixes in the last days in MLT and Kdenlive, so I would recommend that you try to update and regenerate the vob file if possible.

The generated vob file was the source of the issue. Once re-generated with a fresh rebuild, everything goes right ...

As the wizard now displays what it is going on, the case can be closed :-)
