Fetch Preview-Image failed due to COMMA instead of a DOT used in a command-option

Hey Guys,

well, I've been bussy with this for a while.

The following command is issued on machine 1:

The following command is issued on machine 2:

The command finishes succesfully on machine 2, unfortunately not on
machine 1. I found kind of a small difference ....

machine 1: -ss '0,280'
machine 2: -ss '0.280'

On machine 1 dvdrip uses an COMMA. On machine 2 dvdrip insert a DOT.
If I execute the command on machine 1 manually with a DOT instead of a
COMMA, the command finishes nicely.

Well, .... actually I don't know what to do .... Is this a perl issue ?

Greetings,

Nico

More or less ;) The program uses sprintf() here to round the time value
of the -ss option. And depending on your locale settings a comma is used
instead of the dot to mark the decimals.

You can fix that by either use the same locale settings on machine 1 as
on machine 2, or change lib/Video/DVDRip/Title.pm this way:

In line 3138 you find

my $start = sprintf("%.3f", $start_frame / $frame_rate);

add this line after it:

$start =~ s/,/./;

This should work.

Jörn
