Strange behaviour when writing metadata to images

Hello,

I am running DK 4.0.0 on openSUSE 13.1.
I am encountering some very strange behavior when writing metadata to
images:

1. All my images contain GPS-information; this information gets
displayed in the EXIF sidebar for some of the images, for others not,
although I can see the GPS-information. when clicking on image ->
Geolocation.

2. When writing exif information to the image (jpgs), frequently - but
not always - it happens that the image gets completely deleted from the
directory. This is true only when in the "Reading and Writing Metadata"
settings "Write to image and xmp sidecar" is activated. When writing
only to the xmp-sidecar images stay there. This means images get deleted
when writing new Exif-data into the image. This is most annoying if you
don't have a backup of your images.

I am using the DK version that is being distributed together with
openSUSE 13.1; but I also saw this behavior on a version that I compiled
myself.
Has anybody any clue what is wrong?

Rotate a movie?

I shot a short video (mp4) with a new smartphone held vertically, and it
appears in Digikam (3.5.0) horizontally (that is, the bottom of the
video is at the right side of the screen, etc.). I can rotate the
thumbnail 90d clockwise, but not the video itself. Any help?

Hi
You should use video editor, like Avidemux, the best (for me)

I just found out that obviously a program with the name "rygel", which is a UPNP/DLNA server running under Linux, is causing the problem. It looks like rygel somehow interferes with DK. When I kill rygel on my system, DK does no longer delete images after writing exif-data into the image. Has anybody an explanation for this strange interference?

a) see here http://mail.kde.org/pipermail/digikam-users/2014-May/019205.html

b) I have Rygel running, too, saving freshly tagged images only works with .xmp sidecar-files. Stopping Rygel makes DK function as usual: Tagging works flawlessly with or without sidecars.

Thanks a lot for your post, I had assumed I was the only one with this problem. Would this be sth for the Rygel buglist?

Arne

Thank you, Maderios. I installed Avidemux from the Kubuntu repository
and it has many functions, but I do not see how to use it to rotate that
movie.

load the video, select an out format, then select filters, transform, rotate

Hi Maderios, since you use KDE, you may like to give a try to KDEnlive.
That is the video editor I use on KDE. If you are familiar with Adobe
Premiere, this is quite similar. Among the clip effects you will find
the tool you are looking for.

See this upstream report here :

https://bugs.kde.org/show_bug.cgi?id=333565

To resume : if Rygel program is run in background when digiKam DB
opened, this one will be locked and digiKam will only access to DB in
read only mode.

In other word, move Rygel program to the trash and let digiKam work properly...

Re: Strange behaviour when writing metadata to images

"In other word, move Rygel program to the trash and let digiKam work properly..."

That's what I did already ! I am now using minidlna as a UPNP-server instead of Rygel. With minidlna there is no interference problem with DK !

Hi
I gave a try to KDEnlive and many other video editors, many, many times.
The only one that really works is Avidemux.

kdenlive works very well these days, but it's overkill for rotating small video

Or you can use either ffmpeg or mencoder; both can be used
from CLI on a single file, or in a script such as:

#!/bin/bash
#* 0 Rotate by 90 degrees clockwise and flip (default).
#* 1 Rotate by 90 degrees clockwise.
#* 2 Rotate by 90 degrees counterclockwise.
#* 3 Rotate by 90 degrees counterclockwise and flip.

#
for i in *.avi
do
mencoder -oac copy -ovc lavc -lavcopts vcodec=mjpeg \
-vf rotate=1 $i -o $i.avi;
done;

Read the man pages for your favourite format. It could be this:

ffmpeg -i input.mp4 -vf vflip output.mp4

There are gazillions of ways to do this,
google/duckduckgo/etc is your friend...
