Hello,

Since the upgrade to xenial, when I open a picture from Gwenview, the picture open but with more error windows with the following message.

The URL can not be listed audiocd: / device = / dev / sr0?

I close the error windows and then I can continue to view the images without problems.

When I start gwenview in konsole, I get this warning (three times):

Code: Select all
WARNING: Phonon::createPath: Cannot connect  Phonon::MediaObject ( no objectName ) to  Phonon::AudioOutput ( no objectName ).


I do not understand what phonon has to do with gwenview.

Thank you for any suggestions leading to the elimination of error windows.

Gwenview can be used to view videos by way of Phonon, this is not a new functionality

question does Kaffeine and/or Dragon Player play videos ok?

I would guess a packaging issue

try:
- reinstalling
- switching Phonon backends

I have removed gwenview, clean the cache (package) and reinstalled gwenview. The problem is still present.
For phonon, how to change the backend?

There are 2 available Phonon backends, Gstreamer and VLC though you may only have one installed

systemsettings -> Multimedia -> Audio and Video -> Backend

I looked at the Gwenview rc files and see nothing related to video or Phonon

I have only one engine (gstreamer). But I would be surprised that a problem with the backend choice. Otherwise, several other KDE users would have already complained.

Here is the complete message received in konsole when I start an argument with gwenview image. The first lines about icons are also present when I start dolphin in konsole mode.

The two lines "WARNING: ..." correspond to popup windows error message. I noticed that closing the error window, the gwenview tree (right of the screen window) was changed. This is a further indication.

Code: Select all

It may not be the backend but when there's an issue no one else is reporting then you try difference things hoping something helps.

If you open a jpg in Dolphin into Gwenview does the error appear?

Does a new user experience it?

Yes, that is my usual way to open an image.

In the list of applications on "open with" image opens normally without error. Only with gwenview I get errors when opening an image. By performing manipulations in gwenview, I realized that the error occurs whenever I click once on a folder in the tree. Once visited folder, the error no longer occurs if I return to the directory.

no idea as I've never seen or heard of this all I can suggest to try all possibilities to try and focus in on a possible cause.

if you open the file from within Gwenview? or as another user?

do non jpg files (png, gif, tif) do same ?

try reinstall the gstreamer packages

again see what happens if you change backends

Ok. It's really weird. In my setup, I see that Kubuntu use Phono GStreamer (4.8.2). But I have no package named GStreamer or gstreamer. I use the command "dpkg-query -l gstreamer" to query the list of installed packages. Similarly, there is no GStreamer package (or gstreamer) in deposits. So how to remove and reinstall gstreamer?

I should also say that in selecting the tab "News" or "Actions", gwenview opens without error. The error therefore only occurs when the application opens with the "Directory" tab.

I don't do *buntus but I would have though gstreamer was installed by default, note there is no gstreamer.deb but a bunch of gstreamer*.deb

again don't do *buntus nor apt but maybe
Code: Select all
 sudo apt-get --reinstall install gstreamer*
or use the package manager to do the reinstalls

this is a list of gstreamer packages http://packages.ubuntu.com/search?keywo ... ection=all

what's the tab "News" or "Actions" ?

try in Dolphin right click a folder -> open with -> other -> and entering gwenview
