You beat me to it. VLC works fine, its only Dragon Player that seems to have the issue. I installed every codec and library I could find and it still wont work.

With the GStreamer backend

With the VLC backend

**rjj** · Mar 10, 2014, 08:47 AM

I don't have any problems with Amorok and mp3 files, I even have sound in Dragon. The video is the problem. So I didn't think the Amorok question was relevant.

If I understood your answer right, I have to install the VLC backend and use that in stead of gstreamer.
That means install VLC. I didn't want to do that.
And it still leaves the question: why doesn't Dragon find any codecs?
Should I file a bug?

**Rog132** · Mar 10, 2014, 09:23 AM

It is always...

And it still leaves the question: why doesn't Dragon find any codecs?

I think that this is the problem:

debfx gstreamer0.10-ffmpeg has been removed from the archive and none of the others seems to be able to decode it. 09:33

So, there are missing bits and pieces...

The gstreamer0.10-ffmpeg /2/ has been removed because the Debian & Ubuntu decided to pick the Libav side /1/. There is the gstreamer1.0-(libav) (?) but it is not working with the Phonon/GStreamer (?).

Should I file a bug?

It's always a good idea to file bugs.

I had similar problems with Gwenview when it advance to play an mp4 file. I have filed a bug report 331901 at https://bugs.kde.org/show_bug.cgi?id=331901. I also did a fresh install after the beta came out and Dragon player does not work, but VLC does. I am wondering if it is caused by the KDE 4.12.3 packages that have been installed.

What I find puzzling is that Dragon player works on another 14.04 system that was installed some weeks ago and has all software updates.

**rjj** · Mar 10, 2014, 04:38 PM

Thanks everyone.
I marked this thread as solved. Installing VLC did the trick.
OTOH I still think there is a problem when the included videoplayer does not work out of the box

Pondering: How to solve the gstreamer problem

kubuntu-devel -- Kubuntu Developer Discussion: gstreamer0.10-ffmpeg and how we won't have it for 14.04

more good news

gstreamer0.10-ffmpeg was removed from the archive [1] because it does
not build with libav9 (it retracted the libavformat/url.h header).

gstffmpeg has a builtin libav copy that also fails to build [2],
supposedly because of gcc stuff.

so short of bringing back libav8 (which probably would raise security
concerns) we'll likely not be able to have gstreamer0.10-ffmpeg which
essentially means that whatever codecs were only provided by that
package (might have been quite a few) won't be there anymore and thus
a selection of file formats won't be able to play....

also, it was suggested that perhaps we should switch to phonon-vlc,
for which it may be "a bit" late in the cycle, plus ISO size continues
to be a problem.

much crap. eveywhere.

To resolve media problems with Gwenview I installed "phonon-backend-vlc". This also helped with Dragonplayer being able to work.

I was also wanting to convert an ogv file created from RecordMyDesktop to an mp4 file, and to do this I needed ffmpeg which I found was not available in the repositories. Also, none of the alternatives would do what I wanted. In the end, I decided to add the repository available from here. This version worked well for me and did all the conversions I needed.

**SteveRiley** · Mar 27, 2014, 07:43 PM

Rog, I see that your PPA has FFmpeg version 2.1.4 for Quantal and Saucy, and version 2.2 for Trusty. Severinsson's PPA offers the much older FFmpeg version 0.10 for Saucy and older, and a not-so-new 1.2.5 for Trusty. When I rebuild my T520, I would like to ditch the usual LibAV for FFmpeg, now that the project appears to have some new life. Do you use your own packages on a daily basis?

**Rog132** · Mar 28, 2014, 05:34 AM

About ffmpeg & libav

Do you use your own packages on a daily basis?

Yes.

ffmpeg & libav

Earlier: https://www.kubuntuforums.net/showth...l=1#post332936

The Jon Severinsson's FFmpeg PPA is offering 'upgrades' from the Libav to the FFmpeg. Note the compatibility !

...FFmpeg 0.7 is backward compatible with FFmpeg 0.6 and 0.5, as well as Libav 0.6 and 0.5; FFmpeg 0.10 is backward compatible with FFmpeg 0.8 and 0.9, as well as Libav 0.7 and 0.8; FFmpeg 0.11 is not backward compatible with any FFmpeg or Libav versions; FFmpeg 1.0 is not backward compatible with any FFmpeg or Libav versions; FFmpeg 1.2 is backwards compatible with FFmpeg 1.1, as well as Libav 9; FFmpeg 2.1 is backwards compatible with FFmpeg 2.0, but not any Libav versions...

My PPA is offering the FFmpeg installed side by side with the Libav. Applications are build either with the Libav or with the FFmpeg libraries.

Same application, thumbnailer, build with the Libav&FFmpeg libraries.

Yes, avconv did work but I needed to append one mp4 file to another and I could not find a way to do this with avconv. The procedures that I used to do this I recorded in Kontact, Popup Notes, but since the latest release of KDE 4.12.95 my notes.ics file cannot be accessed by Kontact. So KDE has taken one step backwards in this area

So, I was also wondering why Amarok, Dragon Player and SMplayer weren't working while running Kubuntu 14.04 beta 2 and found this.
My questions:
1) To have those programs working and also system sounds, like always, which package do I have to install?
2) ffmpeg was really removed from the repositories and will not be part of Kubuntu anymore? (I ask this because I was kind of waiting for packages to have audio and video working again)
3) Since I'm happy so far with SMplayer and Amarok, is there a way to install only phonon-backend-vlc without actually installing vlc?

If you haven't already, make sure you install "phonon-backend-gstreamer1.0".
