Bug ID: 396912
Summary: Infinite notifications 'An application needs
additional multimedia codecs'
Product: plasmashell
Version: 5.13.3
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Notifications
Assignee: k...@privat.broulik.de
Reporter: larr...@kde.org
CC: plasma-b...@kde.org
Target Milestone: 1.0
I'm getting infinite notifications in plasma saying "An application needs
additional multimedia codecs" and a button to install ogg vorbis decoders
(which I had installed). If I open the notification applet in plasma and clear
the whole notifications history, it's filled again with the same messages
instantaneously (at least 10 notifications/second, but it happens so fast it's
difficult to count).
This notification is the same that is shown when running
After some debugging, I found that this notification is run by phonon
executing:
/usr/lib/gst-install-plugins-helper "gstreamer|1.0|plasmashell|decodificador
Vorbis|decoder-audio/x-vorbis"
(this can be run manually to reproduce the message)
That command is run by PluginInstaller::addPlugin in phonon-gstreamer, when
calling gst_install_plugins_async .
It seems gstreamer has an internal loop that at some point calls the
Phonon::Gstreamer::Pipeline::cb_error callback. This calls
PluginInstaller::checkInstalledPlugins [see backtrace 1 below] and at this
poing, PluginInstaller's m_state is Idle, m_pluginList is empty and m_descList
is a list containing one string: "gstreamer|1.0|plasmashell|decodificador
Vorbis|decoder-audio/x-vorbis", so the condition (!allFound ||
m_descList.size() > 0) is true and so it tries to install the codec by running
the above command.
I set a breakpoint in
Phonon::Gstreamer::PluginInstaller::pluginInstallationResult and noticed that
the result is always GST_INSTALL_PLUGINS_SUCCESS. This makes sense, since I
checked gst-install-plugins-helper is trying to using packagekit to install
something that provides "gstreamer1(decoder-audio/x-vorbis)()(64bit)" and I
have the gstreamer-plugins-base package installed, which provides that
capability.
I tried replacing the binary /usr/lib/gst-install-plugins-helper with a symlink
to /bin/true to check if maybe each notification was somehow generating the
next one (for example, because plasma tried to play a sound and this would
fail, generate a new notification, which would try to play another sound...),
but no. Replacing the command with 'true' stopped the notifications, but I
could still see in gdb that it's executing it continuously as fast as the cpu
allows.
I was tempted to try to fix this by making Phonon:Gstreamer::PluginInstaller
have a check that doesn't try to install the same plugin more than once per
minute, or something like that, but the above test shows that this is not a
valid fix.
Btw, while trying to understand phonon's code I noticed that PluginInstaller's
m_pluginList is always empty as PluginInstaller::addPlugin(GstMessage
*gstMessage) is called in each iteration, but PluginInstaller::addPlugin(const
QString &name, PluginType type) is never called (which is the only method that
inserts anything into m_pluginList.
I wondered if maybe filing this bug entry for phonon, but I'm not sure and
since it's plasmashell the process trying to play sound I thought I'd start
here, and maybe later we can move it to phonon.
Any idea of what else to try? I'll leave plasmashell stopped in gdb as long as
I can in order to continue testing this, as this problem happened to me other
times and it's difficult to reproduce.
This all happens in openSUSE Tumbleweed with plasma 5.13.3, phonon4qt5-4.10.1,
phonon4qt5-backend-gstreamer 4.9.0, gstreamer 1.14.1, pulseaudio 12.0,
Frameworks 5.47.0 and Qt 5.11.1, but I've seen the problem with older versions
too (I can't recall the first time I had this problem, but it was many months
ago).
