Bug#498573: libqt4-dev: Please, enable Phonon support
Felix Homann
Version: 4.4.0-4
Severity: wishlist
Hi,
while Phonon support is one of the major new enhancements in Qt 4.4 it is disabled in the Debian package.
Thus it turns Qt 4.4 in Debian a little incomplete and in effect incompatible with packages on different platforms.
So, could you please enable it?
Thanks,
Felix

Hi! Qt4.4 ships phonon 4.1, but phonon is a extra thing that has seperate
releases as well. Phonon is in debian provided by the phonon source
package, that builds libphonon4 and libphonon-dev. The version provided
here is phonon 4.2, which is required by kde4.1.

what does it mean after all?
As far as I can tell the Qt4.4 interface is not working. Actually, I
don't even know whether it is an interface or if Phonon is just bundled
with Qt 4.4. At least, Qt and Phonon don't play together as they should
according to the Qt docs, e.g. the example applications won't build.
Qt applications are supposed to build on many platforms without
modification of the source code. They won't on Debian if Phonon is
involved. So how am I supposed to use phonon in Qt applications on Debian?
Similar discussions can be found here:
https://bugs.launchpad.net/ubuntu/+source/qt4-x11/+bug/253854
and here:

Seems like it's not only a Debian specific problem. But maybe there
should be mention in something like README.Debian or README.Phonon
1. that Phonon is disabled
2. how you can build Qt/Phonon applications (there's NO docs in
/usr/share/doc/libphonon* and Qt's Phonon docs don't work)
Kind regards,
Felix

It means that you have a bit newer phonon available supposed to be source and
binary backwards compatible with phonon 4.1 as shipped with qt4.4.

I have myself written a small media player without any problems. Please be
more verbose.

phonon is not disabled. phonon is just built from phonon source package, the
real upstream of phonon. Qt just embeds a copy of it.

Man, how to insert on the GUI from the folder menu within Office NT?
You either should receive a shell, or should turn off a driver to remove from
the clock on a coaxial ISA mailer.

thank you Sune for your reply. I'm very sorry I didn't answer earlier.
I've tried again building the musicplayer example from the Qt4 examples.
It builds but it doesn't work. I'm getting error messages of this kind:
Phonon::createPath: Cannot connect Phonon::MediaObject(no objectName) to
Phonon::AudioOutput(no objectName).
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend
plugin could not be loaded
Unfortunately, the example isn't build in qt4-demos either.
What's wrong?
Kind regards,
Felix

which phonon backends do you have installed ?

I cannot forward to a hard disk from the panel within ICQ 2.3.9, how does it
work?
First from Office and from the folder menu inside Photoshop NT you either must
digit on the connector on a cache, or need to ping the firewall for
uninstalling on the computer.

About the phonon backend error, see the discussion here:
http://bugs.archlinux.org/task/11070
Sune, I don't know if you'd consider this a problem with the Qt or
phonon packages, but it seems that by default Qt applications look for
the phonon plugins under /usr/lib/qt4/plugins/. However, Debian
installs them under /usr/lib/kde4/plugins/.
startkde takes care of that by setting the QT_PLUGIN_PATH environment
var. Something in there also causes ~/.config/Trolltech.conf to update
the "4.4\libraryPath" entry. Unfortunately, there's two problems with
this:
1. If a person hasn't run a KDE4 session at least once, Qt doesn't know
where to find phonon's plugins.
2. For some reason the "4.4\libraryPath" entry is getting flooded with
repetitions. A new pair appears each time a KDE4 session starts.
