[arch-dev-public] Qt 4.5 and its problems
Hi all, I just have put Qt 4.5 into testing. It should be compatible to 4.4 in most aspects. But we should have a look at the qt apps and see if anything broke. For example Psi crashes on typing a message when spell cheking was enabled. This could be easily fixed by recompiling it. QtCurve has some problems with the rendering of tabs. But I expect an updated version soon. KDE itself seems to work fine. But there might be some rendering problems especially with plasma. The main problem was phonon: * Qt has its own version of phonon included ** it is slightly different to the one provided by KDE ** KDE cannot compiled against this version (can be fixed by a symlink to the right include dir) * The Qt version only supports the gstreamer backend ** gstreamer seems borken. It is able to play ogg etc. but fails on mpeg/mp3 (I have every plugin installed) * one could enable phonon in qt but remove the relevant files after install. With some symlinking magic and moving files arround this might even work. ** But this would introduce a circual dependency; phonon and qt depend on each other * So, for now phonon is disabled within Qt. The downside is that video support in webkit is disabled, too. But webkit seems to only work with gstreamer anyway. Well, that's the current status. If anyone has a good idea about this let me know. -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@jabber.archlinux.de WWW http://www.archlinux.de

There is something wrong with your system then, I just pacman -S gstremer0.10-plugins and I have support for mpeg/mp3. So this is weird to me.

I allways get something like this: http://users.archlinux.de/~pierre/tmp/gstreamer-mpeg.png I tried kaffeine, totem and dragon. Dragon often just shows nothing. With all three the xine backend works fine. I tested a lot of different files...allways the same result. -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@jabber.archlinux.de WWW http://www.archlinux.de

Wow, that looks like something out of my nightmares... that is a car, right? And not some giant robot face coming to eat me?

Just a little update. In short: it's a mess. Somehow phonon-4.3.1 from Qt and KDE are very similar but have some differences. ATM I try to get KDE working with Qt's phonon. I had a almost working pacakge in my staging dir when I noticed that kdemulimedia does not compile anymore; in addition to this dragon is linked against xine-lib. And I thought phonon was invented to not depend on specific backends... -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@jabber.archlinux.de WWW http://www.archlinux.de

Just letting you know that I had to rebuild qgit against Qt 4.5 so you can move that at the same time. Allan

Thanks. There are still some ninor issue with for example handling of utf8 filenames. So I it might stay in testing for a while. I finaly gave up the fight against Qt's phonon. It's not really compatible with the one from KDE. This should be fixed upstream somehow. Till then we'll have to live with webkit without phonon support. -- Pierre Schmitz Clemens-August-Straße 76 53115 Bonn Telefon 0228 9716608 Mobil 0160 95269831 Jabber pierre@jabber.archlinux.de WWW http://www.archlinux.de
