Summary0002293: Long interface freezes when stopping Playback
DescriptionIf I select a clip in the project tree, play it in the clip monitor, as soon as I stop the playback the interface freezes. The same happens when playing the timeline. No Problems with only selecting clips.
Kdenlive is not usable for me at the moment (fedora x64)
Additional InformationInstalled latest MLT, FFMPEG and Kdenlive version from Git. Also tried the build wizard.

I have tried 1, 2 and 3 threads. All giving the same result.

I have made a short Screencap:

Maybe this helps: Openshot doesn´t show that behaviour.

I improved things in svn rev. 5942, could you please test?

Hmm, unfortunately this didn´t solve the problem. There doesn´t seem to be an improvement at all to me.

Okay, I have done a little bit of research now ;)
In addition to my Fedora install I have tried Kdenlive on the following Systems:
Ubuntu 11.10 (Build-Wizard)
Lubuntu 11.10 (Build-Wizard)
AV Linux 5 (As preinstalled on the distro)
Debian 6 (Build-Wizard)

On Ubuntu and Lubuntu I got the same problems as described in the Bug report.

Kdenlive on AV Linux runs as fast as hell, no problems here.
Same for Debian 6 (Although I had to compile Yasm manually because Debian repositoies are... well... always a bit outdated ;) ). Except of AV Linux where Kdenlive was pre-installed, I compiled Kdenlive with the same procedure on every system: http://mltframework.org/twiki/bin/view/MLT/BuildScripts [^]

And I noticed one big Difference in Kdenlives' appearance between the "bad" installs (Ubuntu and Lubuntu) and the well working ones (Debian and Av Linux): On the well working installs, Kdenlive showed up with a real KDE like interface appearance, while on Lubuntu, Ubuntu and Fedora it looks like some Clearlooks-Gnome-Like design. I attached two screenshots to the Bug report showing both variants.
So maybe this could be a hint what's going wrong here? Also AV Linux is a Debian based Distribution. So where could be the difference between Debian and Ubuntu/Fedora that makes Kdenlive work so well on Debian and so badly on other systems for me?

I have also attached a Debugger Output from a bad Kdenlive install on Lubuntu. I have only loaded a video file and did a little Stop-And-Go play.

Well, I´ve found the solution. It´s so f**king easy, but how could we know that?

I am using ALSA on my system. In the Kdenlive Playback settings I have selected ALSA as audio driver of cause and the audio device was set to default. This caused the freezes. Now I have set the audio device to my first analog output and the freezes have gone.
