For the info: i am using vlc 1.1.5 and phonon-vlc is latest from git Created attachment 54515 [details]
New crash information added by DrKonqi
amarok (2.3.2) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.1
- What I was doing when the application crashed:
I had just installed phonon-backend-vlc 0.3 and had put it as the first option in Phonon. Then I started Amarok and it crashed.
- Custom settings of the application:
Using VLC as a backend for Phonon.

Same problem here. Backtrace looks exactly the same! Amarok is from yesterday and Phonon-VLC from today, both from git. KDE 4.6 beta2 // Qt 4.7.1 // VLC 1.1.5 from OpenSuSE Packman Repo I don't know, if it's relevant, but I'm using Pulseaudio. Confirmed by duplicate. The problem apparently is in libvlc. Can't confirm this here, using current Amarok 2.4-git and phonon-vlc-backen from git, VLC built from stable branch 1.1.4-git, KDE 4.6 beta 2 on Kubuntu 10.10. Let's check what our VLC guy thinks about this. *** Bug 259706 has been marked as a duplicate of this bug. *** [Comment from a bug triager] From bug 261241 (KDE SC 4.5.90): - What I was doing when the application crashed: I just swithed phonon-vlc backend up in sound&video configuration, hoping to make my soundcard work under KDE 4.6 RC1. then knotify kept crashing many times. even I closed the setup page. *** Bug 261241 has been marked as a duplicate of this bug. *** Created attachment 55675 [details]

amarok (2.3.90) on KDE Platform 4.5.95 (4.6 RC2) using Qt 4.7.1
- What I was doing when the application crashed: starting amarok - but also knotify is crashing directly after switching to phonon vlc backend

knotify4 (4.0) on KDE Platform 4.5.95 (4.6 RC2) using Qt 4.7.1
- What I was doing when the application crashed: This is strange the knotify crashes continue after switching to phonox- xine backend (amarok is working right now with xine-backend) but the knotify crashes seems still to be caused by the phonon-vlc backend . For the mometn i just do usual work with the desktop (Browser, Email,amarok in the background )

as an additional comment - after switching the vlc itself from the original videolan repository to the vlc version in Packman/Opensuse 11.3 - the backend is stable and works - also knotify does not crash anymore. The phonon-backend-vlc Version is the same 0.3.1-1.1 from KDE:Unstable:Playground Repo for Opensuse 11.3 Yeah, a crash in libvlc_media_player_new means that VLC does not find any plugins, which is really a packaging issue. If someone could talk to the opensuse team, that would be great. Leaving the bug open, so we do not forget to nag them until it is fixed ;) Created attachment 56775 [details]

knotify4 (4.0) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.1
- What I was doing when the application crashed:
Installed phonon-backend-vlc from source from the kde repositories. I have no other backends installed for phonon. Phonon was crashing my whole KDE sessions, but now it just segfaults.
Reading through the bug, it looks like something is missing from this source...

Actually a terminal output would be very nice, ideally with the following environmental vars: export PHONON_DEBUG=5 export PHONON_VLC_DEBUG=5 *** Bug 267992 has been marked as a duplicate of this bug. *** Created attachment 57781 [details] Console output from start digikam Following request from Dario Andres (comment #2 in bug 267992), "crashreportdigikam.txt" is attached Environment var's export PHONON_DEBUG=5 export PHONON_VLC_DEBUG=5 set. Your crash is coming from a broken setup (apparently your vlc plugins are built against a different version of libvlc (supposedly 1.x as you are using 1.2). Nothing we can do about that though. It confirms that the crash is due to missing (or in your case unloadable) plugins. Setting priority and stuff to minor as it is not technically a bug in phonon-vlc. I haven't the slightest idea how my vlc plugins are built - I just download and install opensuse 11.4 beta's and RC's. Reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise. *** Bug 268958 has been marked as a duplicate of this bug. *** Just a heads up, in 0.4.0 a warning appears for GUI applications when libvlc fails to initializes. Not the most perfect of solutions, but good enough for now. *** Bug 276287 has been marked as a duplicate of this bug. *** *** Bug 277594 has been marked as a duplicate of this bug. *** *** Bug 276288 has been marked as a duplicate of this bug. *** *** Bug 292279 has been marked as a duplicate of this bug. *** Is this still valid for the latest 0.6.2 version of the vlc backend? Apparently all reports are about prior versions. If this is still reroducible we would need a more recent backtrace. with vlc 2.0 it does no longer crash but correctly error out on _new and phonon displays an error message accordingly. also from a quick test it seems the application also will not crash after that but simply not produce any output, which is the intended behavior. resolved from phonon pov |
