Hello,

Amarok crashes frequently when approaching the end of the song, say in the last 10 seconds. The behavior is not reproducible, neither are files that played fine one time immune the next.

It is not related to directory or format, e.g. it crashes between songs of the same album (mp3 or flac) or completely different songs (format, directory).
It happens randomly, maybe every 10 tracks.

Phonon backend is gstreamer, which uses alsa.
Fade In and Out are disabled.

Amarok 2.8.0 / KDE 4.11.3 / gstreamer 0.10.31 / gstreamer 1.2.1 / Linux 3.12.1 / Arch
All packages up to date, https://www.archlinux.org/packages/

These are the last few lines of amarok -d
[code]
amarok: BEGIN: void ProgressWidget::redrawBookmarks(const QString*)
amarok: found 0 timecodes on this track
amarok: END__: void ProgressWidget::redrawBookmarks(const QString*) [Took: 0s]
amarok: MPRIS2: Album image location is KUrl("")
amarok: MPRIS2: Queueing up a PropertiesChanged signal

KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/florian/.kde4/socket-horus/kdeinit4__0
[\code]

Anything else I can provide?

Regards,
Florian

EDIT: s/arts/alsa/

Please try disabling Replay Gain and Fadeout.

Actually, Phonon uses Pulseaudio, which uses alsa, there is no such thing as arts anymore.

Check that you have Pulseaudio installed, as apparently sometimes Arch doesn't install it, but it should be default on Arch: https://wiki.archlinux.org/index.php/PulseAudio

Typo, please replace arts with alsa. Of course, arts is long dead and buried.

Pulseaudio is not installed and for the time being I've no intentions to do so.

Fade In/Out is already disabled. Replay Gain was set to track, it's disabled now.

I've changed the Phonon backend to VLC, no crashes so far. Switching back to gstreamer, let's see...

Ok, it still crashes with ReplayGain disabled, using the gstreaner backend:

Code: Select all

amarok: MPRIS2: Queueing up a PropertiesChanged signal

(amarok:2629): GStreamer-CRITICAL **: gst_value_init_and_copy: assertion 'G_IS_VALUE (src)' failed
KCrash: Application 'amarok' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/florian/.kde4/socket-horus/kdeinit4__0


and you have PA installed? Also please make sure you have the gstreamer 0.10.x plugins, the 1.x ones don't work with the current Phonon backend release yet

As I said, PA is not installed.

Playback works fine, I don't think it's a missing plugin.
These are the plugins installed for gst 0.10:

Code: Select all

extra/gstreamer0.10 0.10.36-2
    GStreamer Multimedia Framework
extra/gstreamer0.10-bad 0.10.23-5
    GStreamer Multimedia Framework Bad Plugin libraries (gst-plugins-bad)

*sigh* you really should install Pulseaudio, as all your problems stem from there...

No reason to *sigh*, there is a reason I don't use pulseaudio: viewtopic.php?f=19&t=118119

But you're right, amarok does not crash anymore, it just stops at the first 10s of a song, but much more frequently then it used to crash. Result is more or less the same...

Based on what you've observed above, I would suggest simply using the VLC backend. The GStreamer code in question is responsible for the crash, but it is unlikely the GStreamer developers will be interested in fixing it as they will be working on the 1.x code.

Well, I would report this as a packaging error to Arch, as it works perfectly fine with PA and the gstreamer backend in Kubuntu. So far we have repeatedly reports by people using Arch where there are problems, so I strongly suspect some serious packaging error.

FWIW: Phonon needs to be built with PA support, as suggested by the Phonon developers.

Hello,

there is a bug report here :
