Description lafferx 2015-06-23 15:15:51 UTC

Application: amarok (2.8.0)
KDE Platform Version: 4.14.8
Qt Version: 4.8.6
Operating System: Linux 3.16.7-21-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
1. Add a stream that has gone offline to the playlist (for example this: http://pub7.sky.fm:80/sky_classical )
2. Play the stream. Next stream is chosen (if there are any) as the selected one is offline.
3. Try to play another stream in the playlist (can be the offline one). The application crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

Comment 1 Myriam Schweingruber 2015-06-23 17:41:58 UTC

Apparently you do not have debugging symbols installed, please do so and provide a better backtrace. See also https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#openSUSE
You need to install debugging symbols at least for Amarok, phonon and the phonon-backend you use.

FWIW: a first glance at the backtrace seems to indicate the problem is with some avcodec, not with Amarok, please make sure you have all necessary codecs installed correctly and do not try to play a video, as Amarok is an audio player.

Comment 2 lafferx 2015-06-23 18:23:36 UTC

Here is a better backtrace with phonon, phonon-backend-vlc and amarok debugging symbols installed. Also, the stream I used (http://pub7.sky.fm:80/sky_classical) used to be an audio stream which seems to have gone offline (I get a server not found response), so codecs shouldn't matter here.

Comment 3 Myriam Schweingruber 2015-06-24 00:18:39 UTC

Still, the Crash Handler indicates a problem with the avcodec, so definitely not an Amarok bug. Reassigning to phonon-backend-vlc, maybe they have an idea what is wrong.
Could you please specify which exact version of the backend you use?

Comment 4 lafferx 2015-06-24 10:30:45 UTC

Sure, the phonon-backend-vlc version is 0.8.2-16.3.

Comment 5 Myriam Schweingruber 2015-06-24 11:14:08 UTC

Thank you for the fast feedback

Comment 6 Myriam Schweingruber 2015-06-24 11:25:38 UTC

FWIW: the product is called Amarok (not AmaroK) since 2008 already :)

Comment 7 Harald Sitter 2016-06-04 12:20:54 UTC

That's a crash in libvlc directly, needs a big filed at the Videolan bug tracker
