[Bug 1654018] Re: mpd segfaults playing m4a (aac) audio
Ok, so I've tracked this down to mpd picking up a different version of libavutil which I built some time ago from source: ldd /usr/bin/mpd | grep local libavutil.so.52 => /usr/local/lib/libavutil.so.52 it's picked this up in preference to the stock version in /usr/lib/x86_64-linux-gnu/ - if I comment this version out then the problem is resolved. ** Changed in: mpd (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654018 Title: mpd segfaults playing m4a (aac) audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpd/+bug/1654018/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1654018] Re: mpd segfaults playing m4a (aac) audio
Well I've only just completed the update to 14.04 which took a few days to get sorted so I'd like to have that running and stable for a while first before contemplating the next one. Only additional thing I can add at this point is that it was working fine in 12.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654018 Title: mpd segfaults playing m4a (aac) audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpd/+bug/1654018/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

mpd 0.18.7-1 is very old, can you upgrade to Ubuntu 16.04 and see if the bug has been fixed there? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654018 Title: mpd segfaults playing m4a (aac) audio To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mpd/+bug/1654018/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
