Package: kdenlive Version: 16.04.3-1 Severity: normal Dear Maintainer,
I have a kdenlive project, HD 720p 25fps, with multiple tracks. On the first track (Video 1, MP4/H.264/AAC source with 24 fps), I can apply the `compand` filter as expected. On the second track (Audio 1, MKV/H.264/Opus source with 10 fps), when I do this, kdenlive crashes with a segfault in libavfilter. I'm not really sure whether kdenlive, libmlt or libavfilter are at fault here, feel free to reassign to these packages. A gdb session log is attached, a coredump (amd64, 594MB, gzipped to 22 MB) is available at https://rohieb.name/stuff/temp/kdenlive-avfilter-compand-segfault.core.gz Cheers, Roland -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'testing'), (170, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages kdenlive depends on: ii ffmpeg 7:3.1.1-2 ii kded5 5.23.0-1 ii kdenlive-data 16.04.3-1 ii kinit 5.23.0-1 ii kio 5.23.0-1 ii libc6 2.23-2 ii libgcc1 1:6.1.1-9 ii libgl1-mesa-glx [libgl1] 11.2.2-1 ii libglu1-mesa [libglu1] 9.0.0-2.1 ii libkf5archive5 5.24.0-1 ii libkf5attica5 5.23.0-1 ii libkf5auth5 5.23.0-1 ii libkf5bookmarks5 5.23.0-1 ii libkf5codecs5 5.23.0-1 ii libkf5completion5 5.23.0-1 ii libkf5configcore5 5.23.0-1 ii libkf5configgui5 5.23.0-1 ii libkf5configwidgets5 5.23.0-1 ii libkf5coreaddons5 5.23.0-1 ii libkf5crash5 5.23.0-1 ii libkf5dbusaddons5 5.23.0-1 ii libkf5filemetadata3 5.23.0-1 ii libkf5guiaddons5 5.23.0-1 ii libkf5i18n5 5.23.0-1 ii libkf5iconthemes5 5.23.0-1 ii libkf5itemviews5 5.23.0-1 ii libkf5jobwidgets5 5.23.0-1 ii libkf5kiocore5 5.23.0-1 ii libkf5kiofilewidgets5 5.23.0-1 ii libkf5kiontlm5 5.23.0-1 ii libkf5kiowidgets5 5.23.0-1 ii libkf5newstuff5 5.23.0-1 ii libkf5notifications5 5.23.0-1 ii libkf5notifyconfig5 5.23.0-1 ii libkf5plotting5 5.23.0-1 ii libkf5service-bin 5.23.0-1 ii libkf5service5 5.23.0-1 ii libkf5solid5 5.23.0-1 ii libkf5sonnetui5 5.23.0-1 ii libkf5textwidgets5 5.23.0-1 ii libkf5widgetsaddons5 5.23.0-1 ii libkf5xmlgui5 5.23.0-1 ii libmlt++3 6.2.0-1 ii libmlt6 6.2.0-1 ii libqt5concurrent5 5.6.1+dfsg-3 ii libqt5core5a 5.6.1+dfsg-3 ii libqt5dbus5 5.6.1+dfsg-3 ii libqt5gui5 5.6.1+dfsg-3 ii libqt5network5 5.6.1+dfsg-3 ii libqt5qml5 5.6.1-5 ii libqt5quick5 5.6.1-5 ii libqt5script5 5.6.1+dfsg-2 ii libqt5svg5 5.6.1-2 ii libqt5widgets5 5.6.1+dfsg-3 ii libqt5xml5 5.6.1+dfsg-3 ii libstdc++6 6.1.1-9 ii libv4l-0 1.10.1-1 ii melt 6.2.0-1 ii oxygen-icon-theme 4:4.14.0-1 ii qml-module-qtquick-controls 5.6.1-2 ii qml-module-qtquick2 5.6.1-5 Versions of packages kdenlive recommends: ii dvdauthor 0.7.0-1.4+b1 ii dvgrab 3.5+git20160707.1.e46042e-1 ii frei0r-plugins 1.4-3+b2 ii genisoimage 9:1.1.11-3 ii recordmydesktop 0.3.8.1+svn602-1+b1 ii swh-plugins 0.4.16+git20160602~repack1-2 Versions of packages kdenlive suggests: pn khelpcenter <none> -- no debconf information
