Package: guvcview Version: 2.0.2+debian-1 Severity: important Not quite sure what is happening here, but there is a dependency problem which stops guvcview working because libavcodec.so.56 is not present.
I see Depends: libasound2 (>= 1.0.16), libatk1.0-0 (>= 1.12.4), libavcodec56 (>= 6:11~beta1) | libavcodec-extra-56 (>= 6:11), ... but libavccodec-extra-56 is not present in testing, and I can't see what else might provide that library. Anyway, on this system, no dependencies are broken, yet the libary is not present. $ guvcview guvcview: error while loading shared libraries: libavcodec.so.56: cannot open shared object file: No such file or directory # ls -l /usr/lib/x86_64-linux-gnu/libavcodec.so* lrwxrwxrwx 1 root root 20 Sep 22 17:54 /usr/lib/x86_64-linux-gnu/libavcodec.so -> libavcodec-ffmpeg.so ---------------------------------------------------------------------------------- -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.2.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages guvcview depends on: ii libatk1.0-0 2.18.0-1 ii libc6 2.19-22 ii libcairo-gobject2 1.14.2-2 ii libcairo2 1.14.2-2 ii libgdk-pixbuf2.0-0 2.32.1-1 ii libglib2.0-0 2.46.0-2 ii libgtk-3-0 3.18.2-1 ii libguvcview-1.1-1 2.0.2+debian-1 ii libpango-1.0-0 1.38.0-3 ii libpangocairo-1.0-0 1.38.0-3 Versions of packages guvcview recommends: pn uvcdynctrl <none> guvcview suggests no packages. -- no debconf information
