The version of libavutil which you have is from a different source, with a higher epoch version but a lower upstream version, and is no longer available from your selected repositories. In particular, it is not the same version as your other libav* libraries (as the snipped version information for libavformat indicates), and that mismatch is probably the source of the problem. Do you have any idea how this mismatched package version may have come about? I recommend that you explicitly install the "lower" version listed here (7:3.2-2), and see if your problem goes away. I don't know what tools you normally use for package installation and upgrade, but I would do that with the following command (in a root terminal): apt-get install libavutil55=7:3.2-2 -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
