Basically, you're not supplying enough information to diagnose the problem. We would need some or all of: * Your /etc/apt/sources.list file. * The exact version of the ffmpeg package (dpkg -l ffmpeg | cat). * The output of "apt policy ffmpeg". * The output of "aptitude why libopenal1". * Any interesting files in /etc/apt/apt.conf.d/ which may affect package selection (especially the treament of Suggests and Recommends). >From the non-working system, of course. Though you may find the output of "aptitude why libopenal1" to be informative on the working system.
