Thanks a lot for your feedback! It appears that ffmpeg 4.1.1 is not available from the backports for Ubuntu 18.04 LTS.
In a VM running Debian Buster, I installed ffmpeg v. 7:4.1.1-1, and it *does* play the video without crashing, as previously on 18.04. Unfortunately, it is not possible to install the packages from Buster on 18.04 due to a too low libc version. Thanks, Albrecht. --- The debug output w/ libavcodec-extra57-dbgsym on 18.04 is (for vlc; same crash location for mplayer and xine): albrecht@deneb:~$ LANG=C LC_ALL=C gdb vlc GNU gdb (Ubuntu 8.1-0ubuntu3) 8.1.0.20180409-git Copyright (C) 2018 Free Software Foundation, Inc.
