I too found this bug with Ubuntu 18.04 LTS on Nvidia Jetson TX2 system. Running ffplay :
ffplay /dev/video0 produces: dbus[9467]: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed in file ../../../dbus/dbus-message.c line 1362. This is normally a bug in some application using the D-Bus library. D-Bus not built with -rdynamic so unable to print a backtrace Aborted (core dumped) Workaround 1) from above solved the problem -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1775067 Title: D-Bus bug in 18.04 i386 SDL: arguments to dbus_message_new_method_call() were incorrect, assertion "path != NULL" failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libsdl2/+bug/1775067/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
