This is likely not video related; it is the dynamic linker complaining about
something.
Try running strace(1) with -f on your failing command. Perhaps by following
what files are being opened (i.e. open(2)) you can trace down the root
of the problem. And there may be other clues.
Enclosed below is the code from glibc-2.1.3/elf/dynamic-link.h where the
assert() is failing. Not clear why it would be failing.
Shots in the dark, but, if you can, run ldd(1) (with and w/o -r) and
objdump -p on the programs that are failing. Send the data to me,
strace too, if you like; (or the list, esp if the output looks promising).
Have you changed LD_LIBRARY_PATH or /etc/ld.so.conf recently?
This one appears tough; I'd try running a search on "linux bad dynamic tag"
search at www.deja.com ...
