Please test current git head, filter_complex is a fairly 
new option that has seen some improvements since.

This is a very bad configuration option, 
don't use it.
(Install yasm if necessary, it is a small 
static binary.)

And please try to avoid this one, if you 
believe you need shared libraries, use 
only one run (with --enable-shared), 
alternatively compile without --enable-shared 
to not break your existing installation.
