a linked list of avfilter structs needs a "next" pointer in each
such next pointer makes them incompatible with being in (shareable)
read only memory

Awnsering whenever a program halts or runs forever is
On a turing machine, in general impossible (turings halting problem).
On any real computer, always possible as a real computer has a finite number
of states N, and will either halt in less than N cycles or never halt.
