The obvious way is to use per codec defaults where available and global
defaults where not.

avcodec_get_context_defaults2() could trvially do that if it was given the
codec id, that is no matter which APIs and implementations are used ...

there should be just one API

Note, ive not read the other replies in this thread, this one just looked
small and easy to awnser

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.
