right thing to do is define a "not set" value, whatever it is, and stick
with that. Right now it is 0, though perhaps only as an accident of
history. It makes more sense to have a special value for "not set"
different than 0, since 0 is a valid date.

FFmpeg tries to maintain API/ABI with Libav, and try not to break ABI as
long as possible. So you can try to use the deprecation guards as seen in
libavformat/version.h.
