I can definitely do that, but am curious about this. The codebase
already uses long long (see e.g ffprobe), and morally llabs returns
long long; hence I use it. As for the INT64_MAX, I do not have a
current example to know whether it is safe on all platforms, but
again, the "clean" solution is LLONG_MAX due to the type of llabs.
