I think that too.

Then the opposite order could be ok:

- Implement a version of getaddrinfo and getnameinfo suitable for ffmppeg's

- Drop the IPv4-only code.

This would require a separate test for the IPv6 multicast structures and

In fact, I missed the point: all code in ffmpeg that uses the network do so
by creating an udp: or tcp: URL. The code is already separated and grouped
all in the same place.

I just looked at Ronald's code, and I am wondering about his
inetaddr_resolve function: as far as I can see, it does exactly the same as
getaddrinfo, only with a different API. Is it so?

If it is, why not keep the getaddrinfo API? This would make less code, and
in particular, no extra code at all in the good case (= modern
standard-compliant OS).
