[FFmpeg-devel] url_fopen creates IPv6 socket for url "rtp://localhost:XXX"

[Dominik Tomczak]

Hello

On Windows 7 Home Premium while using libavformat and opening url
"rtp://localhost:XXXX" (XXXX is a port number) I can see that 2 UDP sockets
are created but both are IPv6, not IPv4. Does anybody know why? I haven't
specified IPv6 in URL. Is IPv6 a default IP version in FFMpeg on Windows 7?
