ffmpeg | branch: master | Jordi Ortiz <nenjordi at gmail.com> | Tue Jul 24 19:59:53 2012 +0200| [f9a9a148622530cb02dbb81b31d951785f6d331a] | committer: Martin Storsjö

tcp: add port missing error message

Without this patch a user a bit absent-minded may not notice that
the connection doesn't work because the port is missing.
