Howard noted that it would be impossible to generate a working rtmpdump command
line for ustream.tv server. I think this is not the case.

Granted that post is quite old, but the issue with rtmpsrv persists. Using
rtmpsuck output you can in fact generate a working rtmpdump command

$ rtmpdump -r rtmp://ustreamlivefs.fplive.net/ustream4live-live/ -W http://stat
ic-cdn1.ustream.tv/swf/live/viewer.rsl:354.swf -y stream_live_1_1_12632253 -v -
o a.flv

However as the other user noted this server causes rtmpsrv to choke.
