Hi,
so the paramters are ok so far and you just need to add a output paramter (-o or | player -) to download or play that stream.Like this..
Code:
rtmpdump -r rtmp://82.145.43.51/data4//tt1 -W http://www.3patti.net/tv/player.swf -p http://www.3patti.net/tv/ri.aspx | "C:\Programme\VideoLAN\VLC\vlc.exe" -
