To specify stop time use/add -B
time in sec. For other parameters, try rtmpdump --help
example:
Code:
rtmpdump -r "rtmp://imavex.fc.llnwd.net/imavexpush" -a "imavexpush" -f "WIN 13,0,0,214" -W "http://www.streamotor.com/player/mediaplayer-5.10-licensed/player.swf" -p "http://nrbnetwork.tv/Pages/watch_online.aspx" -y "universal11" -o "c:/2014-07-28_10-06-11_universal11.flv" -B 20 -v
