Code:
rtmpdump -r "rtmp://46.28.53.160/live" -a "live" -f "WIN 19,0,0,226" -W "http://www.janjuaplayer.com/resources/scripts/eplayer.swf" -p "http://www.janjuaplayer.com/embedplayer/cnn5623/3/600/400" -C S:OK --live - y "cnnkxsm?id=46549&pk=7f829e2cc45201330a0c9f47466f245c68ab27c7bcb9f020d4eab8ae66bf6762"
