sorry it's a mistake
Code:
rtmpdump -r "rtmp://89.185.235.165/vod/" -a "vod/" -f "WIN 15,0,0,223" -W "http://www.playo.tv/js/jwplayer6/jwplayer.flash.swf" -p "http://www.playo.tv/video/single-yoyo-string-tricks-semifinals-1447.aspx" -y "mp4:akc_0000001447_1080p.mp4" --live -o "2014-11-27_11-40-33_mp4_akc_0000001447_1080p.flv"
don't forget '--live' because for me it stop without '--live'
