A site can rtmpdump but just only few seconds

[benny]

Hi all,

I have found a stream using rtmpdump to watch...

rtmpdump -r "rtmp://solive.wni.co.jp/live" -s "http://weathernews.jp/framework/current/mws_streaming_video.swf" -p "http://weathernews.jp/solive24" -a "live" -y "livestream1" -v | vlc -

original website: http://weathernews.jp/solive24/

but it just run for 2~3 seconds and then the rtmpdump will exit ...

(-v options shows too long but just some extract to here)....
