TVPublica - How to get rtmp?

[YRgB]

The webplayer is here: http://tvpublica.com.ar/vivo/

Until some time ago I was able to use this command to capture the stream

rtmpdump -v -r "rtmp://active.telecomcdn.com/canal7vivoflash/canal7vivoflash/livestream" -W "http://vmf.edge-apps.net/res/players/standar/StrobeMediaPlayback.swf" -p "http://www.tvpublica.com.ar/vivo/" -o "dump.flv -V"

now no longer works and returns this error

Can anyone give me help?
