Error : netstream.failed rtmpdump

[mounaime10]

hello,
My problem I want to download a video, but it shows me "netstream.failed".

Here is the command used:

rtmpdump -r "rtmpe://s1oeoq2ag2cdmr.cloudfront.net/cfx/st" -a "cfx/st" -f "WIN 11,9,900,117" -W "http://www.alphorm.com/fp/flowplayer.rtmp-3.2.11.swf" -p "http://www.alphorm.com/video/1224/94" -y "mp4:FR_130/FR_130_01_01.mp4%3FExpires%3D1415296551%26Signature%3DeExqm1AjO4zoouhiwJ8b4KNZf8ivWK3Pkmqo5zhVNav5~guGgtZNYotLzBZ-LlqzWO6UwnD4Gb5QYf~GdDeKqrEwYKmPYFKQ2WRxMRySfMoOohnbyW-ayG~~ZSFyac0MmeoiEk2eW8-uBpV2PVgAmC4YqcvNF7s5jqo7SQ7NiYk_%26Key-Pair-Id%3DAPKAJF2PMCJPGKXG2GEA" -o "C:\Users\ADAM\Desktop\RTMPDump\output\video.flv"
