twitch.tv NetStream.Authenticate.UsherToken

[wral]

Hi,

i have a problem with watching twitch.tv streams using rtmpdump.

my command line:

rtmpdump -r "rtmp://199.9.255.135/app/jtv_qJJzRT___TOJ0zOE"--swfVfy "http://www-cdn.jtvnw.net/widgets/live_embed_player.r4fa4a6b0df617f1cff79b6f6fbd7c6fa01047d9e.swf?channel=OnGameNet&referer=&userAgent=&channel=OnGameNet" -v -V | vlc -

it retrun:
INFO: Connected...
ERROR: Closing connection: NetStream.Play.Failed

in debug mode i can see:

...
DEBUG: Property: <Name:              level, STRING:     error>
DEBUG: Property: <Name:               code, STRING:     NetStream.Play.Failed>

You must supply
a valid token via NetStream.Authenticate.UsherToken>

packet which i sniffed (wireshark) when played stream via browser : http://pastebin.com/1b6kdM2E

the intresting part of this :

!NetStream.Authenticate.UsherToken............>eae 5cabba60a1ac4c3b8523cfa92b9d007f98ae8:{"swfDomains ": ["justin.tv", "jtvx.com.", "xarth.com", "twitchtv.com", "twitch.tv", "newjtv.com", "jtvnw.net", "wdtinc.com", "imapweather.com", "facebook.com", "starcr.afting.com"], "streamName": "jtv_qJJzRT___TOJ0zOE", "expiration": 1357907539.68525, "server": "video3-1.lhr01"}

any ideas how can i send the NetStream.Authenticate.UsherToken using rtmpdump?

i am begginer so i would be grateful if someone would find a time to help me.
