Help for a dump

[Barbapapa]

Hi everybody,

I'm trying to save a video file from this url : http://www.wakanim.tv/video/NQ/1-le-...r-black-bullet

After passing the ads, we are redirect to :
http://www.wakanim.tv/video-streamin...#######&Id=###

I've tried to use rtmpdump with the following command :

rtmpdump -r "rtmp://wakanim.flash.internapcdn.net/wakanim/_definst_/mp4:video/BlackBullet01_720f" -W "http://cdn1.wakanim.tv/player/flowplayer.commercial-3.2.15.swf" -y "mp4:video/BlackBullet01_720f.mp4" -o "video.mp4" -T "#########"

with the token1 value for key instead of ######

I don't see where could be the problem, everytime i have the following error:
ERROR: RTMP_ReadPacket, failed to read RTMP packet header
and nothing is downloaded.

Any advice is welcome.
