I really don't understand, i've spend a lot of time on the options, adding some, removing some others and finally with just :
Code:
rtmpdump -r "rtmp://wakanim.flash.internapcdn.net/wakanim/_definst_" -y "mp4:video/BlackBullet01_720f" -T "##########" -o WAKANIM-videotest.mp4
it works !
Sorry that i've made a new thread about that and few time after i arrive to solve my own problem ^^"
Hope this will help somebody else at least
