But I found the decision and i want to share with you.
1) Create a "new folder" in admin panel.
2) Upload an empty file with filename yourtitle.flv
3) Create ".htaccess" named file in your "new folder" from ftp-client
and add this
4) open your gallery and go to your/folders/structure/new folder from menuRedirect 301 /content/your/folders/structure/new folder/yourtitle.flv http://streamingserveraddress.com/filename.flv
and you will see a streaing video.
Also it will be useful to add parameters from iv-admin to your "new folder"
settings.startmode=image&thumbnails.thumbnailscroller.enabled=false&controls.maincontrols.enabled=false
&image.imagebuttons.enabled=true&image.closebutton.enabled=true
