Hi !
Thanks for your answer.
In fact, i forgot to have a look inside the *.app

It was the 1st thing to do to understand how it works !
It's a nice solution to put the *.flv directly in the *.app
But, for now it doesn't work with my project. Maybe i miss someting ?
In the *.app, there is a file named movie.swf
When i launch this file with flashplayer, everything works (the streams of *.flv is ok).
So i guess my path is ok.
But when i lauch the *.app, the stream doesn't work.
Is there a special path in *.app/Contents/Ressources ?
Of course, when i put my *.app and the *.flv in the same folder, it works !
So, it's a good solution for me ... But if i can find a way to embed directly the *.flv in the *.app, it would be perfet but it's not essential.
Again, thanx for you help !
