Movieplayer problem

I’m new to xojo. I tried to create a window which can embed a video inside.
So in the project, I drag an element of MoviePlayer in the window created.
But when I run the project, the video is showed in a seperated window called “debugvideo1”.
It isn’t showed inside the main window that I created.
What should I do?
I use the version xojo 2015r4 for linux. My linux is Ubuntu 14.04


How do you load the movie into the movie player?

Same problem here using raspberry

You may need to install GStreamer (as noted on the MoviePlayer doc page).

it does not help, the video is playing in a new window.

I did that. I am using Debian Wheezy for raspberry, but still the same problem.
