When package project, Media Texture won't play

Hi,

I’ve set up media texture with media player as well as blueprint using open source when beginning play the media player variable. I have some screens in the scene and I want them to run videos when I start playing.
It works perfectly fine when I just hit the play button. But when I package, It stays just black white.

Can someone help on this, please?
Thanks,

did you tick the “play on open” in the edia player?
and to be packaged your videos need to be in the content/Movies/ folder of your game
