Media Player Showing Clear Color

OK so this one is confusing. I am trying to use a media player to play a video in a UI Widget.

However when I play the game in PIE or in a package build the video does not work at all.

I can see the video for 1 frame then it goes to the clear color in the media texture.

I know it is going to the clear color because I set it to hot pink and that is what I see:

BUT if I load up the media player in the editor and hit play I can see in the preview port that everything is working and the video renders.

I have seen numerous threads about the file paths and everything but this seems to be something different…

Help!

OK I figured this one out on my own… None of the tutorials I followed mentioned opening the media source in BP. You need to do that before you can play it.

Yay!!

You need to Open Media Source before you play the media. If you do not it will go to the texture clear color.
