Cant get BINK videos to run on packaged build (ue5.7)

Hi, I’m trying to solve an issue for days with no progress. I am using bink files for some of my ui transitions/noise in the background(im plugging them into the material/ui). Everything works beautifully in PIE. But once packed, the videos dont’ play/aren’t in the game.

I saw there was an older thread about this, but I tried all the solutions in it and still no luck. I used the bink tool from epic to convert the filles. its using the default settings.

Basically, I have all my movies on Content/Movies.

Here’s some of the things I tried:

  • including them by force by including them in Additional Asset Directories to cook
  • including movies manually using the specific movies to package
  • Adding the folder Movies to “Additional Non-Asset Directories to Copy”
  • Tried Shipping build with full rebuild
  • Tested doing a build where I wait 5 seconds and then in level bp, call the media player of that video to play. But still no video to be seen
  • tested changing them from streaming to always loaded in the video file options, still no luck
  • i also check if the movies are actually there, using the “does file exist” and director exist, both say false(but i understand this might be because these commands dont work on io packed files)
  • in one of the latest packed staged builds, i do see the movie files in the staged folder on windows (content/movies)

if anyone can think of why this is not working, would be amazing. thank you!
