BGE Video Textures not showing up in exported .app

Question

I've created a scene in BGE which involves some video textures I made by using a script to swap image textures with videos that I assigned as properties to each object. Everything runs fine and great when I play the game in BGE itself, but when I try and export the game as ann .app, the video textures are blank. I've already tried packing all my external data into the .blend, but I think since the videos are assigned in the properties panel, they are not being included for some reason. What is causing this and how can I make it export properly?

---

Still no luck. I tried exporting the app to the same place my .blend is saved and still no video in the .app. I am still a novice at this so forgive me if Im not articulating well.

For reference here is the script I am using to play the videos in the .blend

Answer 1

The VideoTexture module expects external files. It does not work with internal data blocks unless explicitly provided by Python call.

Therefore "Pack External Files" will not solve your issue. It increases the size of your distribution as you need to distribute the external files (as separate files) anyway.

I suggest following:

• Perform "Make Paths Relative" before distributing
• Ensure to distribute your VideoTexture source files where they are (relative to the start blend file).
