Hi everyone,

I’m trying to port a UE 4.27 game to MacOS and having a issue with startup movies not playing if they have audio. If I strip the audio from the video it plays fine, but any video with audio crashes on startup. The only log entry is “initializing media player”.

First. are you using Blepirnt or C++?
Try to rebuild the game, it can be a corupt file.
Here are something you can try

  1. Try it in UE 5 (Make a new project) if that works, then you can upgrade your project to UE5 (make a backup first)

  2. Try to make a new empty project and add the video to it and if it plays in the editor, try to bake the game and run the standalone game, it that also crash then, then try to reinstall UE 4.27

  3. Try to encode your video insoftware like “handbrake” to a format Mac understand.

If nothing off this works, then report this as a crash bug here:

I tried all that and it still fails. I noticed all my audio is AAC encoded, anyone have a working startup movie with Audio that they can tell me the encoding of the audio? Maybe change that encoding…
