I'm trying to use MP4 videos as backgrounds in the main menu and loading screen, but the VideoWidget fails to load them.

I've tested both direct paths to the video files inside the mod and files copied to the $saves: directory. Neither works.

The files are valid MP4s encoded with H.264/AVC and AAC audio, and they play normally outside the game. Re-encoding them didn't fix the issue.

The logs show errors such as VideoWidget: Can't load video stream, even when the file exists and the path is correct.

SCRIPT : [TSUI Video Debug] Requested path: $saves:TSUI_Main.mp4

SCRIPT : [TSUI Video Debug] FileExist: TRUE

GUI (E): VideoWidget: Can't load video stream $saves:TSUI_Loading.mp4

1. Create an MP4 video encoded with H.264/AVC and AAC audio (or whatever encode that should work).

2. Place the video in a mod directory or the $saves: directory.

3. Load the video using VideoWidget.Load() with the corresponding path.

4. Call VideoWidget.Play().

5. Check the logs. The video fails to load.

The VideoWidget should load and play a valid MP4 video when given a valid path to the file.
