Bug in Unity 6: Cannot fall back to other approach if Unity fails to play a video

[achimmihca]

Actual behaviour

In Melody Mania, when Unity fails to load a video then libVLC is used as fallback.

This failed in Unity 6 because of a Unity bug: VideoPlayer.errorReceived callback is not fired such that Melody Mania cannot handle the issue.
This was working fine in Unity 2023.12.f1 (in this version, VideoPlayer.errorReceived was called as expected).

I opened a bug report, which has been confirmed by Unity (IN-94095). You can find a reproducible example on GitHub.
Let's hope they fix their broken platform.

Expected behaviour

If Unity fails to play a video, then Melody Mania should fall back to use a different approach.

For UltraStar Play, this is irrelevant because it does not use the fallback mechanism via libVLC.
If Unity cannot play the file then UltraStar Play cannot play the file.

Details

• Game version: Melody Mania v1.4.4-beta4
  • Note that Unity 6 was only used in the beta version of Melody Mania, not yet in a stable release.
  • Due to this bug, the next beta of Melody Mania will downgrade to Unity 2023.12.f1

Implementation hints

• Workaround: stay with Unity 2023.12.f1
