App crash on iOS build when decoding a PNG image through Unity when Rive plugin is included

[attewd]

When loading png images through the https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequestTexture.html and the rive plugin is included in the project, the app will crash on iOS.
On android it works correctly. Rive itself doesn't need to be rendering anything while the crash happens.

This appears to be due to the following libpng functions sharing the same name within Unity’s own libpng and the libpng included in the rive-unity plugin:
_png_riffle_palette_neon
_png_do_expand_palette_rgb8_neon
_png_do_expand_palette_rgba8_neon

The unity version used is Unity 6000.0.74f1

Should these be included in the https://github.com/rive-app/rive-runtime/blob/main/dependencies/rive_png_renames.h file?

Hello, you're right. It's most likely related to the png renames. Could you share which version of the plugin you're using?

Hey @damzobridge we tested with v0.4.2 ja v0.4.3-canary.105 and crashed with both.

Thanks for confirming. Could you try this version and let us know if the crash still occurs:

https://github.com/rive-app/rive-unity.git?path=package#v0.4.3-canary.102

Thanks!

I tried:

Crashes with https://github.com/rive-app/rive-unity.git?path=package#v0.4.3-canary.102

Doesn’t crash with https://github.com/rive-app/rive-unity.git?path=package#v0.4.3-canary.125
