Native Crash - Crash on Video Playback (Vulkan)

Vladnee · November 20, 2024, 6:01pm

Hi Unity Community,

I’m experiencing a crash during video playback on some Android devices, visible in the Google Play Console. The crash appears to be related to VideoPlayer and Vulkan integration. Below is the relevant stack trace:

Key Details:

Unity Version: 2022.3.52f1
Video Output: Using RenderTexture for video playback.
Issue: Crash occurs when VideoPlayer attempts to process frames (AndroidVulkanVideo::ProcessFrame).

What I’ve Tried:

Clearing RenderTexture with GL.Clear() before playback
Ensuring videos use MP4 (H.264) format.

Any insights or suggestions to address this issue would be greatly appreciated!

Hello,

From your logs I can gather info that you are using Mali GPU device. These devices have more limited support for texture formats than Adreno. Could you provide *.mp4 file you are using to reproduce this issue?

Have you tried reproducing issue with OpenGLES graphics backend?

Hello, thank you for your reply, please see attached files

We do not use OpenGLES, only Vulkan, so we have not tested it.

EngineEnjoyer · November 21, 2024, 11:53am

We looked into it and couldn’t reproduce it on our end. Could you provide minimal repro project or built apk file? What models of devices this issue is reproducible on? What other settings have you modified with this project? For our reproduction we tried clean project with same settings as you have provided in screenshots on Samsung A32

Thank you for looking into the issue. Unfortunately, I cannot provide an APK file at the moment as the root cause of the crash is still unclear. The problem seems to be related to a wide range of devices, particularly Mali and Adreno GPUs, which makes narrowing down the cause more challenging.

However, after updating to Unity 6, the issue was resolved.
