As for the crash, it looks like it comes from an abort signal, but I couldn't find anything that may be calling it.

I have never experienced this in my development machine.

The app

The app is the Bluecherry Client.

The videos are initialized at the app start. Could this be the root of the issue? On Linux and Android, I've experienced crashes when doing so on startup and fixed by starting videos with a certain delay.

The video is a RTSP stream.

did this fix your issue? https://github.com/bluecherrydvr/unity/commit/09bb2c723aef0018705813152a47129affa63627 i think the crash is due to mpv not being initiated yet

[bdlukaa]

did this fix your issue?

As I said, I can not reproduce this on my testing machine. It is happening only to some of our customers.

i think the crash is due to mpv not being initiated yet

I can add a 1 second delay after mpv is initialized on macOS

[abdelaziz-mahdy]

Let me know if that was enough to fix it, for I have a MacBook but no crashes happened to me.

I think the delay will be a good workaround, but a proper waiting for initialization will be the cleaner route

Will check if it can be implemented or not, no promises here

[bdlukaa]

I'm not sure if there is any waiting for initialization. MediaKit.ensureInitialized() isn't a Future that can be awaited.

[abdelaziz-mahdy]

Yes I checked that, but I still want to look into it , maybe it takes time or a listener can be attached and await on it

[ShadrackOngera]

I also get the crash, and the app closses completely. I am developing on ubuntu

Hi, any updates on this? I'm also having the same issue on a build of the flutter app using the github action runner. Building it locally works fine.

Logs on stdout/stederr:

2024-07-26 23:55:54.947 my_app[63399:5923509] VideoOutput: enableHardwareAcceleration: true
Assertion failed: (group_index >= 0), function m_config_cache_from_shadow, file m_config_core.c, line 554.
[1]    63399 abort      ./my_app

[DefEnge]

After further investigation with @Bonfra04 we found out that changing the Mpv.framework inside "APP.app/Contents/Frameworks" with one provided from an App.app builded from local machine instead of Github Action, fixed the abort error. Regardless it isn't a proper fix because the Github action still outputs a bad build of App.app that contains the abort error.

[DefEnge]

Me and @Bonfra04 found out that the issue causing the abort error was the way our action would zip the app, it seems that using the "zip" command instead of "7z" caused the issue. We noticed that the same behavior applied even to the example app of the media-kit when using the "zip" command the app crashes with the abort, meanwhile using the 7z the app works properly.
