[iOS] Crashes on iOS AVPPluginGetRenderEventFunction

[IgorKubyshkin]

Hello. We've noticed some crashes after release our app in the AppStore. This happens when AVPPluginGetRenderEventFunction is called. Could you help us to resolve this? I attached crash logs and screenshot from xcode

Your Setup (please complete the following information):

• Unity version: 2022.3.32f1
• AVPro Video version (number and edition (trial/core/ultra/enterprise)): 3.0.6
• Operating system version: iPhone OS 16, 17
• Device model: iPhone, iPad

AVPPluginGetRenderEventFunction is only called when the plugin is initialised the first time a MediaPlayer component is created. The odd thing from your crash logs is that this is being called from Unity's render thread when I would expect it to be called from the main thread.

Unfortunately there is not enough information in the log files to work out what's going wrong and without a reproducible case a fix will not be possible. If you could provide as much information as possible around how you're using the player in your app that would be helpful.

I use the Media Player component as part of the some prefabs. Nothing special. They cannot be created outside of the main thread. I don't create any Media Player instances in my code directly. I just add it in a prefab through the Inspector window and then I create instance of it using Instantiate method.

[IgorKubyshkin]

In my case the Initialise() function usually calls in OpenMedia(), becouse I open videos in OnEnable() function before Start(). But not always in OnEnable, it can be executed in Start in some cases.

I can try to add Media Player component in my launch/first scene, where is no any references to Media Player. Just for initialization and static constuctor call, then check if this crash is gone

We are having the same problem, many of our iOS users crash with this error. This wasn't an issue before 3.X.

Did you come up with something? @IgorKubyshkin

[IgorKubyshkin]

I noticed that this happens quite often when calling Destroy media player (not at the time of media player initialization, as previously suggested). I can reproduce this crash in my project, but I havn't yet understood what needs to be done to avoid the error.

@IgorKubyshkin if you're able to share your reproducible case that would be great, please send a link to unitysupport@renderheads.com

In my case, the app stops crashing if I temporarily comment Native.AVPPlayerRelease(_player) in PlatformMediaPlayer.Dispose(). I will try to reproduce the error on an empty project, if get success, I will send the link

@MorrisRH I've just sent you a link to unitysupport@renderheads.com

@IgorKubyshkin thanks for the project. I've been able to reproduce the crash and identified the underlying issue. A fix will make it into the next release.

AVPro Video version 3.0.8 has been released. Please can you let us know if it has not fixed your issue.

[IgorKubyshkin]

I can confirm that my test project is no longer crashing. I need to update my app in the App Store and collect some statistics, hopefully this crash won't happen anymore.

[Chris-RH]

I'll close this for now. Please reopen it if your users are still having issues with the updated version.
