ChristianConstantNel · 2023-03-09T05:35:59Z

Did some more testing,

Crash seems to happen once controller get's initialised.

ThibaultBee · 2023-03-09T07:27:08Z

Hi,
Thanks for reporting the issue.
Unfortunately, I don't understand the reproduction steps, you just open the application and it crashes? Is that it? Or do you have an example to provide?

ChristianConstantNel · 2023-03-09T07:29:20Z

Hi,

I have a basic app, the main page has a button to navigate to the example LiveViewPage.
Once you click on that button to navigate to the page, the app crashes.

It seems to be when the controller gets initialised.

ThibaultBee · 2023-03-09T07:30:56Z

Could you share your application with us? so we quickly debug it.

ChristianConstantNel · 2023-03-09T07:41:11Z

Sure,

Hi,

Just a follow up.

Tested your example app, and app still crashes.

Another update:

Tested example app on an HTC one phone, everything worked.

Issue might be Samsung related?

ThibaultBee · 2023-03-13T11:08:25Z

Hi,

This issue is not going to be easy.
I am not sure it is Samsung related as their are no specific device features involve at this point.
It seems there is an crash in openssl internally. All I can find about a similar issue: hhttps://github.com/openssl/openssl/issues/11885. Unfortumately, it is not solved.
I could try to upgrade to openssl 3.0.8 (current is openssl 3.0.7) but not sure it will fix anything.

Also what method throws this crash?

Could you try to reproduce it with the native library as it would be easier to debug https://github.com/ThibaultBee/StreamPack/suites/11387220558/artifacts/586054880

ChristianConstantNel · 2023-03-13T11:12:41Z

Thanks for the reply,

I'll test the native library and let you know.

It's the initialise method on the controller that throws the crash.

ChristianConstantNel · 2023-03-13T11:33:04Z

Just tested the native app, and everything worked fine.

ThibaultBee · 2023-03-13T13:23:40Z

As it is described in this bug, it seems to be related to a race condition.
We won't be able to debug this.

ChristianConstantNel · 2023-03-14T04:56:50Z

Do you have any suggestions for how we can go about trying to fix this?

We really love your package, but cannot use it without Samsung support.

ThibaultBee · 2023-03-14T09:41:17Z

I understand, but I am sorry to say that I don't see anything to fix the issue you face.

ChristianConstantNel · 2023-03-14T09:49:16Z

I understand.

Do you think if we build a native view for android that shows the streamPack view inside our flutter app, that it might work?

ThibaultBee · 2023-03-14T09:55:02Z

This is what this library is doing

ChristianConstantNel · 2023-03-14T12:57:14Z

So there is no way to work around this issue?

ChristianConstantNel · 2023-03-14T13:04:10Z

Quick update:

Tested it on a Samsung Galaxy S9 Plus, and it worked.

All the phones that had this issue ran on Android 8.0.0

ThibaultBee · 2023-03-28T14:06:15Z

Hi,

I don't have a phone with Android 8.0.0. I just tested with a Pixel 6 Android 8.0 emulator but it does not crash.
We can't fix this issue.

This issue is supposed to be fixed in the main. It was due to a force unwrap of a null value when calling (stopPreview or stopStream while controller has not been initialized).

About your initial ssl issue (the one with CRYPTO_STATIC_MUTEX_lock_write), I still have no clue why this is happening. Anyway, we have updated ssl version since last time, could you try to reproduce this issue?
