Critical bug in EasyAR lib on Android

Question

The example project `HelloARVideo` from EasyAR_SDK_2.3.0_Basic_Samples_Android proves a critical bug in EasyAR library: attempt to scan the target named `idback` which should stream video results in the error:

W/IMediaDeathNotifier: media server died
E/MediaPlayerNative: error (100, 0)
E/MediaPlayer: Error (100,0)

...

E/MediaPlayerNative: pause called in state 0, mPlayer(0xc816f0a0)
    error (-38, 0)
E/MediaPlayer: Error (-38,0)

which probably means that the callback from VideoPlayer's `open` method is called before the player is ready. This is a critical issue.
The bug happens on Xiomi Mi5 (Android 8.0) or SAMSUNG Note 9 (Android 9.0). Happens when streaming URL is passed to VideoPlayer to open. Playing local videos is not affected.
Please fix as soon as possible.

All console logs after running the example project:

Hello，

Is it normal to test with other types of mobile phones?

Comments

I've tested on the following phones and the same example code works fine on them:
- Pixel with latest Android
- Samsung Galaxy J5 with Android 5.1.1
- HUAWEI P20 Lite with Android 8.0

 But as mentioned in the question, it fails to stream video on
- Samsung Note 9 (not sure which Android, could be 8 or 9)
- Xiomi Mi 5 (Android 8.0 OPR1.170623.032)

Could it be that the issue with Android 8?

UPD:
One more important detail:
the streaming was working fine on my Mi 5 earlier. Update to Android 8.0.0 OPR1.170623.032 broke streaming. So the issue could be connected to Xiomi's Android version.

---

I'm happy to have a call to provide more details about the issue. It is critical for me to fix it within the next 3 days. Please e-mail me if you'd like to have the call.

I've just tested streaming on HUAWEI P20 Lite with Android 8.0 and it works. This means it  could be connected to Samsung and Xiomi Android 8 versions only. This is only a suggestion, has to be tested.

One more important detail:
the streaming was working fine on my Mi 5 earlier. Update to Android 8.0.0 OPR1.170623.032 broke streaming. So the issue must be connected to Xiomi's Android version.

---

And one more detail:
the first error in the console of Android Studio is 'E/libc: Access denied finding property "camera.hal1.packagelist" ' which happens the moment  `camera.open(CameraDeviceType.Default);` is called, though the example project asks all the necessary permissions at app start. Could this be the origin of the bug with streaming?

I have the same issue, Android 8.1.0
