Crashing/ANR during live stream on some devices

[ThibaultBee]

Hi,

Unfortunately we don't have these smartphones to reproduce the issue. Could you provide a full logcat please?
Does it happen randomly?
Is this 3 differents issues?

[sadashivsinha]

Yes its 3 different issues but all are related to live stream itself.
Here is full logcat of all 3 issues.

**Does it happen randomly?
**
Yes sometimes it happens when we live stream for more than 10-15 seconds
Sometimes it happens when we stop the stream manually
Sometimes, randomly it happens while initialising

Ok.
If it is 3 differents crashes, could you open 3 different issues with:

• the method you call before getting the crash
• the video and audio settings
• full adb logcat not just the stacktrace (we don't even know the type of the exception and the third one we don't even know what is happening...)

[sadashivsinha]

I cant send adb logcat as I am sending errors from users from crashylitics

[ThibaultBee]

Ok, I understand.
We can't do much about it... We will read the code for the first and second issues to check if something is wrong but we cannot guarantee anything.
About the third one, there is a crash in libhwui and libc which are system libraries. At the state, we can't do anything about that.

[ThibaultBee]

Hi,

What version do you use?

About the first issue, the CodecSurface Future does not answer because there is a lock in the encoder provider. I can get the Future to timeout but I would like to understand how it can happen.

About the second issue, there is a try/catch block around startStream/nativeConnectStream, it should not crash. See

api.video-reactnative-live-stream/android/src/main/java/video/api/reactnative/livestream/ReactNativeLiveStreamView.kt

Line 103 in 6ce902b

internal fun startStreaming(requestId: Int, streamKey: String, url: String?) {

[sadashivsinha]

I am using latest version v1.1.0

It happens on some devices, sometimes ANR and sometimes crash.

Steps :-

1. Start livestream
2. Wait 10-15 seconds
3. Crash or ANR

Sometimes crash happens at start itself and sometimes at stop.

[ThibaultBee]

Hi,

We have made fixes in v1.1.2 which might fix these issues.
Feel free to reopen this issue if you still face similar issue.
