Camera flashing and 'freezes' on iPhone X

[chrisedington]

Hi @AndrewShapovalov

Me again 😅 I found an issue where on two sets of iPhone X and using the sample, the camera flashes green colors and freezes.

Hi @chrisedington!

Thanks for the info. Do you have any chance to provide logs?

[chrisedington]

@AndrewShapovalov can try - what source or kind of logs would you be looking for?

Debug logs from Xcode (Debug area) while the problem happens.

Hi @chrisedington!

Some update from my side - tried to reproduce the bug on iPhone X with iOS version 16.1 but without luck.

I have same problem. I write Test Environment and Error log below.

Test Env.
Device:
iPhone 11, iOS 15.6.1

Video Resolution: 720x1280

Bug Reproduce

when preview screen's size is matched on iphone screen. It happened image capture action is too slow or flashing.

Debug Log:

2023-01-04 17:08:15.173949+0900 ivsTest[3973:200261] Execution of the command buffer was aborted due to an error during execution. Ignored (for causing prior/excessive GPU errors) (00000004:kIOGPUCommandBufferCallbackErrorSubmissionsIgnored)

...... above message is repeated

Hi @wizfinder, thanks for the report!

Is the same or any other error in the onBroadcastError event handler?

[AndrewShapovalov]

Hi @chrisedington @wizfinder! Me again.

It appears to be an internal issue, but since I am unable to reproduce it, could you please check the repository containing sample native apps that use the Amazon IVS Broadcast iOS SDK and see if you can reproduce the problem by running BasicBroadcast sample app?

When I build BasicBroadcast and run, I don't have errors. Only I have errors in ReactNative env with iPhone 11.
and
In iPad Mini(6 Gen.), I don't have errors in ReactNative env.

@wizfinder hi! Thanks for the update!

Do you face the same type of error by running Amazon IVS React Native Broadcast Example App?

Could you also provide detailed props configuration you pass to IVSBroadcastCameraView component (e.g. videoConfig, audioConfig, configurationPreset and others) please?

[wizfinder]

I don't face the same error with Aws IVS ReactNative Broadcast Example App.

I wrote test code below. if width and height value are less than about 300, it works well.

const videoConfig = {
   width:720,
   height:1280,
   bitrate: 7500000,
   targetFrameRate: 30,
   keyframeInterval: 2,
   isBFrames: true,
   isAutoBitrate: true,
   maxBitrate: 8500000,
   minBitrate: 1500000
 }

......

<SafeAreaView>
 <IVSBroadcastCameraView style={{width:"100%", height:"100%"}}  
 //<IVSBroadcastCameraView width={300} height={300}
       ref={cameraViewRef}
       videoConfig={videoConfig}
       onIsBroadcastReady={onIsBroadcastReadyHandler}
       onBroadcastAudioStats={onBroadcastAudioStatsHandler}
       onBroadcastError={(e) => console.log("onBroadcastError", e)}
       onBroadcastStateChanged={(stateStatus, metadata) => console.log("onBroadcastStateChanged", stateStatus, metadata)}
       cameraPreviewAspectMode={"fit"}
 />
</SafeAreaView>

@wizfinder @chrisedington I am facing the same issue too.

[AndrewShapovalov]

According to the answer you've provided, it appears that the issue might be within the project's codebase rather than with the package. Try experimenting with your component that utilizes the IVSBroadcastCameraView and configuration to identify possible issues.

I will also play around with the sample app using iPhone 11 to catch any related problems. @wizfinder

Also having this issue, I've not yet been able to find any form of workaround

Hi,

We had the same issue and found that setting the width and height of broadcast to 320 worked for iPhone6 and around 400->500 on iphonex. If not the component will flash or hang.

Have not looked into the underlying native code to understand what is causing it yet.

I have been testing a variety of configuration changes and it seems somehow related to the total number of pixels being rendered? I have been unable to find any workaround for the affected devices other than reducing streaming quality, so on iphone6/7 its 320p which would be great to increase :)

Anyone had any luck figuring it out?
