Hi, could you also provide logs from your side to get the investigation started?
Hi @Samaa-Amin , sorry for late reply, could you provide us these info?
- Could you reproduce this issue consistently?
- Is this flickering for the UI/background color/CSS or for the actual video stream? I can see the video tile part is flickering but not sure if the actual video stream is flickering. It could also be possible that the video stream is good but the position of video tile is switching frequently.
I also noticed this error in your logs:
failed to get audio device for constraints {"audio":{"echoCancellation":true,"googEchoCancellation":true,"googEchoCancellation2":true,"googAutoGainControl":true,"googAutoGainControl2":true,"googNoiseSuppression":true,"googNoiseSuppression2":true,"googHighpassFilter":true,"deviceId":{"exact":"default"},"sampleRate":{"ideal":48000},"sampleSize":{"ideal":16},"channelCount":{"ideal":1}}}: NotAllowedError: Permission denied MeetingManager failed to select audio input device on join PermissionDeniedError: Permission denied by user
Could you also ensure you allow the microphone permission when you try to reproduce this issue? Thank you.
Hi @xuesichao ,
-
yes it happens consistently, I could reproduce it on component library react meeting demo & on my own code.

I believe it's not a UI or tile position problem as this issue happens on both demo and on my code, however the tils Grid in my code is customized and the ui is completely different from the demo.
Thanks for response. We have not been able to see any errors in the log, but may see if we can procure that device. If you have time you could help us better narrow down whether it is a video/UX issue by running the demo in https://github.com/aws/amazon-chime-sdk-js .
@hensmi-amazon sorry for the delay, I couldn't reproduce the issue on this demo https://github.com/aws/amazon-chime-sdk-js
