Local Video is taking about a minute to be displayed on iOS 15.1

[ameriles]

What happened and what did you expect to happen?

After I join a meeting, my local video tile (LocalVideo component) appears for a fraction of a second, and then it dissapears.
Remote attendee is not getting any video from my end neither.
After a minute (aproximately), the local video tile begins displaying correctly and the remote attende start receiving it.

If I toggle my local video off, and then I turn it on again, I experience the same exact behavior: I should wait for about a minute for my local video tile starts displaying the video.

The iPhone camera status indicator (at the left of the battery icon), blinks between orange and green during the minute the video tile is not showing any video and becomes steady green when the video starts showing (as expected).

I am facing the exact same issue. It takes time for video to start on ios mobile device.
I can see the red video icon flickering at address bar as if it is trying to get hold of video stream.

Browser logs

The Chime SDK for JavaScript outputs the following message when the attendee was dropped from the meeting at 22:37:32.

[Error] WebSocket connection to 'wss://signal.m3.ue2.app.chime.aws/control/f2c61fa5-b95d-48e9-93a1-5969ea320706?X-Chime-Control-Protocol-Version=3&X-Amzn-Chime-Send-Close-On-Error=1&X-Amzn-Version=2.24.0&X-Amzn-User-Agent=ios-15' failed: The operation couldn’t be completed. Socket is not connected

The WebSocket status code 1006 often means that the browser kills a WebSocket connection for unknown reasons.

Next steps

According to Known browser and compatibility issues, starting a local video in iOS 15.1 has been failing due to the following Safari issues:

• In iOS 15.1, Safari and iOS Chrome tabs crash when starting a WebRTC video call with the H.264 format
  https://bugs.webkit.org/show_bug.cgi?id=232416
• Error the encoder in case we cannot create a RemoteVideoSample
  https://bugs.webkit.org/show_bug.cgi?id=231505

The Chime SDK for JavaScript 2.24.0 includes a workaround for these issues, but I wonder if there's a regression.

Can you check if you can reproduce the same issue in the Chime SDK for JavaScript serverless demo or the Chime SDK component meeting demo?

@ameriles Is this still an issue on your side, I tested on iOS Safari 15.3 with our react meeting demo with 2.12.0 component library version and my video loads up fine so looks like fixed with newer updates. Closing this issue due no activity further. Please feel free to re-open if you still face the issue.
