Video scaling changing after app first run

Video SDK
1

I want to use the video canvas at 4:3 scale, and it always looks correct after going through the camera permission screen. But every other time I open the app, with the permission already granted, the video canvas scale displays at 16:9.

I disabled Full HD within the Zoom Video SDK parameters and am subscribing to the canvas with the following parameter:
ZoomVideoSDKVideoAspect.ZoomVideoSDKVideoAspect_Original.

How can I always use the scale 4:3?

Hi @celioArc can you provide a code snippet of your apps video subscribe/unsubscribe logic?

Sure, Ticorrian.

lifecycle.coroutineScope.launch {
    viewModel.videoStreamingStateFlow.collect { state ->
        when (state) {
            is VideoStreamingState.Streaming -> {
                state.canvas.subscribe(
                    shareView,
                    ZoomVideoSDKVideoAspect.ZoomVideoSDKVideoAspect_Original,
                    ZoomVideoSDKVideoResolution.VideoResolution_720P
                )
                shareView.visibility = View.VISIBLE
                shareView.doOnLayout {
                    viewModel.sendCameraPreviewDimensions(it.width, it.height)
                }
                statusBarView.setVideoRecordingStatus(true)
            }

            is VideoStreamingState.NotStreaming -> {
                state.canvas?.unSubscribe(shareView)
                shareView.visibility = View.GONE
                statusBarView.setVideoRecordingStatus(false)
            }
        }
    }
}

Hi Ticorrian.
What logs do you want me to provide?
To verify which part of the code is saving the scale configuration incorrectly.

Hi @celioArc Can you print the value of `ZoomVideoSDKVideoAspect.ZoomVideoSDKVideoAspect_Original`

when (state) {
is VideoStreamingState.Streaming -> {

here---> println(ZoomVideoSDKVideoAspect.ZoomVideoSDKVideoAspect_Original)
state.canvas.subscribe(
shareView,
ZoomVideoSDKVideoAspect.ZoomVideoSDKVideoAspect_Original,
ZoomVideoSDKVideoResolution.VideoResolution_720P
)
shareView.visibility = View.VISIBLE
shareView.doOnLayout {
viewModel.sendCameraPreviewDimensions(it.width, it.height)
}
statusBarView.setVideoRecordingStatus(true)
}

is VideoStreamingState.NotStreaming -> {
state.canvas?.unSubscribe(shareView)
shareView.visibility = View.GONE
statusBarView.setVideoRecordingStatus(false)
}
}

I would like to verify the value is not getting nulled for any reason when you restart the app.
