What's the possible side effect when I use PhotoCaptureSource. Auto to Initialize MediaCapture Settings?

Hello guys,

My app has MediaCapture function. I followed the microsoft official document to to Initialize MediaCapture Settings by using the PhotoCaptureSource. Photo.

In most cases, it worked well. But on a device, it did not work. After my troubleshooting, if I change PhotoCaptureSource. Auto, it will work.

I checked the official document PhotoCaptureSource Enum . It shows:

> Some video cameras have a separate photo stream that can capture still images at higher resolution than the video stream.

Does it mean that the camera on that device doesn't support 'a separate photo stream that can capture still images at higher resolution than the video stream'? Although I use the PhotoCaptureSource. Auto to solve the current issue, but will there be any side effects? If I use PhotoCaptureSource. Auto, will it be subject to some system-level settings or other things?

Best Regards,

Xavier

1. Does it mean that the camera on that device doesn't support 'a separate photo stream that can capture still images at higher resolution than the video stream'? Yes, from the document, this device doesn't support 'a separate photo stream that can capture still images at higher resolution than the video stream'.
2. but will there be any side effects?
There is no mention in the document, but it should have no side effects.
3. will it be subject to some system-level settings or other things?
I'm not sure about if it will be subject to some system-level settings or other things, I will ask the team about this to confirm it.

I've been waiting for a long time. Have the expert of Microsoft can answer the question '3. will it be subject to some system-level settings or other things?'?

Hi, based on feedback from team, currently, we didn't find that there is any side effects or it will be subject to some system-level settings or other things. But we still recommend that you can test your app across a variety of devices or scenarios to ensure that it behaves as expected.
