Environment:
iPhone 13/14, iOS 16, Chrome, Safari
Description:
We use WebRTC api to stream camera to <video>. We did some business logics according to stream's width and height.
But the height and width value swapped randomly.
Expected result:
video stream height is always larger than width on portrait mode.
Actual result:
video stream width height swapped randomly.
How to reproduce:
1.Visit on mobile https://yari-demos.prod.mdn.mozit.cloud/en-US/docs/Web/API/Media_Capture_and_Streams_API/Constraints/_sample_.Example_Constraint_exerciser.html
Click start button above "Requested video constraints:"
See the outputs in "Actual video settings":
"height" is larger than "width" in portrait mode
Repeat clicking start button and see the outputs multiple times.
You can see "height" will be smaller than "width"
