            Bug ID: 228772
           Summary: getUserMedia() constraints incorrectly interpreted
           Product: WebKit
           Version: Safari 14
          Hardware: Mac (Intel)
                OS: macOS 11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebRTC
          Assignee: webkit-unassigned at lists.webkit.org

Tested with Safari 14.1.2 (mac mini 2018, macOS 11.5.1), Webcam Logitech C910

The issue can be reproduced with: https://jsfiddle.net/milen/srjkng6u/ 

The steps are: 

1) Click the button 'Add Cam HD'.

The expected result: the ideal video should be 1280x720 (16/9) and not smaller than 160x120.
The actual result: video is 160x90.

----
Safari incorrectly interprets these constraints

video: {
   width: {min: 160},
   height: {min: 120, ideal: 720},
   aspectRatio: {ideal: 16/9},
};

but this works fine

video: {
   height: {min: 120, ideal: 720},
   aspectRatio: {ideal: 16/9},
};

I don't expect just adding "width: {min: 160}" to mess up the HD constraints.
The above cases work fine in Chrome 92.
