Bug 228772 – getUserMedia() constraints incorrectly interpreted

• Status: NEW
• Component: WebRTC

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.
