Camera image is squashed to a square instead of cropped (DSLR via HDMI USB grabber) #260
Description
When using a DSLR camera connected via HDMI to a USB grabber, the live video feed in the circle appears squashed — a normally rectangular, landscape-format image is compressed into a square aspect ratio, rather than being correctly cropped or displayed.
The same hardware setup (DSLR + HDMI grabber) works correctly in Zoom, where the image is displayed with the correct proportions, suggesting that the USB grabber is not the source of the problem.
