What happens when the bug or crash occurs?

When you turn on a webcam with Vesktop, the camera resolution is automatically lowers to 432x240 at 30fps, I've witnessed it happening in real time from 1080p30 -> 240p using cameractrls when i enable my webcam in a voice call.

-Using the official Discord client, the webcam stays at 1080p.
-Using an OBS Virtual camera, the resolution stays at 1080p (however the camera occasionally appears black to other members of the call).

What is the expected behaviour?

I expect Vencord to NOT be able to change my webcams resolution. If i set my camera to use 1080p30 in the software (cameractrls), Vesktop should respect that.

How do you recreate this bug or crash?

1. Connect a webcam
2. Join a call
3. Enable the webcam
4. Observe the resolution

Request Agreement

• I have searched the existing issues and found no similar issue
• I am using the latest Vesktop and Vencord versions
• This issue occurs on an official release (not just the AUR or Nix packages)

This also happens on Windows 11 LTSC, and it causes my webcam to appear stretched vertically since im using a capture card for a camera and its picks the 480p option which is limited to 3:2.
