Pick camera/resolution

After switching from S7 to S20 I noticed that the phone gets much hotter, and usually the video is of lower fps. 

Using discord on phone is rarely a good option due to how hot it gets and is less widely used. Making discord more usable to a wider population would benefit it, especially during this pandemic.

Please allow us to pick which resolution it is streamed on, since some phones can have absurd resolutions. Good options would be picking specific camera (selfie, normal,wide, telephoto), and fps if the dev side supports that.

An easy 'switch' for mobile-only that optimizes settings if the device runs too hot would also be nice. I frequently run discord as my webcam and pc as my mic, but it gets unbearable after 1h. While on my old phone I could run it longer duo to lower resolutions.
