Nest Hello video feed incorrect aspect ratio
**Describe the bug**

Somewhere between version 3.2.0 and 3.2.2, the video feed from my Nest Hello doorbell camera begins outputting stretched video in 16x9 format instead of 4x3. Version 3.2.0 is the last version that outputs 4x3 video for me.

**To Reproduce**

Steps to reproduce the behavior:

1. Install version 3.3.0 or 3.2.2.
2. View camera feed in Home app. Video output is stretched and in 16x9 output. 
3. Revert to version 3.2.0 (version 3.2.1 will not start a stream on my system for whatever reason).
4. View camera feed in Home app. Video output is correctly displayed in 4x3 output. 

**Expected behavior**

Video output for Nest Hello cameras output in 4x3 aspect ration.
