Vertical video calls from some element-android devices are distorted

During video calls between element-web and element-android users, the element-web user will see an extremely distorted picture if the element-android's device is oriented vertically.

If the android user rotates their phone horizontally, the distortion goes away.

This behavior has been tested on five phones:

Pixel 3a with stock Android 11: DISTORTED
Pixel 3 with CalyxOS Android 11: DISTORTED
Pixel 4a with stock Android 11: Not distorted
Google Pixel (gen1) with stock Android 10: Not distorted
Unihertz Jelly2 with stock Android 10: Not distorted

Testing was performed with a combination of accounts, homed to matrix.org and mssj.me. mssj.me is currently running Synapse 1.29.0. Android apps were installed from either the Google Play store or F-Droid, and are up to date with their respective repositories. Element-web was running in Firefox, using both a self-deployment as well as the app.element.io deployment.

This is a duplicate of [this issue for element-android](https://github.com/vector-im/element-android/issues/3033) as this has crossover requirements in order to replicate.
