**Describe The Problem:**
Upgrading to UniFi Protect v2.0.0-beta.2 appears to have broken conversion of video files to be played on iOS devices.  Things were working beautifully before that update. The streams do work fine in the Protect iOS app, as well as in the Home Assistant plugin

**To Reproduce:**
Upgrade to UniFi Protect v2.0.0-beta.2
