Problem
When trying to stream my G6 PTZ camera to a Nest Hub using DashCast, I only see the DashCast logo. For a brief moment an URL referencing my Home Assistant instance is displayed, but then nothing loads.
Steps to reproduce
- Attempt to cast the G6 PTZ camera stream to Google Nest Hub via DashCast.
- The entity is correctly selected, and
mode: webrtc,mse is provided in the additional parameters.
- The DashCast logo displays but the stream never loads.
