I started testing my Alexa SmartHome IP Camera skill using the new The Toshiba 4K Ultra HD Smart LED TV and found that it does not seem to display/render RTSP/IP camera feeds above 1080p when using the Alexa Smart Home camera skills.
The exact same RTSP camera feeds work fine on:
- Echo Show
- FireTV 4K (2nd and 3rd gen)
- FireTV Cube
This is a 4K TV and should be able to display IP camera feeds above 1080p.
