I'd like to test out viewing my security cameras on my new echo show devices. I've followed the documentation, and when asking Alexa to show the porch camera, she replies with "Getting porch camera" and almost immediately after replies with "Porch camera not responding".
I've tested the RTSP stream URL and verifies it works in VLC, and also works from outside the network the cameras are on (I'm using the no-ip.com DNS service instead of the camera's IP).
Digging into the docs a bit more, it mentions "Interleaved TCP on port 443 (for both RTP and RTSP)". Does that mean that my no-ip domain needs to be using SSL? If that's the case, is that also true if I won't be publishing the skill to the public? It's just for home cameras.
