I'm having a similar problem trying to switch to streaming over https. The video link works fine on roku using http, but https returns in debug:
Unspecified or invalid track path/url.
I've added to my roVideoScreen instance the following:
screen.SetCertificatesFile("common:/certs/ca-bundle.crt")
The https link works outside of roku. I wonder if it could be the fact I'm testing this on a non-standard port? The non-standard port works fine for https connections getting XMLs and whatnot, but I don't see any other reason why this won't work for streaming mp4.. any ideas?
