Apparently, on a windows machine you get a "trust this certificate"
pop-up
window and you are able to import the chromecast certificate.
That popup also exists in Linux. But it is not adequate to handle
insecure
algorithms, only unknown or mismatched certificates.
In Debian
there isn't such window. How to accept the chromecast certificate?
The TLS support within VLC is identical for Windows and Linux. The
difference
is the Windows version ships an older version of GnuTLS, than that in
Debian.
Presumably, the server is using SHA-1 certificate signatures - which are
being
phased out industry-wide, and no longer accepted by newer GnuTLS version.
I don't see how this is a VLC bug. It's actually working as intended. If
you
think the diagnostic is wrong, then it's a problem with GnuTLS.
I'm not sure this is a VLC bug, although I think it is odd that VLC 3 has
a Chromecast feature, but it isn't working. Maybe build vlc without
Chromecast support in Debian until Google and/ or GnuTLS has a decent fix
for this issue. Or make a workaround.
