The Best Practices are documented by Microsoft: https://technet.microsoft.com/library/security/ms12-006 Essentially, a chunk of ciphers, used across multiple TLS versions, are considered insecure. Note, this kb is from mid 2013, well before poodle.

When I tried to connect with my client using curl, I'm not able to connect, but if I do the same call on the remote machine locally, I can see that it connects. So I'm pretty sure that it is a network issue, but just not sure what it is? Even trying on the remote host, I get the same error if I give the actual IP address of the machine!

In my program I am attempting to replicate the pipeline above, however I have an issue which I suspect is related to connecting the dynamic or "sometimes" source pad of decodebin2 to the autovideo sink.
