There’s more to security protocol design than just blindly running everything through AES-128.

Cisco’s released an SRTP implementation on GitHub under a BSD-ish looking license:

That’s reinventing RTCP, which is already in Live555.

I’m not finding anything in Live555 that does automatic retransmission when an RR comes in indicating that packets were lost, but Live555 does at least give you the mechanisms to detect this and cope with it.
