Erlang DTLS SRTP extension support
Thu Apr 8 22:33:01 CEST 2021
There is a PR to add custom hello extensions  and PR specifically for
DTLS SRTP .
For WebRTC we should be able to dynamically select SRTP_AEAD_AES_128_GCM or
SRTP_AES128_CM_HMAC_SHA1_80 based on supported extensions in client hello.
I really hope otp 24 will add official support for DTLS SRTP. WebRTC is
massive and the change required in erlang is minimal (20 lines of code?)
