Hi,

I want to achieve AES-256 encryption with webrtcbin (so webrtcbin uses
AES-256-encoded SRTP packets). As I see from the source code (correct me if
I'm wrong) webrtcbin uses DTLS and that only has AES-128. Is it possible to
change this? To make a pipeline that uses an AES-256 encoder and disable
webrtcbin's DTLS encoding? Any solution would work as long as it achieves
AES-256.

Thanks!
