"encrypted_rtp_extensions_" to match existing names might be better.

[joachim, 2017/03/23 00:04:33]

The "XXX_rtp_extensions_" members are lists of extensions (e.g.
"audio_rtp_extensions_") where the new member is a flag.

If you want to use a different name, what about
"enable_encrypted_rtp_extensions_"?
