Hi, I would like to have my video streaming encrypted using SRTP. Looking at the ffmpeg documentation, seem like the encoding suites are limited as follows: ‘AES_CM_128_HMAC_SHA1_80’ ‘SRTP_AES128_CM_HMAC_SHA1_80’ ‘AES_CM_128_HMAC_SHA1_32’ ‘SRTP_AES128_CM_HMAC_SHA1_32’ How do I get AES-256 encryption?
