Settings to be given when creating SRTP transport. Application should call pjmedia_srtp_setting_default() to initialize this structure with its default values.
Specify the usage policy. Default is PJMEDIA_SRTP_OPTIONAL.
Specify whether the SRTP transport should close the member transport when it is destroyed. Default: PJ_TRUE.
Specify the number of crypto suite settings. If set to zero, all available cryptos will be enabled. Default: zero.
Specify individual crypto suite setting and its priority order.
Notes for DTLS-SRTP keying:
- Currently only supports these cryptos: AES_CM_128_HMAC_SHA1_80, AES_CM_128_HMAC_SHA1_32, AEAD_AES_256_GCM, and AEAD_AES_128_GCM.
- SRTP key is not configurable.
Specify the number of enabled keying methods. If set to zero, all keyings will be enabled. Maximum value is PJMEDIA_SRTP_MAX_KEYINGS.
Default is zero (all keyings are enabled with priority order: SDES, DTLS-SRTP).
Specify enabled keying methods and its priority order. Keying method with higher priority will be given earlier chance to process the SDP, for example as currently only one keying is supported in the SDP offer, keying with first priority will be likely used in the SDP offer.
RTP sequence rollover counter initialization value for incoming direction. This is useful to maintain ROC after media transport recreation such as in IP change scenario.
The previous value of RTP sequence rollover counter. This is useful in situations when we expect the remote to reset/maintain ROC but for some reason, they don't. Thus, when we encounter SRTP packet unprotect failure during probation, we will retry to unprotect with this ROC value as well. Set prev_rx_roc.ssrc to 0 to disable this feature.
RTP sequence rollover counter initialization value for outgoing direction. This is useful to maintain ROC after media transport recreation such as in IP change scenario.
Specify SRTP transport user data.
