It is the 2nd parameter because if I call in the java intelij debugger srtp_create(session, null) it works. I did print the policy .... it is not null & the deprecated field == null so it cannot be that bad param.
I do call:
libSrtp.srtp_crypto_policy_set_rtp_default(rtpCryptoPolicy);libSrtp.srtp_crypto_policy_set_rtp_default(rtcpCryptoPolicy); I did look at the 'C' code and unless I miss something I think I got the correct values and srtp_valid_policy should not fail with BAD_PARAM there. Then, I did: rtpCryptoPolicy.setSec_serv(SrtpSecServ.sec_serv_conf_and_auth.getValue()); // I was unable so far to map the enum with jna thus I used the enum - int conversion rtcpCryptoPolicy.setSec_serv(SrtpSecServ.sec_serv_none.getValue()); final var srtpPolicy = new srtp_policy_t(); srtpPolicy.setAllow_repeat_tx(0); srtpPolicy.setRtp(rtpCryptoPolicy); srtpPolicy.setRtcp(rtcpCryptoPolicy); srtpPolicy.setKey(srtpKey); srtpPolicy.setWindow_size(128); So far - I think I match the +/- same steps as the test/rtpdecoder.c But then the session is created when 1st rtp pkt is received: session = new srtp_ctx_t.ByReference(); final var srtpSsrc = new srtp_ssrc_t(0); // I used the ssrc from the rtp pkt - same error. By default the constructor is setting type to: SrtpSsrcType.ssrc_any_inbound.getValue(); srtpPolicy.setSsrc(srtpSsrc); final var srtpErrStatus = libSrtp.srtp_create(session, srtpPolicy); I'm getting BAD_PARAM ....Calling manually in the debug libSrtp.srtp_create(session, null); gives OK .... I just noticed that there is a: srtp_set_debug_module method but when I used it I get fail as status code. I'm trying to see if I can activate that and hope it might print some useful info

Do you mean this?https://github.com/cisco/libsrtp/blob/main/srtp/srtp.c#L2975 Is the first parameter NULL? The call to srtp_valid_policy() can also return that here:https://github.com/cisco/libsrtp/blob/main/srtp/srtp.c#L326 Or are you making another call that is failing? In any case, the best way to find it is to read the C code to see what conditions return that result.

I'm trying to use the library in java. I have wrote all jna mapping's required. When the code is executing create_session I'm getting SRTP_ERR_STATUS_BAD_PARAM
I do not see where my error is & enabling logs in the library may help. Any suggestions ? Thx.
