Author: Camille Oudot <[email protected]> Committer: Camille Oudot <[email protected]> Date: 2015-02-09T13:51:27+01:00 modules/rtpengine: return the new SDP in an AVP if the new module param `write_sdp_pv` is set to a valid $avp() or $var() specifier, the SDP returned by rtpengine in the offer/answer operations is returned in the specified pv instead of the message body --- Modified: modules/rtpengine/doc/rtpengine_admin.xml Modified: modules/rtpengine/rtpengine.c --- Diff: https://github.com/kamailio/kamailio/commit/e6252246ea8056e06115d82a57372c8f241164a2.diff Patch: https://github.com/kamailio/kamailio/commit/e6252246ea8056e06115d82a57372c8f241164a2.patch --- diff --git a/modules/rtpengine/doc/rtpengine_admin.xml b/modules/rtpengine/doc/rtpengine_admin.xml index 4a1ea6f..7a01b0d 100644 --- a/modules/rtpengine/doc/rtpengine_admin.xml +++ b/modules/rtpengine/doc/rtpengine_admin.xml @@ -260,6 +260,26 @@ modparam("rtpengine", "force_send_interface", "10.3.7.123") </programlisting> </example> </section> + <section id="rtpengine.p.write_sdp_avp"> + <title><varname>write_sdp_avp</varname> (string)</title> + <para> + If this parameter is set to a valid AVP specifier, the + SDP returned by rtpengine in the offer/answer operations + is returned in the specified SDP instead of the + message body. + </para> + <para> + There is no default value. + </para> + <example> + <title>Set <varname>write_sdp_avp</varname> parameter</title> +<programlisting format="linespecific"> +... +modparam("rtpengine", "write_sdp_avp", "$avp(sdp)") +... +</programlisting> + </example> + </section> <section id="rtpengine.p.rtp_inst_pvar"> <title><varname>rtp_inst_pvar</varname> (string)</title> diff --git a/modules/rtpengine/rtpengine.c b/modules/rtpengine/rtpengine.c index 5ff6f36..ff9223d 100644 --- a/modules/rtpengine/rtpengine.c +++ b/modules/rtpengine/rtpengine.c @@ -211,8 +211,13 @@ static int *rtpp_socks = 0; static int setid_avp_type; static int_str setid_avp; +static str write_sdp_pvar_str = {NULL, 0}; +static pv_spec_t* write_sdp_pvar = NULL; + + char* force_send_ip_str=""; + typedef struct rtpp_set_link { struct rtpp_set *rset; pv_spec_t *rpv; @@ -282,6 +287,7 @@ static param_export_t params[] = { {"setid_avp", PARAM_STRING, &setid_avp_param }, {"force_send_interface", PARAM_STRING, &force_send_ip_str }, {"rtp_inst_pvar", PARAM_STR, &rtp_inst_pv_param }, + {"write_sdp_pv", PARAM_STR, &write_sdp_pvar_str }, {0, 0, 0} }; @@ -853,6 +859,16 @@ mod_init(void) setid_avp_type = avp_flags; } + if (write_sdp_pvar_str.len > 0) { + write_sdp_pvar = pv_cache_get(&write_sdp_pvar_str); + if (write_sdp_pvar == NULL + || (write_sdp_pvar->type != PVT_AVP && write_sdp_pvar->type != PVT_SCRIPTVAR) ) { + LM_ERR("write_sdp_pv: not a valid AVP or VAR definition <%.*s>\n", + write_sdp_pvar_str.len, write_sdp_pvar_str.s); + return -1; + } + } + if (rtpp_strings) pkg_free(rtpp_strings); @@ -1962,6 +1978,7 @@ rtpengine_offer_answer(struct sip_msg *msg, const char *flags, int op, int more) bencode_item_t *dict; str body, newbody; struct lump *anchor; + pv_value_t pv_val; dict = rtpp_function_call_ok(&bencbuf, msg, op, flags, &body); if (!dict) @@ -1978,14 +1995,28 @@ rtpengine_offer_answer(struct sip_msg *msg, const char *flags, int op, int more) if (more) body_intermediate = newbody; else { - anchor = del_lump(msg, body.s - msg->buf, body.len, 0); - if (!anchor) { - LM_ERR("del_lump failed\n"); - goto error_free; - } - if (!insert_new_lump_after(anchor, newbody.s, newbody.len, 0)) { - LM_ERR("insert_new_lump_after failed\n"); - goto error_free; + if (write_sdp_pvar!= NULL) { + pv_val.rs = newbody; + pv_val.flags = PV_VAL_STR; + + if (write_sdp_pvar->setf(msg,&write_sdp_pvar->pvp, (int)EQ_T, &pv_val) < 0) + { + LM_ERR("error setting pvar <%.*s>\n", write_sdp_pvar_str.len, write_sdp_pvar_str.s); + goto error_free; + } + + pkg_free(newbody.s); + + } else { + anchor = del_lump(msg, body.s - msg->buf, body.len, 0); + if (!anchor) { + LM_ERR("del_lump failed\n"); + goto error_free; + } + if (!insert_new_lump_after(anchor, newbody.s, newbody.len, 0)) { + LM_ERR("insert_new_lump_after failed\n"); + goto error_free; + } } } _______________________________________________ sr-dev mailing list [email protected] http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev
