[M] Change in osmo-mgw[master]: client: allow passing and receiving full SDP to/from MGW

by neels

neels has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-mgw/+/32163 ) Change subject: client: allow passing and receiving full SDP to/from MGW ...................................................................... client: allow passing and receiving full SDP to/from MGW Clients can continue to use the current way of providing the information contained in the SDP part. A client may also decide to directly provide an SDP string. That may be useful to send a list of payload types with mixed fmtp (e.g. two entries, one for AMR OA and one for AMR BE) or any other custom SDP that is not possible to be represented with the previous structure of struct mgcp_conn_peer: struct sdp_msg sdp = {}; sdp_audio_codecs_add(&sdp.audio_codecs, 96, "AMR", 8000, "octet-align=1"); sdp_audio_codecs_add(&sdp.audio_codecs, 97, "AMR", 8000, "octet-align=0"); struct mgcp_conn_peer verb_info = { ... }; sdp_msg_to_sdp_str_buf(verb_info.sdp, sizeof(verb_info.sdp), &sdp); osmo_mgcpc_ep_ci_request(my_ci, MGCP_VERB_MDCX, &verb_info,...); (TODO: sdp_msg, sdp_audio_codecs_add() and sdp_msg_to_sdp_str_buf() so far only exists in osmo-msc.git) If no SDP is present in the passed verb_info, the SDP part is composed as before from the mgcp_conn_peer members addr, port, ptime, ptmap, param. If an SDP string is present in the passed verb_info, ignore the data in the individual members, and directly pass the given SDP string instead -- the caller does not need to pass both the individual members and SDP, either one suffices. A client can read the full SDP response from the MGW, again for example to accurately parse a list with mixed fmtp for AMR like above, like this: /* Handling successful event after osmo_mgcpc_ep_ci_request(my_fi, my_notify_event): */ const struct mgcp_conn_peer *response_info = osmo_mgcpc_ep_ci_get_rtp_info(ci); struct sdp_msg sdp; sdp_msg_from_sdp_str(&sdp, response_info->sdp); for (int i = 0; i < sdp.audio_codecs.count; i++) printf("PT %u = %s %s", sdp.audio_codecs.codec[i].payload_type, sdp.audio_codecs.codec[i].subtype_name, sdp.audio_codecs.codec[i].fmtp); Related: OS#5723 Change-Id: Ib26b4d24546a9a9af65d4313fdf87cdeff9cbc22 --- M include/osmocom/mgcp_client/mgcp_client.h M include/osmocom/mgcp_client/mgcp_client_fsm.h M src/libosmo-mgcp-client/mgcp_client.c M src/libosmo-mgcp-client/mgcp_client_fsm.c 4 files changed, 83 insertions(+), 2 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-mgw refs/changes/63/32163/1 diff --git a/include/osmocom/mgcp_client/mgcp_client.h b/include/osmocom/mgcp_client/mgcp_client.h index 0fb5dee..c185971 100644 --- a/include/osmocom/mgcp_client/mgcp_client.h +++ b/include/osmocom/mgcp_client/mgcp_client.h @@ -83,6 +83,7 @@ }; struct mgcp_response { + /* The complete MGCP + SDP response.
