Dear all,
I want to modify pjsip for support video call ( needed only for negotiate in
context : invite -> 200Ok --> ACK).
I have modified as follow :
- In endpoint.c, i added pjmedia_endpt_create_audio_sdp(),
pjmedia_endpt_create_video_sdp() into pjmedia_endpt_create_sdp() to
create 2 thread: audio and video.
+ status = pjmedia_endpt_create_audio_sdp(endpt, pool,
&sock_info[0], 0, &m);
if (status != PJ_SUCCESS)
return status;
sdp->media[sdp->media_count++] = m;
/* The remaining stream, if any, are videos (by convention as well) */
for (i=1; i<stream_cnt; ++i) {
status = pjmedia_endpt_create_video_sdp(endpt, pool,
&sock_info[i], 0, &m);
if (status != PJ_SUCCESS)
+ pjmedia_endpt_create_sdp() in pjsua_media.c, pjsua_core.c and
pjsual_call.c just change stream_cnt=2;
- Result:
+ Making a video call to Xlite: Accept Video call in Xlite, Xlite sent
200OK to me, then pjsip send ACK to Xlite, Xlite send 200OK,
After pjsip send Bye immediately.
+ Making a audio call normally.
- Here is the INVITE, 200 OK and BYE session when making a video call:
