Hi Bemali
I just learn from the old thread from this email list, thanks Mude and Nanang
But now I only add SDP into invite, have not handle other part about
video, like media, etc..
This is my first part to add video media description into SDP, hope
this can help you to speed up your progress.
Add code into the pjmedia_endpt_create_sdp function in endpoint.c
/* Add part before assign sdp value to pointer */
pjmedia_sdp_media *mv;
sdp->media_count = 2;
mv = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_media);
sdp->media[1] = mv;
pj_strdup(pool, &mv->desc.media, &STR_VIDEO);
mv->desc.port = 4002;
mv->desc.port_count = 1;
mv->desc.fmt_count = 0;
mv->attr_count = 0;
mv->desc.fmt[mv->desc.fmt_count++] = pj_str("34");
pj_strdup(pool, &mv->desc.transport, &STR_RTP_AVP);
attr = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_attr);
attr->name = pj_str("rtpmap");
attr->value = pj_str("34 H263/90000");
mv->attr[mv->attr_count++] = attr;
attr = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_attr);
attr->name = STR_SENDRECV;
mv->attr[mv->attr_count++] = attr;
/* Orginal */
*p_sdp = sdp;
return PJ_SUCCESS;
