Iam running the JMF client at B Side
If i send the video packets from JMF client using Audio port(50484).
from B side its transmitting? and its receiving at A side.
i need to check video port is opened or not at server side.
So iam sending the video packets from JMF client? using video port (50486).
from B side its transmitting, but from A side its not receiving.
For opening video port i followed the code in endpoint.c
sdp->media_count = 2;
??? mVideo = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_media);
??? sdp->media[1] = mVideo;
??? /* Standard media info: */
??? pj_strdup(pool, &mVideo->desc.media, &STR_VIDEO);
??? mVideo->desc.port = pj_sockaddr_get_port(addr0)+2;
??? mVideo->desc.port_count = 1;
??? pj_strdup (pool, &mVideo->desc.transport, &STR_RTP_AVP);
??? /* Init media line and attribute list. */
??? mVideo->desc.fmt_count = 0;
??? mVideo->attr_count = 0;
??? {
??? ??? pjmedia_sdp_rtpmap rtpmap;
??? ??? pjmedia_sdp_attr *attr;
??? ??? pj_str_t *fmt;
??? ??? ???
???
??? fmt = &mVideo->desc.fmt[mVideo->desc.fmt_count++];
??? ??? fmt->ptr = (char*) pj_pool_alloc(pool, 8);
??? ??? fmt->slen = pj_utoa(34, fmt->ptr);
??? ??? rtpmap.pt = *fmt;
??? ??? rtpmap.enc_name = pj_str("H263");
??? ??? rtpmap.clock_rate = 90000;
??? ???
rtpmap.param.slen = 0;
??? ???
??? ??? pjmedia_sdp_rtpmap_to_attr(pool, &rtpmap, &attr);
??? ??? mVideo->attr[mVideo->attr_count++] = attr;
??? }
??? /* Add send receive attribute. */
??? attr = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_attr);
???
attr->name = STR_SENDRECV;
??? mVideo->attr[mVideo->attr_count++] = attr;
please help me,and guide me where i made mistake.
regards
Rams
