Hi,
You shouldn't put the H.263 codec in the audio media line. To see
"m=video ..." you will need to add the video media line to the SDP,
e.g:
sdp->media[sdp->media_count++] = mvideo;
then add media format(s) to video media, e.g: H.263 (with static
payload type=34) :
mvideo->desc.fmt_count = 0;
m->desc.fmt[m->desc.fmt_count++] = pj_str("34");
Regards,
nanang
