Hello, I use the svn trunk of pjsip with the video support. I would like to place a call without video support and for that I implement the following solution. Unfortunately pjsip crashes. 1/ I disable all video codec with /pjsua_vid_codec_set_priority/ function. 2/ To place a call, I use /pjsua_call_make_call/ without option, so I call the function as: pjsua_call_make_call(identifier, uri, NULL, NULL, NULL, &callIdentifier); The stack is: pjsua_call_make_call on_make_call_med_tp_complete pjsip_inv_create_uac pjmedia_sdp_neg_create_w_local_offer pjmedia_sdp_validate Unfortunately, /pjmedia_sdp_validate/ function returns PJMEDIA_SDP_ENOFMT, because pjsip creates a media video sdp line whereas the /fmt_count/ field is zero. I believe the media video sdp line shouldn't be create in this case in /pjsua_media_channel_create_sdp/. What do you think of this ? Thanks in advance for your answer. Regards Samuel PS: it's possible to use /pjsua_call_make_call/, with the option /pjsua_call_setting/ and the /vid_cnt /field defines to zero.
