Hi Fedot, First, a sample (pseudo code) of the usage of pjmedia_codec_mgr_set_default_param()/pjsua_vid_codec_set_param() can be seen in http://www.pjsip.org/pjmedia/docs/html/group__PJMED__IPP__CODEC.htm (note: actually it's for audio codecs, but should be similar). To configure profile-level-id in the application should be straightforward, e.g: == ... param.setting.dec_fmtp.param[N].name = pj_str("profile-level-id"); param.setting.dec_fmtp.param[N].val = pj_str("...."); ... pjmedia_codec_mgr_set_default_param(); == Again, we'd recommend to reconfigure codec params (bitrate, framerate, sdp fmtp, etc) using this API instead of changing the library code, this is for your own sake :), e.g: avoid complexity of conflict-resolving/re-patching when updating pjsip version. About quality on the screen shots, it seems to be packet loss issue. Well, when I mentioned about increasing bitrate, I thought the problem was picture sharpness. Note that increasing bitrate may increase the packet loss rate. So perhaps try to re-adjust the bitrate (decrease it this time:) until achieving acceptable balance of packet loss rate & picture sharpness. Further potential solution will be find a lower (and acceptable ofc) video resolution in the sender, so bitrate can be lowered (to minimize packet loss).
