No screenshot.  Post your image on a public share, e.g. Google Drive, DropBox etc. and post a link back here.

Hi,
Without looking at the SDP RFC or Wireshark code I think Wireshark expects a numeral (Dynamic payload) as the first entry in the fmtp. Compare with the audio fmtp:121

Can you provide a capture file?
if (!ws_strtou8(payload_type, NULL, &media_format) || media_format >= SDP_NO_OF_PT) {
                        expert_add_info(pinfo, media_format_item, &ei_sdp_invalid_media_format);
