Hi,
I’m using PJSIP version 2.6 and tried to check if the SSRC has changed of the stream. But the RTP status flag badssrc was never set, because the status and all prev. set flags are overridden by calling the function pjmedia_rtp_seq_update() in pjmedia_rtp_session_update2(). I suppose this behavior isn’t intended.
I fixed it with the attached patch.
br, Karl
