[Linphone-developers] segmentation fault receiving RPT AVP stream with m

Subject: [Linphone-developers] segmentation fault receiving RPT AVP stream with mediastreamer2

I’m trying to receive a RTP AVP stream with h264 Payload using mediastreamer2. I constructed a simple graph with two filters (MS_RTP_RECV_ID and MS_FILE_REC_ID) to write the stream to a file. First thing I’m wondering about: oRTP opens two UDP ports: The one I specified with “rtp_session_set_local_addr” and another one which is changing every time I run my program. Why two ports?


Second thing: I’m getting a Segmentation Fault after a few hundred milliseconds when receiving the stream along with loads of messages like this:

“2016-08-04 14:25:12:951 ortp-warning-rtp_putq: Queue is full. Discarding message with ts=<different timestamps>”


According to the backtrace (attached), oRTP calls “rtp_session_rtcp_process_recv” which seems like a function used for RTCP!? I don’t want to use RTCP. Is it even possible to receive a RTP-only stream?
