Hi again,

 

could anyone please give an answer? If mediastreamer2 is suitable, we consider to buy the commercial license.

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

 

Hey,

 

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?

 

Kind Regards
