RE: [Linphone-developers] oRTP MPEG4 video streaming

I've added a new profile to my application, but i've only a warning now.

RTP: Succesfully setup remote peer to 192.168.198.15 port 50208
ortp-warning-rtp_session_recv_with_ts: unable to recv an unsupported payload.

My code (a piece) is:

ortp_init();
   ortp_scheduler_init();

   recvsession=rtp_session_new(RTP_SESSION_RECVONLY);

   if (recvsession  == NULL)
   {
        printf("RTP FATAL: Unable to allocate new session.");
        return -1;
   }
   rtp_session_set_scheduling_mode (recvsession, 1);

   rtp_session_set_blocking_mode (recvsession, 0);


    m_videoMpeg4 = rtp_profile_new("AV profile + MPEG4 Video");
    rtp_profile_set_payload(m_videoMpeg4,0,&payload_type_pcmu8000);
    rtp_profile_set_payload(m_videoMpeg4,1,&payload_type_lpc1016);
    rtp_profile_set_payload(m_videoMpeg4,3,&payload_type_gsm);
    rtp_profile_set_payload(m_videoMpeg4,4,&payload_type_g7231);
    rtp_profile_set_payload(m_videoMpeg4,8,&payload_type_pcma8000);
    rtp_profile_set_payload(m_videoMpeg4,18,&payload_type_g729);
    rtp_profile_set_payload(m_videoMpeg4,31,&payload_type_h261);
    rtp_profile_set_payload(m_videoMpeg4,32,&payload_type_mpv);
    rtp_profile_set_payload(m_videoMpeg4,96,&payload_type_mp4v);

    rtp_session_set_profile(recvsession, m_videoMpeg4);



   rtp_session_set_jitter_compensation (recvsession, 60);

   ret = rtp_session_set_local_addr (
                        recvsession,
                        "192.168.195.16",
                        20000
                        );
   ret = rtp_session_set_remote_addr (
                        recvsession,
                        "192.168.198.13",
                        atoi(serverPort1)
                        );
   if (ret != 0)
   {
        printf("\nRTP: ERROR: Unable to set peer to 192.168.198.15 port %d",atoi(serverPort1));
        return -1;
   }
   else
        printf("\nRTP: Succesfully setup remote peer to 192.168.198.15 port %d",atoi(serverPort1));
   data_from_rtp = (char *) malloc (1500);
   have_more = 1;

   while (have_more)
   {
        printf("\nin while");
        recvd_bytes = rtp_session_recv_with_ts (
                                recvsession,
                                data_from_rtp,
                                1500,
                                timestamp,
                                &have_more);
        printf("\nBytes letti: %d",recvd_bytes);

                if (have_more != 0)
                        printf("\nRTP Warning, have more !");
                 else
                        timestamp += recvd_bytes;

                if (recvd_bytes > 0)
                {
                        printf("\nWriting to file!");
                        n = fwrite(data_from_rtp,sizeof(data_from_rtp),n,outfile);
                        printf("\nBytes scritti: %d",n);
                }
   }

  fclose(outfile);
  free (data_from_rtp);

Is my code wrong?

Thanks

Ah, I ran into the same issue with another Cam. You have to create a new profile:

    m_videoMpeg4 = rtp_profile_new("AV profile + MPEG4 Video");
    rtp_profile_set_payload(m_videoMpeg4,0,&payload_type_pcmu8000);
    rtp_profile_set_payload(m_videoMpeg4,1,&payload_type_lpc1016);
    rtp_profile_set_payload(m_videoMpeg4,3,&payload_type_gsm);
    rtp_profile_set_payload(m_videoMpeg4,4,&payload_type_g7231);
    rtp_profile_set_payload(m_videoMpeg4,8,&payload_type_pcma8000);
    rtp_profile_set_payload(m_videoMpeg4,18,&payload_type_g729);
    rtp_profile_set_payload(m_videoMpeg4,31,&payload_type_h261);
    rtp_profile_set_payload(m_videoMpeg4,32,&payload_type_mpv);
    rtp_profile_set_payload(m_videoMpeg4,96,&payload_type_mp4v);

Beware, the payload type you specify in the last line should match the payload
type actually sent by your cam (use a Etheral capture to check).

Then assign this profile to your session :

    rtp_session_set_profile(s, m_videoMpeg4);
