[Linphone-developers] Streaming Rtp flow on local sound card

[daniele elia]

I have made a simple program to reproduce rtp traffic on sound cardo on linux environment. When I run the program not hear anything. Where I'm wrong? It's possible put all udp traffic of all ports and not only traffic declared on defined rtp port, how can I do?

Source code:

#include <stdio.h>
#include <stdlib.h>
#include "mscommon.h"
#include "mediastream.h"
//Not useful - Start
#include "msrtp.h"
#include "mstonedetector.h"
#include "logging.h"
#include "rtpsession.h"
#include "sessionset.h"
#include "payloadtype.h"
#include "rtpprofile.h"
//Stop

#define PCMA8_PAYLOAD_TYPE 8

#define RTP_PORT 15176
#define RTCP_PORT 15177
#define _IP "127.0.0.1"

int main(void) {

    bool isAudioStreamEnabled = false;

    //Init media stream and ortp
    ms_init();
    ms_filter_enable_statistics(TRUE);
    ortp_init();

    ortp_scheduler_init();

    ortp_set_log_level_mask(ORTP_MESSAGE|ORTP_WARNING|ORTP_ERROR);



    RtpSession * rtpSession;
    rtpsession = rtp_session_new(RTP_SESSION_RECVONLY);

    rtp_session_set_scheduling_mode(rtpSession, 1);

    rtp_session_set_blocking_mode(rtpSession, 0);
    

    rtp_session_adaptive_jitter_compensation_enabled(rtpSession);

    rtp_session_set_local_addr(rtpSession, "127.0.0.1", -1, -1);

    rtp_session_set_payload_type(rtpSession, 8);

    RtpProfile * profile = rtp_profile_new("default profile");
    rtp_profile_set_payload (profile,PCMA8_PAYLOAD_TYPE,&payload_type_pcma8000);

    rtp_session_set_profile(rtpSession, profile);

    rtp_session_set_recv_profile(rtpSession, profile);

    
    MSSndCard * defaultSoundCard = ms_snd_card_manager_get_default_card(ms_snd_card_manager_get ());


    AudioStream * audioStream = audio_stream_new(RTP_PORT, RTCP_PORT, false);
  

    audio_stream_start_full(audioStream, profile, _IP, RTP_PORT, _IP, RTCP_PORT, PCMA8_PAYLOAD_TYPE, 50, NULL, NULL, defaultSoundCard, NULL, false);
    

    sleep(10);

    rtp_session_destroy(rtpSession);

    ms_exit();

    ortp_exit();

    ortp_global_stats_display();

    return EXIT_SUCCESS;
}

Thanks in advice.

Regards
