Hello,
I want sofsip cli works with PCMA instead of PCMU. How to modify it ?
I modified ssc_media_gst.c

  self->sm_pt = 0; /* PT=0 => PCMU */
  /* step: initialize the PT<->caps hash table */
  pt_caps = gst_caps_new_simple ("application/x-rtp",
     "clock-rate", G_TYPE_INT, 8000,
     "encoding-name", G_TYPE_STRING, PCMU 
     NULL);
  
  /* step: describe capabilities in SDP terms */
  /* support only G711/PCMA */
  caps_sdp_str = su_strcat(home, caps_sdp_str, 
      "v=0\r\n"
      "m=audio 0 RTP/AVP 0\r\n"
      "a=rtpmap:0 PCMU/8000\r\n");
  *dest = strdup(caps_sdp_str);
  su_free(home, caps_sdp_str);
->
  self->sm_pt = 0; /* PT=0 => PCMA */
  /* step: initialize the PT<->caps hash table */
  pt_caps = gst_caps_new_simple ("application/x-rtp",
     "clock-rate", G_TYPE_INT, 8000,
     "encoding-name", G_TYPE_STRING, "PCMA",
     NULL);
  
  /* step: describe capabilities in SDP terms */
  /* support only G711/PCMA */
  caps_sdp_str = su_strcat(home, caps_sdp_str, 
      "v=0\r\n"
      "m=audio 0 RTP/AVP 0\r\n"
      "a=rtpmap:0 PCMA/8000\r\n");
  *dest = strdup(caps_sdp_str);
  su_free(home, caps_sdp_str);
 
and 
gsdp_codec_factories_t *factories = gsdp_codec_factories_create("PCMU");
->
gsdp_codec_factories_t *factories = gsdp_codec_factories_create("PCMA");
It does not work (FAILED with 501 Not Implemented Yet)
I tryed
->
  self->sm_pt = 8; /* PT=0 => PCMA */
  /* step: initialize the PT<->caps hash table */
  pt_caps = gst_caps_new_simple ("application/x-rtp",
     "clock-rate", G_TYPE_INT, 8000,
     "encoding-name", G_TYPE_STRING, "PCMA",
     NULL);
  
  /* step: describe capabilities in SDP terms */
  /* support only G711/PCMA */
  caps_sdp_str = su_strcat(home, caps_sdp_str, 
      "v=0\r\n"
      "m=audio 0 RTP/AVP 0\r\n"
      "a=rtpmap:8 PCMA/8000\r\n");
  *dest = strdup(caps_sdp_str);
  su_free(home, caps_sdp_str);
It does not work (FAILED with 501 Not Implemented Yet)
Does anyone have an idea ?
Thank you,
Fabien
