Question

how to record a media of rtp session into a file? and I search a function-rtpproxy_start_recording() in the rtpproxy module,but how to use it.

Answer 1

To start recording you should just call rtpproxy_start_recording function in your config file as described in RTPproxy module opensips documentation. But you should take in mind that this func could be called only when when new request/reply received:

This function can be used from REQUEST_ROUTE and ONREPLY_ROUTE.

For instance:

route {
  # just forward all in-dialog requests

  if (has_totag()) {
    t_relay();
    exit;
  }

  if (is_method("INVITE")) {
    t_on_reply("MANAGE_INVITE_REPLY");
  }

  t_relay();
}

onreply_route[MANAGE_INVITE_REPLY] {
  if (status=="200") {
    rtpproxy_start_recording();
  } 
}

That's just sketch,rtpproxy managing is omitted for simplification.
