NAME

CURLOPT_RTSP_TRANSPORT - RTSP Transport: header

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_TRANSPORT,
                          char *transport);

DESCRIPTION

Pass a char pointer to tell libcurl what to pass for the Transport: header for this RTSP session. This is mainly a convenience method to avoid needing to set a custom Transport: header for every SETUP request. The application must set a Transport: header before issuing a SETUP request.

The application does not have to keep the string around after setting this option.

DEFAULT

NULL

PROTOCOLS

This functionality affects rtsp only

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/");
    curl_easy_setopt(curl, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_SETUP);
    curl_easy_setopt(curl, CURLOPT_RTSP_TRANSPORT,
                     "RTP/AVP;unicast;client_port=458-4589");
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

HISTORY

CURL_RTSPREQ_* enums became long types in 8.13.0, prior to this version a long cast was necessary when passed to curl_easy_setopt(3).

AVAILABILITY

Added in curl 7.20.0

RETURN VALUE

curl_easy_setopt(3) returns a CURLcode indicating success or error.

CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
