CURLOPT_RTSP_TRANSPORT explained

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 res;
    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=4588-4589");
    res = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

History

Availability

Added in curl 7.20.0
