# NAME
CURLOPT_RTSP_TRANSPORT - RTSP Transport: header
# SYNOPSIS
~~~c
#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
RTSP
# EXAMPLE
~~~c
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);
}
}
~~~
