Set rtsp transport: header
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_TRANSPORT, char *transport);
Pass a char * 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.
Added in 7.20.0
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
