CURLOPT_RTSP_TRANSPORT − set RTSP Transport: header
curl_easy_setopt(CURL *handle, CURLOPT_RTSP_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.
The application does not have to keep the string around after setting this option.
CURL *curl =
curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/");
curl_easy_setopt(curl, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_SETUP);
ret = curl_easy_perform(curl);
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.
