Hi,
   i am writing a RTSP client program. I am using live555 as a RTSP server.
When i am sending a SETUP request the i am getting a response with code 400
(Bad request). Can anyone help me with this, the code looks like this:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include <curl/curl.h>

static size_t rtp_write(void *ptr, size_t size, size_t nmemb, void *stream){
  printf("Size is: %d\n",size);
  printf("Nmemb is: %d\n",nmemb);
  return size*nmemb;
}

int main(int argc, char *argv[])
{
  CURL *csession;
  CURLcode res;
  struct curl_slist *custom_msg = NULL;

  char URL[256];
  char request[256];
  long rc;
  int port = 48000;
  FILE * protofile = NULL;
  protofile = fopen("Dump","wb");
  if (argc < 2)
  {
      fprintf (stderr, "ERROR: enter a valid URL\n");
      return -1;
  }

  csession = curl_easy_init();

  if (csession == NULL)
      return -1;
  printf("%s\n", argv[1]);
  sprintf (URL, "%s", argv[1]);

  curl_easy_setopt(csession, CURLOPT_URL, URL);
  curl_easy_setopt(csession, CURLOPT_RTSP_STREAM_URI, URL);
  curl_easy_setopt(csession, CURLOPT_FOLLOWLOCATION, 1);
  curl_easy_setopt(csession, CURLOPT_HEADER, 1);
  curl_easy_setopt(csession, CURLOPT_INTERLEAVEFUNCTION, rtp_write);
  curl_easy_setopt(csession, CURLOPT_INTERLEAVEDATA, protofile);
  //curl_easy_setopt(csession, CURLOPT_VERBOSE, 1);

  /** retrieve OPTIONS */
  curl_easy_setopt(csession, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_OPTIONS);
  res = curl_easy_perform(csession);
  res = curl_easy_getinfo(csession, CURLINFO_RESPONSE_CODE, &rc);
  if((res == CURLE_OK) && rc)
  {
      fprintf(stderr, "OPTIONS Response Code: %ld\n\n", rc);
  }
  else
      return -1;

  /** send DESCRIBE */

application/rtsl, application/sdp");

  }
  else
      return -1;

  /** send SETUP */
  sprintf (request, "RTP/AVP;unicast;client_port=%
d", port);
  curl_easy_setopt(csession, CURLOPT_RTSP_TRANSPORT, request);
  curl_easy_setopt(csession, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_SETUP);
  res = curl_easy_perform(csession);
  res = curl_easy_getinfo(csession, CURLINFO_RESPONSE_CODE, &rc);

  if((res == CURLE_OK) && rc)
  {
      fprintf(stderr, "SETUP Response Code: %ld\n\n", rc);
  }
  else
      return -1;

  /** send PLAY */
  curl_easy_setopt(csession, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_PLAY);

  if((res == CURLE_OK && rc))
  {
      fprintf(stderr, "GET_PARAMETER Response Code: %ld\n\n", rc);
  }
  else
      return -1;
  */
  /** send TEARDOWN */
  curl_easy_setopt(csession, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_TEARDOWN);
  res = curl_easy_perform(csession);

  res = curl_easy_getinfo(csession, CURLINFO_RESPONSE_CODE, &rc);

  curl_easy_cleanup(csession);
  fclose(protofile);
