I tried to debug rtspsrc and I inserted a break point at the end of
gst_rtsp_connection_receive (cleanup) here is what I get from gdb:
(gdb) p res
$1 = GST_RTSP_EPARSE
(gdb) p timeout
$2 = (GTimeVal *) 0x80d623c
(gdb) p *timeout
$3 = {tv_sec = 20, tv_usec = 0}
(gdb) p message->type
$4 = GST_RTSP_MESSAGE_REQUEST
(gdb) p *conn
$5 = {url = 0xb6d00cb0, fd0 = {fd = 10, idx = 1}, fd1 = {fd = -1, idx = 0},
readfd = 0xb6d01304, writefd = 0xb6d01304, manual_http = 0, tunnelid =
'\000' <repeats 23 times>, tunneled = 0,
  tstate = TUNNEL_STATE_NONE, fdset = 0xb6d01808, ip = 0xb6d01640
"192.168.214.117", read_ahead = 0, initial_buffer = 0x0,
initial_buffer_offset = 0, cseq = 16,
  session_id = "123012", '\000' <repeats 505 times>, timeout = 120, timer =
0xb6d01598, auth_method = GST_RTSP_AUTH_DIGEST, username = 0xb6d03490
"******", passwd = 0xb6d034a0 "******",
  auth_params = 0x80d9088, ctx = {state = 0, save = 0, out = "\000\000",
cout = 0, coutl = 0}, ctxp = 0x0, proxy_host = 0x0, proxy_port = 0}
(gdb) p *message
$7 = {type = GST_RTSP_MESSAGE_REQUEST, type_data = {request = {method =
GST_RTSP_INVALID, uri = 0xb6d1c608 "q\262\265\277@\020\064\026!I", version
= GST_RTSP_VERSION_1_0}, response = {
      code = GST_RTSP_STS_INVALID, reason = 0xb6d1c608
"q\262\265\277@\020\064\026!I",
version = GST_RTSP_VERSION_1_0}, data = {channel = 0 '\000'}}, hdr_fields =
0xb6d1cd80, body = 0x0, body_size = 0}

I see  "reason" in the message structure, could someone tell me what it
means, and more in general has someone any clues of why I got this "Could
not receive message. (Parse error)?"
