NAME
       CURLOPT_RTSP_REQUEST - specify RTSP request

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_REQUEST, long
       request);

DESCRIPTION
       Tell libcurl what kind of RTSP request to make. Pass one of the
       following RTSP enum values as a long in the request argument. Unless
       noted otherwise, commands require the Session ID to be initialized.

       CURL_RTSPREQ_OPTIONS
              Used to retrieve the available methods of the server. The
              application is responsible for parsing and obeying the response.
              The session ID is not needed for this method.

       CURL_RTSPREQ_DESCRIBE
              Used to get the low level description of a stream. The
              application should note what formats it understands in the
              'Accept:' header. Unless set manually, libcurl will
              automatically fill in 'Accept: application/sdp'.  Time-condition
              headers will be added to Describe requests if the
              _TIMECONDITION&section=3">CURLOPT_TIMECONDITION(3) option is active. (The session ID is
              not needed for this method)

       CURL_RTSPREQ_ANNOUNCE
              When sent by a client, this method changes the description of
              the session. For example, if a client is using the server to
              record a meeting, the client can use Announce to inform the
              server of all the meta-information about the session.  ANNOUNCE
              acts like an HTTP PUT or POST just like
              CURL_RTSPREQ_SET_PARAMETER

       CURL_RTSPREQ_SETUP
              Setup is used to initialize the transport layer for the session.
              The application must set the desired Transport options for a
              session by using the _RTSP_TRANSPORT&section=3">CURLOPT_RTSP_TRANSPORT(3) option prior to
              calling setup. If no session ID is currently set with
              _RTSP_SESSION_ID&section=3">CURLOPT_RTSP_SESSION_ID(3), libcurl will extract and use the
              session ID in the response to this request. The session ID is
              not needed for this method.

       CURL_RTSPREQ_PLAY
              Send a Play command to the server. Use the _RANGE&section=3">CURLOPT_RANGE(3)
              option to modify the playback time (e.g. 'npt=10-15').

       CURL_RTSPREQ_PAUSE
              Send a Pause command to the server. Use the _RANGE&section=3">CURLOPT_RANGE(3)
              option with a single value to indicate when the stream should be
              halted. (e.g. npt='25')

       CURL_RTSPREQ_TEARDOWN
              This command terminates an RTSP session. Simply closing a
              connection does not terminate the RTSP session since it is valid
              to control an RTSP session over different connections.

       CURL_RTSPREQ_GET_PARAMETER
              Retrieve a parameter from the server. By default, libcurl will
              automatically include a Content-Type: text/parameters header on
              all non-empty requests unless a custom one is set. GET_PARAMETER
              acts just like an HTTP PUT or POST (see
              CURL_RTSPREQ_SET_PARAMETER).  Applications wishing to send a
              heartbeat message (e.g. in the presence of a server-specified
              timeout) should send use an empty GET_PARAMETER request.

       CURL_RTSPREQ_SET_PARAMETER
              Set a parameter on the server. By default, libcurl will
              automatically include a Content-Type: text/parameters header
              unless a custom one is set. The interaction with SET_PARAMETER
              is much like an HTTP PUT or POST. An application may either use
              _UPLOAD&section=3">CURLOPT_UPLOAD(3) with _READDATA&section=3">CURLOPT_READDATA(3) like a HTTP PUT, or
              it may use _POSTFIELDS&section=3">CURLOPT_POSTFIELDS(3) like an HTTP POST. No chunked
              transfers are allowed, so the application must set the
              _INFILESIZE&section=3">CURLOPT_INFILESIZE(3) in the former and _POSTFIELDSIZE&section=3">CURLOPT_POSTFIELDSIZE(3)
              in the latter. Also, there is no use of multi-part POSTs within
              RTSP.

       CURL_RTSPREQ_RECORD
              Used to tell the server to record a session. Use the
              _RANGE&section=3">CURLOPT_RANGE(3) option to modify the record time.

       CURL_RTSPREQ_RECEIVE
              This is a special request because it does not send any data to
              the server. The application may call this function in order to
              receive interleaved RTP data. It will return after processing
              one read buffer of data in order to give the application a
              chance to run.
