Pass one of the following RTSP +enum values as a long in the \fIrequest\fP argument. Unless noted otherwise, +commands require the Session ID to be initialized. +.IP 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. +.IP CURL_RTSPREQ_DESCRIBE +Used to get the low level description of a stream. The application should note +what formats it understands in the \fI'Accept:'\fP header. Unless set +manually, libcurl will automatically fill in \fI'Accept: application/sdp'\fP. +Time-condition headers will be added to Describe requests if the +\fICURLOPT_TIMECONDITION(3)\fP option is active. \fB(The session ID is not +needed for this method)\fP +.IP 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 +\fICURL_RTSPREQ_SET_PARAMETER\fP +.IP 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 +\fICURLOPT_RTSP_TRANSPORT(3)\fP option prior to calling setup. If no session +ID is currently set with \fICURLOPT_RTSP_SESSION_ID(3)\fP, libcurl will +extract and use the session ID in the response to this request. The session ID +is not needed for this method. +.IP CURL_RTSPREQ_PLAY +Send a Play command to the server. Use the \fICURLOPT_RANGE(3)\fP option to +modify the playback time (e.g. 'npt=10-15'). +.IP CURL_RTSPREQ_PAUSE +Send a Pause command to the server. Use the \fICURLOPT_RANGE(3)\fP option with +a single value to indicate when the stream should be halted. (e.g. npt='25') +.IP 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. +.IP CURL_RTSPREQ_GET_PARAMETER +Retrieve a parameter from the server. By default, libcurl will automatically +include a \fIContent-Type: text/parameters\fP header on all non-empty requests +unless a custom one is set. GET_PARAMETER acts just like an HTTP PUT or POST +(see \fICURL_RTSPREQ_SET_PARAMETER\fP). +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. +.IP CURL_RTSPREQ_SET_PARAMETER +Set a parameter on the server. By default, libcurl will automatically include +a \fIContent-Type: text/parameters\fP 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 \fICURLOPT_UPLOAD(3)\fP with \fICURLOPT_READDATA(3)\fP like a +HTTP PUT, or it may use \fICURLOPT_POSTFIELDS(3)\fP like an HTTP POST. No +chunked transfers are allowed, so the application must set the +\fICURLOPT_INFILESIZE(3)\fP in the former and \fICURLOPT_POSTFIELDSIZE(3)\fP +in the latter. Also, there is no use of multi-part POSTs within RTSP. +.IP CURL_RTSPREQ_RECORD +Used to tell the server to record a session. Use the \fICURLOPT_RANGE(3)\fP +option to modify the record time. +.IP 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. +.SH DEFAULT +.SH PROTOCOLS +RTSP +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/"); + /* ask for options! */ + curl_easy_setopt(curl, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_OPTIONS); + ret = curl_easy_perform(curl); + curl_easy_cleanup(curl); +} +.fi +.SH AVAILABILITY +Added in 7.20.0 +.SH RETURN VALUE +Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not. +.SH "SEE ALSO" +.BR CURLOPT_RTSP_SESSION_ID "(3), " CURLOPT_RTSP_STREAM_URI "(3), " |
