CURLOPT_RTSP_REQUEST(3) Library Functions Manual CURLOPT_RTSP_REQUEST(3) NAME CURLOPT_RTSP_REQUEST - 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 follow- ing 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 appli- cation 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 applica- tion should note what formats it understands in the 'Accept:' header. Unless set manually, libcurl automatically adds in 'Ac- cept: application/sdp'. Time-condition headers are added to De- scribe requests if the CURLOPT_TIMECONDITION(3) option is used. (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_PARAME- TER 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 CURLOPT_RTSP_TRANSPORT(3) option prior to calling setup. If no session ID is currently set with CUR- LOPT_RTSP_SESSION_ID(3), libcurl extracts and uses 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 CURLOPT_RANGE(3) op- tion to modify the playback time (e.g. npt=10-15). CURL_RTSPREQ_PAUSE Send a Pause command to the server. Use the CURLOPT_RANGE(3) op- tion 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 con- nection 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 adds 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 wish- ing 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 uses a *Con- tent-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 CURLOPT_UPLOAD(3) with CUR- LOPT_READDATA(3) like an HTTP PUT, or it may use CURLOPT_POST- FIELDS(3) like an HTTP POST. No chunked transfers are allowed, so the application must set the CURLOPT_INFILESIZE(3) in the former and 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 CUR- LOPT_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 returns after processing one read buffer of data in order to give the application a chance to run. DEFAULT PROTOCOLS This functionality affects rtsp only EXAMPLE int main(void) { CURL *curl = curl_easy_init(); if(curl) { CURLcode res; curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/"); /* ask for options */ curl_easy_setopt(curl, CURLOPT_RTSP_REQUEST, CURL_RTSPREQ_OPTIONS); res = curl_easy_perform(curl); curl_easy_cleanup(curl); } } AVAILABILITY Added in curl 7.20.0 RETURN VALUE curl_easy_setopt(3) returns a CURLcode indicating success or error. CURLE_OK (0) means everything was OK, non-zero means an error occurred, see libcurl-errors(3).
