.TH CURLOPT_INTERLEAVEFUNCTION 3 "19 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
|
|
.SH NAME
|
|
CURLOPT_INTERLEAVEFUNCTION \- callback function for RTSP interleaved data
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
size_t interleave_callback(void *ptr, size_t size, size_t nmemb,
|
|
void *userdata);
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_INTERLEAVEFUNCTION,
|
|
interleave_callback);
|
|
.SH DESCRIPTION
|
|
Pass a pointer to your callback function, which should match the prototype
|
|
shown above.
|
|
|
|
This callback function gets called by libcurl as soon as it has received
|
|
interleaved RTP data. This function gets called for each $ block and therefore
|
|
contains exactly one upper-layer protocol unit (e.g. one RTP packet). Curl
|
|
writes the interleaved header as well as the included data for each call. The
|
|
first byte is always an ASCII dollar sign. The dollar sign is followed by a
|
|
one byte channel identifier and then a 2 byte integer length in network byte
|
|
order. See \fIRFC2326 Section 10.12\fP for more information on how RTP
|
|
interleaving behaves. If unset or set to NULL, curl will use the default write
|
|
function.
|
|
|
|
Interleaved RTP poses some challenges for the client application. Since the
|
|
stream data is sharing the RTSP control connection, it is critical to service
|
|
the RTP in a timely fashion. If the RTP data is not handled quickly,
|
|
subsequent response processing may become unreasonably delayed and the
|
|
connection may close. The application may use \fICURL_RTSPREQ_RECEIVE\fP to
|
|
service RTP data when no requests are desired. If the application makes a
|
|
request, (e.g. \fICURL_RTSPREQ_PAUSE\fP) then the response handler will
|
|
process any pending RTP data before marking the request as finished.
