You can try upping the speed with set_hz()
initialized in FlightGear\src\Network\jpg-httpd.cxx
bool FGJpegHttpd::open() {
if ( is_enabled() ) {
SG_LOG( SG_IO, SG_ALERT, "This shouldn't happen, but the channel "
<< "is already in use, ignoring" );
return false;
}
imageServer = new HttpdImageServer( port );
set_hz( 5 ); // default to processing requests @ 5Hz
set_enabled( true );
return true;
}
But .....
Probably best to use the jpeg-httpd as a prototype for a raw avi file
writer. i.e you probably want the tr stuff bit you don't really need it
There is some simple portable GL to AVI code here
