<font size="2" face="Verdana">I'm sorry! I have read FAQ ,But I do not think it is simple just like the reference in the FAQ. The applications with live library are event-driven,after calling <em>someSinkObject</em>->startPlaying() ,it will enter into an event loop (TaskScheduler::doEventLoop()). That is just said that now the applicatons will be in the "live library" event until it return.But at the same time on transmiting a RTP packet,I need to capture a frame into the buffers from the live souce(e.g,such like a webcamera).Does it need mutithread programming? Is there any example can be used for reference in this case?</font><p>
