<blockquote type="cite" cite>I have a question about the openRTSP. In
the end of the function startPlayingStreams, there is :<br>
// Watch for incoming packets (if desired):<br>
checkForPacketArrival(NULL);<br>
checkInterPacketGaps(NULL);<br>
<br>
My question is whether the video or audio
packets haved been rececived here.</blockquote>
<div><br></div>
<div>The first time that these functions are called, no RTP (audio or
video) packets will have been received yet (because the event loop
hasn't yet started; see below). Notice, though, that each of
these functions - at the very end of their code - reschedules another
call to itself, from the event loop, after a short delay. I.e.,
each of these functions gets called periodically.</div>

<blockquote type="cite" cite> If the packets are received here,
then what is<br>
the difference between the role of the function
startPlayingStreams and the function<b>
taskScheduler().doEventLoop()</b></blockquote>
<blockquote type="cite" cite>in reveiving the packets.</blockquote>
<div><br></div>
<div>No incoming packets actually get handled until
"doEventLoop()" is called (because the arrival of each
incoming packet is handled as an 'event' from within the event
loop).</div>
