Any input on this?

Thank you Ross for clarification, its more clear now. Now I am facing
issue that i have separate thread that pushes audio packets for my
device source to stream. I trigger event each time I push packet to
that queue. I noticed that on VLC my audio comes for about a second
and then stops. When I debugged my code I found that I have more than
1000 packets in my audio queue waiting to be streamed by devicesource.
I think what is happening is that whenever I trigger an event and that
event is already happening it ignores it, is it correct? Whats is the
correct way to handle this. I think the audio packets should be
streamed at the same rate as they are being encoded from live source.
Thanks

I am confused as how the event mechanism works in live555. I have a
source that is fed with video and audio frames and I want to trigger
doGetNextFrame() of my custom DeviceSource so that those frames are
streamed using live555. For this I am using
m_eventID =
envir().taskScheduler().createEventTrigger(deliverFrame0);
envir().taskScheduler().triggerEvent(m_eventID, this);
The "this" in the "triggerEvent()" call is wrong, because you should
not be calling "triggerEvent()" from within one of your 'DeviceSource'
class's member functions. "triggerEvent()" should be called from a
*separate thread* - the thread that is doing your encoding. Because
this separate thread is not the LIVE555 thread, then "triggerEvent()"
is the *only* LIVE555 code that it is allowed to be calling.
void MyStreamingDeviceSource::deliverFrame0(void* clientData)
{
((MyStreamingDeviceSource*)clientData)->doGetNextFrame();
}
No, don't do this. "deliverFrame0()" should call "deliverFrame()", as
illustrated in the "DeviceSource" code.
But doGe[Next]tFrame is called when I called
videoSink->startPlaying() too which is not valid for me as I dont
have any data yet to stream.
That's OK. When data later *does* become available, then your separate
'encoder' thread will call "triggerEvent()", and then "deliverFrame()"
will be called.
