[Live-devel] RTSP Server suddenly stops streaming

[Tiago Fonseca]

I did the tests you suggested and it seems that the problem is on my Server, specifically when streaming h264.

When I run my Server with testRTSPClient, no matter which encoder, after a minute or so it freezes indefinitely.
When I run my Server streaming in FMPG4 and vlc, I'm able to stream forever.
If I change my encoder to h264, the stream shuts down after a while.
(in this case, using wire shark I got a TEARDOWN message...)

I'm receiving my frames from ffmpeg and depending on the encoder used, I use H264VideoStreamFramer/MPEG4VideoStreamFramer and H264VideoRTPSink/MPEG4ESVideoRTPSink.
My FramedSource::deliverFrame() is like this:

void FramedSource::deliverFrame()
{
	if (!isCurrentlyAwaitingData())
		return;
	// Pop frame from Queue
	//...

	// TimeStamp
	gettimeofday(&fPresentationTime, NULL);

	assert(mediaSample->PayloadSize != NULL);
	unsigned int trancate = 0;
	// Frame size and truncate
	if (myFrameSize> fMaxSize) {
		fFrameSize = fMaxSize;
		fNumTruncatedBytes = myFrameSize - fMaxSize;
	}
	else {
		fFrameSize = myFrameSize;
		fNumTruncatedBytes = 0;
	}
	// Deliver the data
	pin_ptr<Byte> d = &myFrame;
	memmove(fTo, d, fFrameSize);

	nextTask() = envir().taskScheduler().scheduleDelayedTask(50000, (TaskFunc*)FramedSource::afterGetting, this);
	return;
}

Hi all,

For the last month, I have been reading about live555 and going through as much examples as I can.
With all the information I was able to get, I manage to make my own RTSP Server and Client.

My RTSP Client runs perfectly and non-stop days and days but there's something about my RTSP Server.
My server starts streaming and everything runs smoothly but sooner or later stops streaming, sometimes after 2 hours or 2 minutes.

Is there anything that I might be doing wrong or missing that may be cause this behavior?
At this point any tips or pointers are a huge help because I really don't know where to look.

Best Regards,
Tiago Fonseca

I don?t know, because you haven?t said very much about your client and (especially) your server.

However, I suggest that you test against the supplied ?testRTSPClient? and ?LIVE555 Media Server? applications; i.e.:
	1/ Check whether ?testRTSPClient? works OK with ?LIVE555 Media Server?
	2/ Check whether your client works with ?LIVE555 Media Server?
	3/ Check whether ?testRTSPClient? works OK with your server.

These tests should tell you where your problem lies:
	- With your network (if 1/ fails)
	- With your client (if 2/ fails)
	- With your server (if 3/ fails).
