[Live-devel] ] isCurrentlyAwaitingData

[Weber, Patrick]

When determining if you should deliver a frame, you need to check if Live555 is waiting for one. Something like this in your FramedSource subclass:

		//====================================================================
		// Deliver a frame from the RTSPSource object.
		//====================================================================
		void CameraFramedSource::DeliverFrame ()
		{
			byte *frameData;
			unsigned frameSize;

			if (isCurrentlyAwaitingData ())
			{
				if (_encodedSource->GetFrame (&frameData, &frameSize, &_ulLastFrameSent))
				{
					try
					{
						if (frameSize > 0 && frameData != nullptr)
						{
							if (frameSize > fMaxSize)
							{
								fFrameSize = fMaxSize;
								fNumTruncatedBytes = frameSize - fMaxSize;
							}
							else
							{
								fFrameSize = frameSize;
								fNumTruncatedBytes = 0;
							}
							SetPresentationTime (_ulLastFrameSent);
							if (SafeMemCopy (fTo, frameData, frameSize))
								FramedSource::afterGetting (this);
						}
						_encodedSource->ReleaseFrame ();
						++_ulFramesDelivered;
					}
					catch (...) { }
				}
			}
