[Live-devel] [External] Re: Latency increased for low fps source when multiple session created in same server for different source (Renish Tala)

[Renish Tala]

Hi,


My code is working fine with single source but if I add another source then latency is increasing for another source and first source is working fine. we have overridden doGetNextFrame as below.


void LiveSourceWithx264::doGetNextFrame() {
    deliverFrame();
}


Thanks & Regards,
Renish Tala

I'm using the Live555 API for my RTSP server, and have not experienced this issue. I have several sources with varying frame rates between 8 and 30fps running on the same server. I'm triggering Live555 whenever a packet is available from the encoder, and have yet to experience the "not ready for the data yet" error. Here's my DeliverFrame method (CameraFrameSource is a FramedSource), which is called by both the trigger event and the overridden doGetNextFrame method (you DO have an overridden doGetNextFrame method, right?):

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

        if (isCurrentlyAwaitingData ())
        {
                if (_encodedSource->GetFrame (&frameData, &frameSize, &_ulLastFrameSent))
                {
                        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;
                }
        }
}
