[Live-devel] The total received frame size exceeds the client's buffer size

[Tilouche Khaled]

                        Hi Ross,
 
 
 I have been trying to play with the parameter maxSize but i couldnt notice any changes in the behavour of the system .
 unsigned OutPacketBuffer::maxSize
  I would like to know if there some fondamental changes i have to bring to the code supporting  streams of type VOD to support in an  efficient way live streams coming from a streamer device .
  I am surprised  to see that my relay is working perfectly when i use VOD ,even if i notice some lost packets but it jails when it is about to get the streams from  LIVE video source.
  some times i can get 1 second of live stream then my client says that he is not receiving a stream for more then 10 sec and switches into TCP wich is not my purpose to make it running on that protocol.
  Do you see please any other parameters you think they are important to adapt it to support live streams or to parametrize it  in a way to make it run on one device or the other?
  Thank a lot in advance for your precious advices.
  Sincerely.

   as we see the error show up in the class MultiFramedRTPSource in fact it is my inputSource of type FramedSource used for my server.
   **************************************************************************
  « MultiFramedRTPSource::doGetNextFrame1(): The total received frame size exceeds the client's buffer size (156). 1280 bytes of trailing data will be dropped! »
  
 
  
if (fNumTruncatedBytes > 0) {
        envir() &l!
 t;<
 "MultiFramedRTPSource::doGetNextFrame1(): 
The total received frame size exceeds the client's buffer size ("
                << fSavedMaxSize << ").  "
                << fNumTruncatedBytes << 
" bytes of trailing data will be dropped!\n";

}due to this peace of code
****************************************************************************
  Since am developing a relay so am supposed to get the data from the streamer device and then serving it again into another machine.
   So basicly to do so am using the ServerMediaSession and  the OnDemandServerMediaSubsession
  for sure the inputSource is filled up with the FramedSource coming from the MediaSession class
  fReadSource = fRTPSource
 
  
   = MPEG4ESVideoRTPSource::createNew(env(), fRTPSocket,
    fRTPPayloadFormat,
    fRTPTimestampFrequency);
  So as you see there is no FileSink receiver in my software structure the sink i am using is the one used in that serving class RTPSink created using the method
  
     
RTPSink * MPEG4ESVideoServerMediaSubsession::createNewRTPSink(Groupsock* rtpGroupsock, unsigned char rtpPayloadTypeIfDynamic) {
  return MPEG4ESVideoRTPSink::createNew(envir(), rtpGroupsock, rtpPayloadTypeIfDynamic);
}
MPEG4ESVideoServerMediaSubsession is  designed in the same way then 
MPEG4VideoFileServerMediaSubsession except it is not supporting File
 but live FramedSources.
Still now the RTPSink is of type MediaSink and contain a parameter called
 maxSize
unsigned OutPacketBuffer::maxSize = 60000; !
 // by default
Infact  i suspect it is the origin of troubles.
is it the parameter am supposed to change? Knowing i dont use any other
types of sinks in my system cause i don wanna put my stream into a file since am 
streaming it live.

I ve tryed to increase it a bit nothing happens...
still getting the same troubles.

could you please help me to get a higher client buffer in my case .

Thanks a lot for your help.
