I did a little debug, and discovered my OnDemandServerMediaSubsession 
subclass gets created twice when a stream is requested. It consequently 
creates two H263plusVideoRTPSink  instances. May this be the the problem?

Here it is a snippet of my debug results:

Play this stream using the URL "rtsp://192.168.1.77/video"
(stream request by VLC)
Started a new EncH263plusVideoFileServerMediaSubsession
Done
Creating new sink
Started a new EncH263plusVideoFileServerMediaSubsession
Done
Creating new sink
(creates two EncH263plusVideoFileServerMediaSubsession and two sinks)
H263FramedSource: Calling deliverFrame()
(starts delivering frames)
Frame 0 long 5302

I create the media session etc like that in the main():

ServerMediaSession* sms
      = ServerMediaSession::createNew(*env, streamName, streamName,
                      descriptionString);
   
    EncH263plusVideoFileServerMediaSubsession* mss = 
EncH263plusVideoFileServerMediaSubsession::createNew(*env, inputSink, 
reuseFirstSource);
  
    sms->addSubsession(mss);
    rtspServer->addServerMediaSession(sms);
    announceStream(rtspServer, sms, streamName, inputSink);

Am I doing something wrong?

Regards,

Cristiano.
