Uhm, I'm having an hard time subclassing "H263plusVideoFileServerMediaSubsession".
I just added this code:

class EncH263plusVideoFileServerMediaSubsession: public H263plusVideoFileServerMediaSubsession
{
    
private:
    
   FramedSource* createNewStreamSource(unsigned clientSessionId, unsigned& estBitrate);
    
};

FramedSource* EncH263plusVideoFileServerMediaSubsession::createNewStreamSource(unsigned clientSessionId, unsigned& estBitrate)
{
        std::cout << "Started a new Stream Source" << std::endl;

	/* Code to start the encoder thread */

        return H263plusVideoFileServerMediaSubsession::createNewStreamSource(clientSessionId, estBitrate);
}

And i get these errors:
 
~/develop/lib/live-debug/liveMedia/include/H263plusVideoFileServerMediaSubsession.hh: In member function ‘virtual FramedSource* EncH263plusVideoFileServerMediaSubsession::createNewStreamSource(unsigned int, unsigned int&)’:

rtspServer.cpp: At global scope:

Complaining that the destructor of H263plusVideoFileServerMediaSubsession is private (and indeed it is).
If I try to override the destructor in my class, I get similar errors.

Where am I doing wrong? Can you point me to some sample code where it is done right?

Thanks,
