[Live-devel] RTP over TCP with iPhone

[Dmitrij Velkin]

Hi Ross,

I followed your advice and start to implement with openRTSP. I  need data in buffer and not in file and so i wrote little class to subclass MediaSink:

class MyMediaSink:public MediaSink
{
    public:
        MyMediaSink(UsageEnvironment &env):MediaSink(env){buffer = new uint8_t();}
        virtual ~MyMediaSink(){}
    protected:
        Boolean continuePlaying(){/*CODE will come soon*/ return true;}
    private:
        uint8_t *buffer;
};

After that I invoke my Class in setupStreams()-funktion:

void setupStreams()
{
    static MediaSubsessionIterator* setupIter = NULL;
    if (setupIter == NULL) setupIter = new MediaSubsessionIterator(*session);
    while ((subsession = setupIter->next()) != NULL)
    {
        // We have another subsession left to set up:
        if (subsession->clientPortNum() == 0) continue; // port # was not set

        setupSubsession(subsession, streamUsingTCP, continueAfterSETUP);
//---------------------
        MyMediaSink *ms = new MyMediaSink(*env);
        ms->startPlaying(*(subsession->readSource()), subsessionAfterPlaying, subsession);
//---------------------        

	return;
    }
.
.
.
.
}
I know there are leaks and the implementation of MyMediaSink is not complete, but I can see that I have the same Problem as with my App.

Thank you in advance!

Dmitrij
