Hi guys, thanks for all your help. Just for your information, I solved
it like this, and it works perfect for me, just wondering if there are
more elegant solutions, though.

Derived my own specialised taskscheduler from BasicTaskScheduler wich
implements its event loop like this

void
NucleusTaskScheduler::doEventLoop( char * watchVariable, unsigned
maxDelay )
{
    //
    // Schedule the command handler before actually starting up the
eventLoop
    //
    TaskFunc * taskfunc = reinterpret_cast< TaskFunc *
>( &NucleusTaskScheduler::sCommandHandler );
    m_commandhandler = scheduleDelayedTask( 0, taskfunc, this );

    while (1) {
        if (watchVariable != NULL && *watchVariable != 0) break;
        SingleStep( maxDelay );
    }

    unscheduleDelayedTask( m_commandhandler );
}

In addition, I added a thread safe command queue (an
ACE_Activation_Queue, for those who are familiar with ACE) which the
handler checks and empties every time it is scheduled. Now I can send
asynchronous requests from any thread to start/stop streaming without
leaving Live555's event loop and with guarantees that things are
scheduled when they should.
