[Live-devel] how to implement env->taskScheduler().doEventLoop() by while(!signal)

[freegnu]

hi all, i want to read the PS from a circular buffer(which get from encode), and the transfers it by testMPEG4VideoStream,  so i want to explant  testMPEG4VideoStream
but the testMPEG4VideoStream it get the media PS from a file , so i want to use memcpy(fTo, p_buf, fMaxSize) to copy the PS tho fTo buffer,
but the   env->taskScheduler().doEventLoop(); to do the task for loop, but memcpy(fTo, p_buf, fMaxSize) is also in a while circular, it look like the 
this:
while(!signal)
{
    memcpy(fTo, p_buf, fMaxSize);
}

but i dont how to send the packet of fTo to client use RTP and RTCP, so i only to imitate testMPEG4VideoStream.cpp, but i dont know how to use while() instead of env->taskScheduler().doEventLoop()
